Hi, i have read your answers on M3 suspensions starting post 11 and 317 - but it would be really helpful for me to know is there any technical difference that will make it impossible to use m3 springs on a e46 coupe?
I'm asking because I need stiffer springs, because i have a TS setup + a cast iron block adding up to 50 kg to the front axle load. My current springs cannot cope under spirited driving and my choice is to go with 330diesel springs (front axle load 1030) or M3 springs if they can be used at all. I'm partial to Eibach and would buy their spring set for either 330d or m3.
Your help would be greatly appreciated, again :o)
