shock specifically valved for the springs. Very nice setup IMO, and very cost effective. Stiffer than H&R Sport not as stiff as race. I say definatly go for it.
You have a full M3 suspension? What is "MTECH" suspension? What all parts does that include.
Also, if you or anyone elce wants to buy my H&R Sport and Koni Adjustable shock/strut suspension combo. PM me
