How are you guys tuning your chassis for road racing ? Every time I think Ive gotten my s4 tighter I continue to second guess any potential improvement to handling

 

well it helps to have some kind of data, so that you can actually look at some numbers and make tuning an objective thing, instead of just saying tighter.

the trick actually really is to figure out what you need to get the car to do,

the really basic thing, is just lap times. but there is a whole host of other things you can do, tire temps... measure peak G forces, yaw, cornering speed, steering wheel position, and speed, brake pressure....
