Having been thru this before myself, I would discourage you from trying to nickle the coilover conversion to death. You really have to maintain suspension travel. Two ways to do this: sectioning the tube, or camber plates and elimination of the top strut insulator. If you do camber plates, the top spring perch is higher in the tower, effectively lowering the car without reducing travel. If you lower the car by lowering the bottom spring perch, or by shortening the spring, you have to re-gain that lost suspension travel by shortening he strut above the lower perch, ie "sectioning." I recommend that you wait until you can afford to do one or the other. I also want to say that I love my spring rates for both track and street: 225F/250R. Firm but not harsh.
