Tokicos. I have them and absolutely love them. However, you may have a tough time finding the complete kit. Everywhere I tried (this was back in June 07) couldn't get the Tokico springs, even though they advertised the complete kit. I ended up w/ Tokico struts under Tein S Tech springs. I added white line sway bars and Bridgestone
Potenza RE960AS Pole Position tires (don't forget the tires - best suspension set up in the world won't help on shitty tires). This combo is fantastic. I have a 50 mile winding commute to work that I take mostly at 80-100 mph. I've never felt anything even consider letting go. Tokicos all the way. GR2 is basically your stock OEM setup.
