I am on the verge of purchasing a set of 18X8.5 Hyperblack CSL's on 225/40s, along with some springs to compensate for the extra height. After doing the calculations I have discovered that the Pro-Kit will in fact only lower my car about a 1/4 of an inch lower than stock ride height, which doesnt seem that much at all. The sportline's however, should lower it almost 1 inch. Which ones should I go with? Does anybody have a similer setup? I'm not looking to slam the car, I just want it to ride a bit lower and still look great. Any advice at all would be much appreciated.
