Hi folks. I have been offered some springs from a Bilstein B12 kit, and as I need a new rear spring on my sport, am tempted by them. But I have heard people mention Eibach Pro Kit springs.
I would like to know if anyone knows what the Bilstein springs would be like compared to the stuff you get as standard on the Spart's Avus pack suspension?
And also, if I go Eibach Pro Kit, do i buy the springs for the regular 328, as these appear to be the same for all the 6 cyl models, or should I go for the M3 3.0 set?
