Hi,
My car is currently dropped 2 1/4" with regular lowering springs. I tried to put camber kits on to correct my camber (tires wear out at 13,000 miles) but could not because my car is dropped to low--if I did the wheels would rub too much against my wheel wells. What I want to do is get the adjustable coilcovers/springs. Two questions:

1) how hard is it to do yourself?

2) how would i know that all 4 were adjusted to the same level
so that the car would be even? Are there measurement
notches on the springs to where I would know that each side
was lowered say 1 3/4 or 2"? Obviously, the car being
imbalanced is a concern.

Any input would be appreciated. Since everyone seems to include specs of the car, I guess I'll do the same
