Lower tyre pressures lower the vertical stiffness, which in turn causes a bigger contact patch (flatter tyre), and in theory sounds promising. Ride height (measured in mm or in) defines how far off the ground the chassis sits. The circuit has fast corners and fast straights, so a compromise is needed between the two baselines suggested above. I went through a hole that looked clear, but I still got a 4x out of it, yet no damage or collision sounds/effects. A spool gives you good traction accelerating on a straight line, but the handling of the car is compromised during turning. 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.

For example, softer springs will compress more on the straights, as higher speeds generate more downforce. A spool ensures both left and right tires rotate at exactly the same speed. Dynamic ride height is the actual ground clearance at any moment in time as the car goes around the track. 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. To give an example of an ARBs importance: When a car without an ARB installed goes through a fast right-hand corner, the inertia forces the car to lean to the left side, which is on the outside of the corner. If you want any other advice, or have any questions, PM me. Each time you make a change to ride heights you should remember to also take a look at camber and toe. In practice, you wouldnt make spring rate adjustments to affect roll-stiffness. Also, the trade-offs between different adjustments become quite interesting in the FR2.0.

All Rights Reserved. One of the super nice things about Craigs Setup Shop is the fact that you can also pay by subscribing to his Twitch account. In terms of handling, this causes understeer when decelerating, and oversteer when accelerating. Yet a bigger contact patch also increases the rolling resistance of the car. With this we mean the bumpiness of the surface, and the lengths of the straights, and whether there are many fast or slow corners. Its also one of the most important things to get right on every single car. 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. We suggest you select a track, default weather and start a test session. Once you get into a race, the same argument applies. I'm less worried about winning and more worried about not getting caught in wrecks, once you make it out of rookies its better. Finding the balance Sim Racing Setup.

Necessary cookies are absolutely essential for the website to function properly. So, running low pressures has its drawbacks, as does having too high a pressure. Lets say that number is 4 laps. Fuel load: Added fuel (per the example above, for full race distance as opposed to for qualifying) adds more weight to the car, which compresses the springs more, which reduces the ride heights. This helps us understand how effective our marketing campaigns are in leading to product purchases. 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. 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. A given tyre pressure is ideal for one specific amount of load on the tyres, yet this load varies greatly because of the different amount of downforce generated through high and low speed corners. iRacing Setup: A Beginner's Guide on How to Get Started Craigs Setup Shop costs $5 per month/$15 per quarter/$50 per year and this will give you access to all of the setups that are available.
