hey i can also get kyb stuts with GR-2 springs they are slightly used though do you guys think that this would be a better setup then the koni reds with the tom motosport coil overs? i can get them for about the same price, also when i replace them how do i know if the top mount are good or should i just replace them ?

GR-2's are a stock replacement... waste of money if your lowering the car.

Koni reds kinda suck, they area good struts and FAR better then GR-2's but they are a discontinued design and a paid in the ass to adjust. To adjust the struts you have to remove them form the car, take spring off, compress the strut all the way and twist then put it all back together and get an alignment again.

define slighlty used......

dont buy used. they could be shot ,but just not leaking. you never know.
