The KYB's and Tokico Illumina's are both good, but the KYB's have been known to sag earlier than the Tokico's. Both are good, but you get what you pay for.

IMO, Skunk2 coilovers are better than GC because of the locking perch design and the springs are better.

I can get all of these items cheaper than SpeedAssholes and faster, too. I deal with WestCoastStyle, so check his ratings out.
