The main purpose of the ARB is to change the roll stiffness of the axle its installed on, which has two important implications: The ratio of roll stiffness between the front and rear axles affect the balance of the car, especially its tendency to under- or oversteer. A spool gives you good traction accelerating on a straight line, but the handling of the car is compromised during turning. If you want any other advice, or have any questions, PM me. Im a long time lurker on this sub, and i race oval exclusively. You have to use telemetry to find out after how many laps this takes. For now, start your setup crafting career by finding the right tyre pressure. For example, a bumpy slow track like Sebring could need softer springs. Blurring the line between real and virtual motorsports. The nature of the track would typically determine the baseline you start tuning from. This website uses cookies to improve your experience while you navigate through the website. This can improve the balance of the car, and increase overall grip on the axle as shown in the earlier example. 2: Balance between downforce and drag Also wasn't helped by the 20 laps I turned in testing where the car wouldn't break 120mph, so I say "wow, this is stupidly easy, you can't screw up" and join a practice session and all of a sudden I'm doing 140 running the same line You should be able to run the whole track without lifting off the gas. Tuesday at 18:58; 3; And during cornering, lateral forces cause the body to roll which compresses the springs on the outside tires. Setups4i.Racing I would slot into the best of the free options. This effect is most noticeable on the McLaren MP4-30 or Williams FW31, as theyre running on wheels with very tall sidewalls relative to their width. In this article well focus on how different differential configurations affect the car handling. 3: Ground clearance For cars where aero is a defining factor in car setup, the ride height is the key to optimizing aero performance. This helps us understand how effective our marketing campaigns are in leading to product purchases. There is a certain trust with the other drivers you build when you move up classes, and that trust is what makes for some really great side-by-side racing. You can also tweak other peoples settings to be more consistent with the way that you drive, and also to try and squeeze every last millisecond out of your lap times. If youre interested in the mechanical workings of a differential, we recommend you check out the following videos: How a Differential Works?, Understanding Limited Slip Differential, and Working of Limited Slip Differential. As with almost every setup option that will be covered later on, some compromise is needed. Iracing - Setup, Street Stock, Charlotte 5,269 views Jun 20, 2016 20 Dislike Share Save Murphy's Law NZ 2.26K subscribers Hi Guys, here is my setup for the Street Stock at Charlotte but. Example These cookies do not store any personal information. And obviously every single car is different, so the first thing you need to find out when you start setting up a new car is what bottoming out means in terms of ride height reading. splitter, tire, etc) and its vertical offset, the ride height as measured in the garage (and as reported in telemetry) does not necessarily equate the actual ground clearance. And so the front roll-stiffness is solely controlled by the front ARB, which is adjustable in the real car, but is fixed in iRacing. This track humbled me a little bit, and it really drills in the need to learn the proper lines. We recommend you take either of these for a spin on low tyre pressures, so you get familiar to the feeling of too-low tyre pressures. As always, its important to experiment with each setting to gain experience with the car and to develop an instinct for how to approach differential setup. I hate jumping into a practice session only to realize that I didnt put my setup in the setups folder. It is mandatory to procure user consent prior to running these cookies on your website. And weve discussed in 5.3, lateral weight transfer reduces the total available grip. Then increase the pressure a bit, and check behaviour and laptimes again. Virtual Racing School. Different simulators implement this differently, but in iRacing you cannot set the ride heights with one parameter. JavaScript is disabled. The setups that Setups4i.Racing offers are actually really good, especially for a free service, and if you can deal with the setups not being updated as fast as VRS or Craigs Setup Shop then this is the go-to service out of the free options. I've tried staying low the whole way round, middle all the way, starting middle and tightening to the line, starting high and tightening to the line, everything I can think of. do not, i repeat DO NOT try to race for position. To pass tech inspection, you need to raise the ride height. They also offer a free tier, however, it is pretty limited in what setups youll have access to. When playing with the pressures you should be able to notice differences in traction in slow corners between higher and lower pressures. Each VRS datapack consists of data from all relevant iRacing circuits with a setup, telemetry and a replay file from Pro drivers in the current season (Season 3, 2017). I didn't race any oval races until I was a B license in Road, and I was able to fast track out of rookie oval in a few days, while getting top 5's in every race. How suspension geometry affects ride height Splash = 2-3 gallons, 1/2 can = 5-6 gallons, 1 can = 11-12 gallons, 1 1/2 cans = 17-18 gallons, 2 cans = full tank. The long and short of it is this. From there stiffen the rear and see if it leads to laptime improvements. You can also use the anti-roll bar to help restore the balance of the car, just never change it together with the spring rates, because it makes it hard to tell which change is causing which effect. When changing spring rates you want to make sure that you maintain the ride height from before the spring rate adjustment (otherwise youll be applying two changes to the car). In this article well explain what ride height entails, how you can adjust it, and how it affects other setup adjustment. The spring rate is the measure of spring stiffness, and represents the amount of force required to compress the spring a certain distance. As a result, youll get a non-zero reading even if the splitter bottoms out. Towards the end I am usually down to 36.1 to 36.2s, maybe even 36.0s if I have a decent draft going, I am yet to break into the 35s however. Going with softer springs could solve the bounciness, but in return could hurt the pitch and roll attitude of the car, and may influence suspension geometry (such as camber), and consequently hurt aerodynamic effects and possibly cause aero-related handling issues. The final factor, relevant for both downforce and no-downforce cars, is clearance from the ground. best thing you can do for rookie class, is finish cleanly. If you ask too much of the car (overall Gs), the ARB wont help. Each car is different, but in general theres an ideal ride height range that produces maximum downforce. The process of finding a good tyre pressure, at least for short runs, is the same iterative process as with the lower end cars. And if you really dont care about anything i just said, and still want to jockey for position, then i would say the way to pass in the SS's is to go high on entry, coming down at exit (as long as its clear) and passing on the inside of the straight. Street Stock at Charlotte setup I know it's Week 13 and it's supposed to be just for fun, but I can't help being competitive I need a setup badly, the iRacing ones aren't great 5 0 iRacing Racing video game Sim game Gaming 0 comments Best Add a Comment [deleted] 2 yr. ago [removed] [deleted] 2 yr. ago [removed] More posts you may like Hugely helpful in becoming a faster driver!

You must log in or register to post here. Especially in road racing, driving style is typically a much more significant factor in lap times than car setup. The regulations allow the FR2.0s ride height to be very low, as a consequence you can run the stiffest front springs and still achieve your desired front ride height. Likewise, you should notice a difference in grip in higher speed corners, although this might be more difficult to notice. Explains how to select adjustments that may address the car's deficiencies in the beginning, middle and end of a corner. Stiffer springs will reduce body roll. Weight transfer causes the ride height to change. To find the ideal tyre pressure, its important to know what to look out for. YouTube, there is software to help you with that as well. For example, softer springs will compress more on the straights, as higher speeds generate more downforce. By multiplying the two numbers, you get the amount of friction force provided by the tyre: If we have a perfectly balanced axle where each wheel is loaded with 400 kg, the total available grip at that axle is: (400 x 1.25) + (400 x 1.25) = 1000 kg (axle). Depending on the location of the ride height sensor (e.g. Its configuration determines how much of the torque coming off the engine is transferred to each wheel. Unlike the front ARB, the bar in the rear is adjustable in stiffness. Lower dynamic ride heights are advantageous in reducing aero drag (unless the floor is scraping the track!). The iRacing , NASCAR hall of Fame driver Tony Stewart will make his first start since 2016 in the Xfinity race at Indianapolis Motor Speedway on July , Coming off of a very successful 2019 racing season, Billy Pauch Jr. only has one regret.

Yoeri Gijsen; Feb 22, 2012; Replies: 1; Views: 17k; Replies 1 Views 17k. So while the total load on the axle remains the same (800kg), the total available grip is now only 955 kg. Third race also my fault. Here's the list of the 7 Best iRacing setups shops: Craig's Setup Shop. Unless you are within 0.2-0.5s of your fastest teammate, or a VRS datapack, you are probably better off working on your driving style. A lower sitting car generally has better handling because a lower center of gravity means less lateral weight transfer. Lets dive in. First of all, you need to understand what an ARB is and what it does to the car. This category only includes cookies that ensures basic functionalities and security features of the website. Sim Racing Setup. So far I've had 1 incident in each race, one of which I don't see how I could have avoided. Coachdave academy.

The downloadable client that Craigs Setup Shop offers as well is really nice, mainly because Im lazy, but also because it keeps everything organized and is fast. Coming off the high side of the banking gives you a little run if you do it right, but its very easy to get loose doing this, so it comes with a risk. Finally, well look at a high-end, high-downforce car in the HPD ARX-01c. DIRT STREET STOCK SETUPS. Later on, well also focus on temperature and weather differences. If the car is nicer to drive and/or quicker, go into the same direction with the pressure another time. How to Open the Setups $4.99 per month for their Dedicated package, or $9.99(or $99.99 if you pay for a year in full) for the Competitive package. the BMW Z4 GT3 has its tank fairly far back in the car), setting the race fuel ride heights could be trickier. For instance, during braking a car with softer front springs compresses more on the front, which pitches the car forward (dynamic reduction of ride height at the front). BMW M Hybrid V8, Dallara P217, IMSA23: This helps with turning. Excessive spin on the drive axle cause that axle to lose grip causing sudden oversteer (on RWD cars) or understeer (on FWD cars). A spring rate adjustment affects the following: As we see, springs dont control a single variable in a straightforward way. The differential (or diff, for short) allows the left and right wheels to rotate independently, which helps balance the car through corners. Hem; Artiklar; Nummer. On tracks with fast straights and many flat, slow corners (such as Gilles Villeneuve, Montreal), youd like to start with stiff front springs and soft rear springs. In contrast, with the two springs at the rear of the car, roll stiffness is influenced by both the adjustable rear ARB and the rear springs. Spring rates and their effects Matching front and rear ride heights may be all you need to convert a qualifying setup to a race setup. Yes, you can just park your foot on the gas pedal -- but, no, that's not going to guarantee you consistent times. The closest I've come to actual racing was in the last race.

For example, the splitter ride height sensor (on cars that have one) may be positioned a few centimeters above the bottom of the splitter. This would allow you have a car with more consistent aero performance in all corners regardless of speed. Each time you add and remove fuel youd generally want to do so without actually modifying the static ride height (with some exceptions, depending on car or track). The only difference between you and the people qualifying way ahead of you is the path you take on the track. The red component in the illustration below is an anti-roll bar, which nearly every racing car has on its rear and/or front axles. Camber & toe: As already discussed, camber and toe adjustments may affect the ride height. One of the few setup options available to the Skip Barber car is the pressure in the tyres. Some are far more secretive. We use analytics to determine how users use our website and look for opportunities within these datasets to improve our site design. The circuit has fast corners and fast straights, so a compromise is needed between the two baselines suggested above. The only way to pass I've found is to wait for the guy ahead to make a mistake, but being close enough to capitalize on that mistake seems to be rather dangerous from watching the guys ahead of be get punted into the wall. I'm really hoping the next class is way cleaner. The dynamic ride heights also changes throughout a stint, for as the fuel burns off and the tank empties, the car becomes lighter and therefore rises. To understand how balance is affected, we need to understand that as vertical load on a tyre is increased, the coefficient of friction of that tyre decreases. Quick View. Excessive front toe in will make a car turn into a corner quicker, & may create a loose condition. The same applies to each wheels toe-in. Bristol Motor Speedway Asphalt Street Stock Setups; Charlotte Motor Speedway Asphalt Street Stock Setups; Concord Speedway Asphalt Street Stock Setups; Five Flags Speedway Asphalt Street Stock Setups In order to increase ground clearance, youll need to decrease the perch offset on each wheel, or increase the pushrod length (when available). For further explanations on the matter of ARBs, please see the more advanced chapters of this guide, which well publish soon. I dont create my own setups for the reasons just mentioned. Featured. Dynamic ride height is the actual ground clearance at any moment in time as the car goes around the track. One of these tools is car setup.

The setups come from a wide range of sources across the iRacing community, meaning the quality of setup isn't always guaranteed like it is with professional paid setups. Modify the suspension geometry so that you achieve the new desired camber (or toe) at that same ride height. It is there to improve your site experience by saving your preferences. I encourage rookies to race to win, while learning to race clean. And if you want to record your races and/or stream them on e.g. . The spring rates hugely affect mechanical grip, but also aerodynamics, which may surprise you. As you can already see in the setup-screen, there is only one center mounted spring and damper in the front, with non adjustable ARB. It's just me or is this track not good for the car? This essentially causes spring stiffness to have no significant effect on the mechanical balance (lateral load transfer distribution and roll) of the car. si far I've done 3 races on rookie Street stock, coming in 6th 11th and 2nd. You can do your setups yourself if youd like, and this is a really good idea to at least have a go at some stage in your sim racing life. The FR 2.0 has more setup options available, including an important one, which will vary greatly between circuits: the selection of front and rear springs. Its measured in Newtons per millimeter (N/mm) or pounds per inch (lbf/in). This may change your ride height again, so you may have to do a few iterations of ride height adjustment, camber adjustment, until you achieve the desired result. Setting up a car is about trade-offs within the limits of physics. A locking differential can behave both as an open differential and as a spool. In the rear are two separate spring and damper units. Additional Terms of Use for Coaches. CONTACT. You may consider the preload as a form of general trigger for sensitivity. Similarly, there is an ideal ride height range that minimizes aero drag. For cars where the gas tank is located far from the center of gravity of the car (e.g. A spool ensures both left and right tires rotate at exactly the same speed. As you progress through your iRacing career, competition is fiercer and youll need to use all the tools in the box to find the edge over your rivals. The spool is essentially a solid axle connection between the left and right wheels, or a fixed differential. Typically, its best to keep a note of the target ride heights as they are in the qualifying setup and try to resemble those as close as possible on the race setup.

Limited slip differential Get complacent/tired/something in the final laps and get an off track on the dog leg. As fuel is burnt throughout a stint the front or back of the car will get lighter, increasing the ride height. This guide defines each listing in the Garage section for each car available in the iRacing.com Motorsport Simulation. A limited slip differential might have any (or none) of the following adjustments available, but heres what they do: Each car in iRacing has a different differential settings available, under different names and configuration values. 2018. Controlling how much lateral load is transferred on the front versus rear axle is a balancing act, to optimise how much grip is available at each axle. See if you feel the effect of it, and try to visualise the forces working on the car as you go through the corners. Internet racing is a fun, easy, and inexpensive way for race fan and gamers alike to enjoy the thrill of the racetrack from the comfort of their home. When the pressures stabilize, you have reached the stable operating temperature of the tyres. Moreover, lower tyre pressures also affect the lateral stiffness, and when running very low pressures, its possible that the middle of the tyre is no longer at the centre of the rim while cornering. However, heres a starting point when you think about each diff setting: Static ride height is one of the key setup adjustments, and also one of the easiest to get right. Side-by-side racing is just something you cant do in rookies.

I went through a hole that looked clear, but I still got a 4x out of it, yet no damage or collision sounds/effects. Yet a bigger contact patch also increases the rolling resistance of the car. An ARB can balance this out. Tuning the rear ARB on the Skip Barber car is mostly a question of driver preference: If you find the car too unstable for your liking, you can try reducing rear ARB stiffness. You are all, after all, just keeping the gas pedal on the floor the whole time. As I said, they can be a good resource but they can also be very hit and miss and, personally, I would rather just go directly to a resource that I know Im going to get a quality setup each and every time. You should be able to distinguish driver errors causing understeer, from a car setup change causing understeer. The Charlotte Motor Speedway built a new infield road course, designed specifically for NASCAR competition, in 2018. Welcome to the Unofficial iRacing Reddit Community. Youd consider changing the ramp when you want to modify handling under braking (entry) without impacting the handling under acceleration (exit). The $9.99 tier gives you access to setups for every car in the service. The iRacing Forums come in at last for me as theyre just inconvenient and unpredictable. A completely open differential allows the left and right tires to rotate entirely independently. If a spring rate adjustment (for a different reason) results in undesired impact on roll-stiffness, youd counter that effect with an ARB adjustment. New members only. Static versus dynamic ride heights eNASCAR Class A, B, and Class C Truck Setup Guides, 30 iRacing datapacks (setups, replays, telemetry) now on VRS, 5.4: Spring rates basics (Formula Renault 2.0), 5.3: Anti-roll bar basics (Skip Barber F2000), 5.2: Tyre pressures basics (Skip Barber F2000), 1.4.2: Hardware, steering wheel, pedals & rig, Additional Terms of Use for Coaching Platform. Charlotte Dirt Track -- Dirt Street Stock Setup Package . You want to start with changing the number of plates to control how quickly the differential builds up locking force. In oval racing, its much easier to learn the tracks, so car setup is a quite significant factor in open setup series. The ARB stiffness can also determine the lateral load transfer between the front and rear axles, even if a car only has one ARB, like the Skippy, which only has one on the rear. A stiffer rear ARB causes more of the lateral load transfer to be distributed to the rear axle. Some people weld their differential fixed, for instance to allow easier drifting.
