i have neuspeed race springs and neuspeed koni sp3's yellows on my 00 4 door gsr.It rides great,no rubbing whatsoever, and i would highly recommend this setup.

 

I run Omni Power full coil setup myself, they're good for the price and they have a large piston so you can run higher spring rates and it'll still be decently smooth.

Another thing hat omni has over coils + sleeves, is the advantage of adjusting the hieght of the car with out messing up the spring preload. :thumbup::thumbup:

Contact me if you want a set.
