Once you understand what ride heights are and what interactions ride heights have with suspension geometry, you need to spend a lot of time testing and experimenting with different settings in order to find out what works with each specific car. Finding the balance 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. Similarly, there is an ideal ride height range that minimizes aero drag. 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. Well get started with the basics that apply to any car and well progress to more advanced setup topics, which are only applicable to high-end cars. The differential (or diff, for short) allows the left and right wheels to rotate independently, which helps balance the car through corners. Get the Skip Barber out for a spin, and see if you can adjust the ARB to your liking! Limited slip differential 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. Nummer 6 - 2017; Nummer 5 - 2017; Nummer 4 - 2017; Nummer 3 - 2017; Nummer 2 - 2017 In general, aim to run the stiffest springs that still allow you to go over bumps (if a curb is giving problems, you may not want to counter it through setups, but just avoid hitting it). For example, softer springs will compress more on the straights, as higher speeds generate more downforce. How suspension geometry affects ride height Additional Terms of Use for Coaches. As we saw, both a spool and an open diff have their issues, especially in racing conditions. The coefficient on the left tyre decreases from 1.25 to 1.11, while on the right tyre it increases from 1.25 to 1.35. Open differential 20L. I was following the leader for about 15 laps within .5 seconds, and within .2 seconds for about 8 or 9 laps. Later on, well also focus on temperature and weather differences. Modify the suspension geometry so that you achieve the new desired camber (or toe) at that same ride height. And during cornering, lateral forces cause the body to roll which compresses the springs on the outside tires. You also have the option to opt-out of these cookies. Like discussed in the spring rates article, bottoming out can cause handling issues as one or multiple tires may become unloaded or lose contact with the track altogether, and it can also severely lower speed when the car is dragging onto the track. 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 went through a hole that looked clear, but I still got a 4x out of it, yet no damage or collision sounds/effects. 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. I would definitely suggest that you check out Setups4i.Racing over the iRacing forums if youre after a setup just to get you on the road as quickly as possible. Setups4i.Racing is run by Tanner McCullough youve probably seen him in Matt Malones YouTube videos or stream. If you find the car unwilling to turn, you can try stiffening the rear ARB.

You need to keep ride heights in mind each time you change any of the following: Its very easy to use whether youre accessing it from their web interface or their downloadable client. You are all, after all, just keeping the gas pedal on the floor the whole time. Stiffer rear springs give you a more consistent handling through the corners, while softer rear springs will give less drag on the straights. Excessive spin on the drive axle cause that axle to lose grip causing sudden oversteer (on RWD cars) or understeer (on FWD cars). For cars where aero is a defining factor in car setup, the ride height is the key to optimizing aero performance. 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). For example, here are the differential settings for the McLaren MP-30: You can achieve identical handling with completely different diff builds/configurations. Login Learn more Loading. Notable road car examples on iRacing are the V8 Supercars. Adjust these properties until your achieve the desired measurement for ride height. Well start with the Skip Barber RT2000, as it is the first open-setup car for most road racers, and also a car thats understandable and sensitive enough to observe setup differences with. Hem; Artiklar; Nummer. A higher tyre pressure alsochanges the curvature of the tyre, from a flat shape to like that of a bicycle. Sim Racing Setup. This guide defines each listing in the Garage section for each car available in the iRacing.com Motorsport Simulation. After the tyre pressures, which we handled in 5.2, another significant setting to tweak on the Skip Barber is the anti-roll bar (ARB) in the rear. Excessive front toe in will make a car turn into a corner quicker, & may create a loose condition. Spring rates and their effects Im a long time lurker on this sub, and i race oval exclusively. Run by Fans of the Worlds Leading Motorsport Simulation Game. I am pretty consistent. The Skip Barber, as a non-downforce car, can be driven with the same pressure at practically every track. This simplifies the front spring rates setup. So, running low pressures has its drawbacks, as does having too high a pressure. Super simple, nothing fancy about the layout of how its done. Quick View. iRacing Setup Download Terms, Reviewers who have tested the Thrustmaster T818 Direct Drive wheelbase are mostly unimpressed. Dirt StreetStock: 2/27/2023.

Travel to Japan, Australia, and the USA with Fuji International Speedway, Sandown International Motor Raceway, and Port Royal Speedway. The open diff presents challenges in low traction conditions. Less fuel equals faster speeds. Tire pressure: The tire is effectively a spring, and significant changes in tire pressure affect ride heights too. Using the ARB to balance the car First race ever, I was in 9th going into the last corner. Virtual Racing School. Second race, completely my fault. This is quite unfavorable when one tire is on a slippery surface like mud, grass, ice or wet track markings, as the tire on the slippery surface will end up spinning, consuming most of the available engine torque. It's better to learn collision avoidance in rookies, than jumping to higher level races without understanding proper racecraft. 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. Gaining proficiency in car setup is a process that requires you to experiment and analyze a lot. With this we mean the bumpiness of the surface, and the lengths of the straights, and whether there are many fast or slow corners. Dynamic ride height is the actual ground clearance at any moment in time as the car goes around the track. As a general rule of thumb, on tracks with lots of low speed corners such as Okayama, youll want to run relatively low pressures, because compared to high speed circuits like Spa, the downforce generated by the car is fairly low on Okayama, and therefore the loads on the tyres are lower. 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). Quick View. Welcome to the Unofficial iRacing Reddit Community. When playing with the pressures you should be able to notice differences in traction in slow corners between higher and lower pressures. 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. It set a minimum amount of locking force that is applied at all times. You can view and compare different packs here.
