Okay, so I'm about to order a new set of performance brakes as I have killed my stock ones (hard braking from well over 100mph does a job on your brakes quick). I really wanted to get the Eibach pro kit, but lowering my car over an inch will probably not be a very good idea if I ever want to trade it, etc. I noticed that H&R makes a sport spring that lowers the frond by 0.75 inch and the rear by 0.50 inch.

Will I notice any difference in the cars handling, braking, and accel with these kit, or would I be better off leaving it stock? Does anyone here have this kit?

 

Not much of an improvement... they're called "Original Equipment Sport" because that's what they are, replacement springs with a tad bit of improvement. No serious gains.

 

Thanks for the heads up...I maybe just have to go to the Eibach Pro Kit...

 

Why not get H&R Sport or Race? What are your goals?

BUT, you said you want performance brakes... what does that have to do with suspension?
