Hey i'm currently running prokit with koni's and i think the ride and handling are pretty good. The pic in my signature shows my car when i had Neuspeed sport springs. They lower 1.75" front and 1.5" rear. I always thought the Neuspeed Sports and H&R Sports were manufactured by the same people. Both progressive rate and exact same lowering. One thing im not sure if I like is the fact that the Neuspeeds i had were set up to where the car actually rode on the bumpstops.
The pro kit instructions had me trim the front bumpstops so that the car wouldnt hit them during suspension bound. But for the Neuspeed Sports, the instructions said do NOT trim the bumpstops, and the springs sat lower than the 1.3" all around for the pro kit. I know that the Neuspeed springs were designed to RIDE on the bumpstops for a fact because: I originally had the pro kit installed on my car, trimmed the bumpstops like it said, and the car sat at about 1.3" lower like it was supposed to. I later decide that I wanted it lower, and the Neuspeed Sports seemed to be choice. So, I installed the Neuspeeds and FORGOT that i had trimmed the bumpstop from before, and the car sat OVER 2" lower in the front than stock. I was upset by this, so decided to read the instructions after the fact..

. In Neuspeed's instructions it said DO NOT trim the bumpstops. Sooo I went to the dealer and bought another set of bumpstops and installed them in the front. TA DA!! The car then sat perfect, closer to the 1.75" that it claimed and looked very nice (as you can see in my sig).
So that being said, did you guys have the same experience with the H&R Sports? Did you guys trim your bumpstops or no? I talked to a tech over the phone from Neuspeed and he said "yes the springs were designed to ride on the bumpstops, as they were taken into consideration for the overall spring rate." I personally think this is rediculous for a company to design a spring so that it doesnt even hold up the entire weight of the car, and instead leaving it up to the BUMP STOP to hold the car up!
So yes i like the pro kit overall for ride and handling, but 1.3" drop just isnt enough if you ask me, especially if you have plus sized wheels and tires. The Neuspeed sports are the perfect drop to me, but its just a little unsettling to think that the car is held in place by bumpstops. Im not saying the bumpstops are holding 100% of the weight, but just enough to keep the car at a certain height. I'm sure the springs hold a fair amount of the weight.
What do you guys think about it? Do H&R's behave the same way?
