what's up? i am going to lower my car(87 325) and do some suspension work. i have a few questions. 1. how low do the bav autosport springs lower the car? i don't know how low 30mm is. 2. do they go with bilstein sports or streets(cause there's a really good sale on BAV AUTO) 3. what else do i need to completely lower my car besides camber plates? BTW i also plan on getting sway/stress bars after i go autocrossing to experiment. thanks. also, i am not lowering my car specifically for the look, even though i would like it,but more for handling.
