The nature of the track would typically determine the baseline you start tuning from. 0 . The same applies to each wheels toe-in. 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. However, with higher end cars, especially those with high amounts of downforce, finding the right tyre pressure becomes a little more complex. D. R 4.00. . 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. after you downloaded the setup, how do you use it?

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. 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). Tuesday at 18:58; 3; A locking differential can behave both as an open differential and as a spool. Weight transfer causes the ride height to change. The iRacing Forums come in at last for me as theyre just inconvenient and unpredictable. 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. si far I've done 3 races on rookie Street stock, coming in 6th 11th and 2nd. 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. iRacing Setup Sync is the one and only setup sharing application for iRacing.com. With the turns so gentle and banked, you can almost lay a brick on the gas and take a nap. Matching front and rear ride heights may be all you need to convert a qualifying setup to a race setup.

For cars that are not very aero dependant the ride heights are primarily used to affect the center of gravity. iRacing Late Model Stock Car gets much-needed Update. Aside from mechanical grip, an increased pitch (also known as rake) may also have aerodynamic effects, because the angle of the car changes. I'm really hoping the next class is way cleaner. Try fiddling with the spring rates, and see if you can improve your laptime with it. Excessive spin on the drive axle cause that axle to lose grip causing sudden oversteer (on RWD cars) or understeer (on FWD cars). The more locking force, the more it behaves like a locked diff and vice versa, the less locking force, the more it behaves like an open diff. Notable road car examples on iRacing are the V8 Supercars. 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). Some people weld their differential fixed, for instance to allow easier drifting. You also have the option to opt-out of these cookies. Finally, well look at a high-end, high-downforce car in the HPD ARX-01c. 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. In order to increase ground clearance, youll need to decrease the perch offset on each wheel, or increase the pushrod length (when available). the BMW Z4 GT3 has its tank fairly far back in the car), setting the race fuel ride heights could be trickier.

Ive only been using Craigs Setup Shop for a few months now but so far I really like it! Use the baseline setup, and drive a few laps to get the heat into the tyres. For example, softer springs will compress more on the straights, as higher speeds generate more downforce. As with almost every setup option that will be covered later on, some compromise is needed. 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. Finding the balance 550 kg + 405 kg = 955 kg (axle). If a spring rate adjustment (for a different reason) results in undesired impact on roll-stiffness, youd counter that effect with an ARB adjustment. The spool is essentially a solid axle connection between the left and right wheels, or a fixed differential. Try to visualise this in your mind.
