Well I don't know about the whole wheel gap trend, I never swapped to new springs and Koni's for the look, I did it for the ride. I don't give a hoot about wheel gap, unless it's a clearance issue. But I can tell you I love my Prokits and Koni's for ride quality and adjustment.

If you drive your car in the winter, in an area with road salt, I highly recommend you pass on coil-overs. I don't care what they are made from you will get gauling on the threads and this will lead to threading issues of the spring perch.

Do what you want but road salt eats everything, yes even Stailess steel over time.
