okay, I didnt mean low as slammed, as my ex E46 in the sig

but lower than stock, 2-3cm will be optimal. and also, do you drive your car on track? if not, there is no point going to these depths on suspension.. unfortunately I dont have the time to study it, and I dont need it anyway

but from my experience with driving low cars for quite some time I can tell you, that lower car is faster in corners, and its not only because of lower center of gravity, but also because of the elimination of car roll in corners..
btw the example is really not saying anything, because I can also bring up examples of cars which are lower

and I dont have to go far, from the website you posted, take a look

you dont have a dtm car, so you cant look and compare to them, mainly because of the things you said, the suspension is re-done.. track day car is very different from dtm racecar which is built for one purpose from scratch..
anyway, so these guys are doing it wrong?



even the out of the factory bmw M235i race

just sayin

you have good suspension, you should try it.. reading online doesnt help at all

try to put it down 3-4cm allround, and you will see which setup you like better. thats why are the coilovers great
