Cornering causes lateral (left/right) load transfer at each axle. 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. This simplifies the front spring rates setup.

Lets work through an example, using the chart above. Such a setup would produce more rake (and downforce) in the slow corners and less drag on straights. JavaScript is disabled. 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. Im a long time lurker on this sub, and i race oval exclusively. Recent Reviews: Very Positive (26) All Reviews: Consequently, there may not be enough torque going to the tire on the grippy surface, so acceleration would suffer. This is a topic for another article, but it is a very nice software that you can use to see exactly where youre losing time and compare your laps to the pros, down to the millisecond. And during cornering, lateral forces cause the body to roll which compresses the springs on the outside tires. You are using an out of date browser. It means that you develop a deeper understanding of what the car is doing and how to drive it. A completely open differential allows the left and right tires to rotate entirely independently. Some series are very generous with people posting up their setups each week. The closest I've come to actual racing was in the last race. To pass tech inspection, you need to raise the ride height. 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. Welcome to the Unofficial iRacing Reddit Community. The ARB connects the suspension elements of two wheels on the same axle. 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. As a result, as soon as one wheel moves up or down, the other wheel is forced to follow that motion. Youd need to drive 4 + 5 laps (4 laps to get the tires warmed up, then 5 clean laps within a few tenths of each other). Pick up a decent setup (from the forums or a VRS datapack) first and focus on driving style until you are able to turn competitive lap times in the chosen setup. For example, a bumpy slow track like Sebring could need softer springs. You may have to take this into consideration when determining the static ride heights with a full tank. Gaining proficiency in car setup is a process that requires you to experiment and analyze a lot. Ride height (measured in mm or in) defines how far off the ground the chassis sits. Camber & toe: As already discussed, camber and toe adjustments may affect the ride height. Rookie DIRTcar Street Stock Extreme Simracing Series - Fixed: Limaland Motorsports Park.

For example, here are the differential settings for the McLaren MP-30: You can achieve identical handling with completely different diff builds/configurations. New members only. A tyre is a spring and damper unit after all, and becomes stiffer with higher tyre pressures. It works pretty consistently with the rookies. These cookies are used to provide a customized experience and can be used to provide targeted ads through advertising networks. Currently, I am using Craigs Setup Shop as it was pretty much free with my Twitch Prime subscription and the setups are on-par, if not better for my driving style than VRS. By statically and/or dynamically adjusting the ride heights, you can optimize the aero performance of the car. 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. It utilizes nearly all of the 1.5 mile oval as well as newly built infield portion - thus the name Roval (Road/Oval). To find the ideal tyre pressure, its important to know what to look out for. If you find the car unwilling to turn, you can try stiffening the rear ARB. It can cause the sidewalls of the tyres to nearly fold. Bring a 3.42 rookie it sucked soo bad getting here. The next track in the series is all about braking points and slip angle. I'm really hoping the next class is way cleaner. Virtual Racing School. This can improve the balance of the car, and increase overall grip on the axle as shown in the earlier example. Each car is different, but in general theres an ideal ride height range that produces maximum downforce. 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. The Dirt Track at Charlotte. Each time you make a change to ride heights you should remember to also take a look at camber and toe. Lower dynamic ride heights are advantageous in reducing aero drag (unless the floor is scraping the track!). The circuit has fast corners and fast straights, so a compromise is needed between the two baselines suggested above. Keep in mind that many suspension elements are connected. iRacing Asphalt Street Stock Setups for Southern National Speedway iRacing setups for the Asphalt Street Stock Car at Southern National Speedway are available on these pages. With the turns so gentle and banked, you can almost lay a brick on the gas and take a nap. A popular locking differential is the Detroit Locker, used in NASCAR. Necessary cookies are absolutely essential for the website to function properly. Its measured in Newtons per millimeter (N/mm) or pounds per inch (lbf/in). This series is Fixed Setup. 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. 1: Lower center of gravity means less lateral weight transfer, which means more grip Lets get to know the suspension layout for the FR2.0. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. In practice, when setting up the car, adjusting spring rates comes in handy when optimising aero effects, and the tradeoff is typically between aero related time gains (lower drag on the straights) and car handling (more downforce in the corners). si far I've done 3 races on rookie Street stock, coming in 6th 11th and 2nd. Softer rear ARB means more of the lateral load transfer is distributed to the front axle. iRacing's in-game options control panel - Click "Strength" and it will change to "Max force" If you are using Load Cell pedals, set the Brake "Force factor" to 0. Here's the list of the 7 Best iRacing setups shops: Craig's Setup Shop. Quick View. For cars where aero is a defining factor in car setup, the ride height is the key to optimizing aero performance. Fortunately, for the Skip Barber car and its tyres, finding the ideal pressure is fairly easy and does not depend on the track or weather conditions too much. See also thePC & screens, and the summary. And in a later article well look more closely how to approach dynamic ride heights. I agree on not trying to race for position. When going around a corner, the outside tire has to travel a longer distance. When playing with the pressures you should be able to notice differences in traction in slow corners between higher and lower pressures. Youll find that there are often a lot of setups posted when a new car has just been released. This single spring design at the front is called a monoshock. Dynamic ride height is the actual ground clearance at any moment in time as the car goes around the track. The only difference between you and the people qualifying way ahead of you is the path you take on the track. For now, start your setup crafting career by finding the right tyre pressure. Couldn't preach this more. A locking differential can behave both as an open differential and as a spool. Tire pressure: The tire is effectively a spring, and significant changes in tire pressure affect ride heights too. The $9.99 tier gives you access to setups for every car in the service. Alright, this is the first of the free ones, and honestly, its kind of a pain in the ass. Copyright 2023 iRacing.com Motorsport Simulations, LLC. Once you get into a race, the same argument applies.

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. Blurring the line between real and virtual motorsports. A higher tyre pressure alsochanges the curvature of the tyre, from a flat shape to like that of a bicycle. A very nice added bonus with VRS is that youll have access to all their telemetry software and logging data. Observe the car and check your laptimes. So while the total load on the axle remains the same (800kg), the total available grip is now only 955 kg. Its configuration determines how much of the torque coming off the engine is transferred to each wheel. When the available grip of the rear tyres is exceeded first, the car goes into oversteer; when the grip of the front tyres is exceeded first, the car goes into understeer. Likewise, you should notice a difference in grip in higher speed corners, although this might be more difficult to notice. Tyre pressures influence a number of factors in the performance of the car, and both high and low tyre pressures have their drawbacks. You cant really ask for much more. Try fiddling with the spring rates, and see if you can improve your laptime with it. Setting up a car is about trade-offs within the limits of physics. I like to juke like I'm going to pass right on the back straight, then pull down low when the person in front tries to block. I have played around with them before and I have an okay idea on what tweaking certain things do, but I do not have the time or want to create my own. 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. In the following series of blog posts were trying to shed some light on the various hardware parts you need to have or for some parts should have. It is characteristic of a monoshock that the front spring has no effect on roll-stiffness. Side-by-side racing is just something you cant do in rookies.
