I have a pair of front M5 shocks and a pair of boge sport/mtech shocks, which would be the best with a set og H&R springs??
The pisten of the M5 shocks is twice the lenght og the sports shocks. I have been told that is because the m5 shocks only work one way and the sports shocks works 2 way.
But with the m5 shocks, the spring is loose until the the weight of the car sits down on it. With the sports shocks the spring is tight even before the weight of the car.
Are the m5 springs that much longer than normal lowering springs??
I am using M5 top mounts and the 3mm rubber "things"

Sorry about my english, hope you understand what I mean
