¶ Anti Roll bars
Anti roll bars are used to limit the roll during cornering and hence affects load transfer.
Small changes in anti roll bar thickness has a large affect on the handling balance of the car.
A safe starting setup on the MX8 for most tracks is 2.3mm front, 2.5mm rear. If the traction is higher, or there are high speed sections, 2.6mm rear may help with rear end support.
As traction increases (within "normal" boundaries) it is expected to increase the thickness of the anti roll bars to control the roll.
Once the traction goes above a limit (to "Very high traction", the car will become more difficult to drive as the stiffness is too much, with the car becoming twitchy. This can be seen when the inside rear tyre lifts off the ground when entering a corner. Whenever there are not 4 tyres in contact with the ground, this can be addressed. If this is seen, the anti roll bars thickness should be reduced, with the shock package adjusted to control the roll. The car will roll more with the lower anti roll bars, but the rate at which it rolls will be reduced with thicker shock oils to make the car easier to drive.
