edit: Hmm... not really much out there. The Kei Office site is 'Under Construction', nothing there. I'm seeing that coilover kit for a few hundred less on a few sites, tho. I think I'll probably be sticking with the Tein kit... (my next big expenditure).
TEIN really arent that hot, from what ive seen (and ridden in) they are the least refined coilovers. All the parts are there if you get the right model (Tein RA has independant preload, height and dampening adjustment, upper pillowball monts etc) but in comparison to Kei Office (supragutz), Magic Garage (on onebad7m's car) and Zeal (My car), the TEIN's just have less then ideal results according to my butt dyno. Oh and im running 20k front and 14k rear as well, as long as you dial in the dampening those spring rates are superb. Whatever you get, if it doesnt have all independant adjustments, look for something else, youre wasting your money.
