so im pretty sure (99%) that the fronts are usdm pinks because they're the only one with a white strip. my concern, now that i have the rear springs in front of me is a comparison to this link i found
http://www.iwsti.com/images/faq/pinkspring_note.jpg
the top most coil on my rear springs wrap up another 180 degrees, hence probably adding some overall height, and the paint marking on mine are much more towards being purple than those in the link
in terms of the gr-2s, i dont want to risk buying something that will fail, so what would you suggest, especially being that the top of the rear springs fit the 04/05 (i dont remember which) tophats that i have. ive heard some good things about the koni inserts, but my oem satruts have 135,000+ miles on them
