How does Sachs Sportin Kit compare with Bilstein/H&R?

[bahnstormer]

the reason the tires make a difference is the sidewall - depending on how much steel
they put in there....many companies now do that to keep the sidewall from flexing, esp
in a performance tire..

17's with kumho 712 with sachs kit - like love the look, raked front to back
the handling is crappy though...that could be amplified by my 235 front and 255 rears
but i think that the car needs to be corner weighted. if i were to buy suspension
today, i'd buy coilovers and corner weight the car, then i'd setup the car from there.

the suspension geometry is the same for the M5 and non M5.

Thanks for the info Brandon. Which suspension parts are you talking about swapping from the M5 to the 535? I've been told that the geometry is quite different on the two cars
