Hi,
Over the week i swapped my suspension from stock "IS" to bilstein sports and M3 springs, what a difference, ride is a bit stiff but i like the way the tires are glued to the concrete now and a nice drop. so my question is to what bushings i can upgrade that will not require to get the car aligned afterwards, or is that inevitable.
i was reading that the suspension is the same for E30, E36 and E46's, which m3 spec bushings are better?
