The Eibach pro-kit drops less than the sportlines. The sportlines will drop to about 25" dead on from the ground to the fender through the center of the wheel. The ride is a bit less stiff than the pro-kit springs. Same goes for the H&R's supersports vs sports. Supersports drop more but are less stiff.
This is mine with Sportlines. Never rubbed with 18x8 - 45 offset wheels rolling 225/40 18 tires.
I just sold them a month ago for $80usd..I have had H&R supersports on for over a year now. I switched only because H&R's dropped the front a bit more where sportlines were an even drop. The ride is very similar with both.
