My car is an M20 swapped street car, and I have front coilovers that need springs. It is a koni race strut,, IE spring perches, e21 hub, IE camber plates. Anyone have any input on what front spring/rate/height to get? My only find so far:
For the rear, I have Bilstein Sport struts and just want to add height adjust ability and a OEM style rear spring to closely match the front. Don't want to go coilover because of the fab work involved with reinforcing the strut towers.
Maybe IE perches? But what rear spring?
Ground control makes these, and can possibly provide different spring rates, but I'm a little lost on what spring rate I would need..
