Is body roll really the one that limits your speed in curves? Or it's just your confidence doesn't allow to push more due subjective feels from roll?
On what tires you are driving on track?

It's my understanding that too much body roll makes quicker transitions/weight transfer more difficult, but not enough body roll with cause you to have less grip because there is less weight transfer.

imho, tires play a bigger roll (if not the biggest) in determining how much grip your car has.


it's tough to determine what one element is the limiting factor in maximum cornering speed.

if you have two vehicles with the same suspension setups, but different tires, than sure you can say the tire's grip is the limiting factor.

once you start altering a cars suspension/alignment setup, there are too many variables to pinpoint what is holding you back from achieving your maximum corner speed.

ideally, if you're running time attack, and your car has the correct wheel/tire setup (slicks or competition slicks depending on class) the corner speed factor then shifts from your tire to whatever your suspension setup is.

this is why so many people try different setups, alignments, tires, ultimately trying to find what works best for them and the way they drive.

it's all very speculative and a lot of it is driver preference.


i hope this helps. I am by no means an expert so please correct anything I may have gotten wrong.

If you're trying to "keep the rear end more firm around tight curves", then it sounds like you're already unhappy with the car's tail-happy tendencies? If that's the case, then going to a bigger rear bar is just going to amplify that behavior, not reduce it.

So I'm using the Perrin rear endlinks on stock away bar. The diagrams that Perrin supply shows flexing/tension on the endlinks with the different spacer combinations.

On my setup, the natural position without flexing is end link towards the front, then 3 spacers to the rear. Correct me if I'm wrong, I wouldn't want flexing right unless I'm looking for a stiffer setup?
