Got an 02z with bolt ons(pacesetter Lts, TSP ORY, ported tb,vig2800,shift kit, tranny cooler, SLP lid and CAI, tune, 160 stat, granatelli fuel pump, magnaflow cat back, 3.73s) The rest is stock. Anybody have advice or a site for suspension mods. I plan to do heads and cam later, but don't have specifics on them yet. Will probably get 17" or 18" rims and some 275 or wider ET street or drag radial tires, at least in the rear. I have 16" rims with 245/50r16s all around now. My ultimate goal is to beat stock z06 vets and remain as streetable as possible. Keep around 12 mpg or so. I drive the car probably around 35 miles a day. When should I start to mod the suspension and where to start? ps I have an a4. Thanks
