Is it bad to cut aftermarket springs? If so why? A friend of mine is telling me that it is alright to cut them since they are aftermarket, and that it wont mess up my ride. But i highly doubt this for some reason.

 

Its almost always bad to cut springs. If you need them lower, buy different springs or GC coil-over kit with 2.5" ID Eibach springs.

Race series that use spec springs often allow the racers to cut them for corner weighting.

 

Yes and No.

The car will likely be low and not quite stiff enough to stay off the bump-stops.

If you want to go lower for some reason (which begs the question.. why do you want to go lower?), get a decent set of adjustable coilovers.

My 82 and 83 RX-7s have cut aftermarket springs. I do it because I race them and the spring selection is restricted. The fact that the 83 is a street car is irrelevant - I wanted it setup like the racecar.
