Hi guys im wanting to get some coilovers on my car as it looks like a Q7 at present, was thinking ebay jobs as ive had good results with these on my B5.5 passat, do i need to get particular ones for the quattro? also will they affect the 4x4 system? Finally with regard to rims do i need to get special fitment rims or will any audi wheels do? Reason i ask is that a mate has a set of 18" rs4 reps but they dont fit his b5.5 passat 4motion.. Thanks.
