Couple of things, ...
1) Spoolinmp3 (owner of spool-turbo) is a regular here. Surprised he hasn't said hi yet.
2) Springs are supposed to be good. I haven't had any direct interaction with Spoolin, but if he's selling them I wouldn't hesitate to buy them. I have the Racing Beat springs myself, but I didn't want to go too low, I wanted handling over aesthetics (and I got them for my B-day)
3) If it's more aesthetics that you're looking for, what about the ground control coil overs? Only 400, and I believe it goes from stock to a 3 in drop (?)
4) Did your friend get an alignment after he installed his springs? Are you planning to?
