OP, you should have local Koni and Bilstein options. Hell, if you have standard springs, throw some KYB dampers in and enjoy.
If you're after adjustability, spend the money on KW (unless you just want height adjustment, then you can get TEIN street, they're relatively comfortable and cheaper).
Nismo S-Tune is a good bolt in upgrade, KYB dampers and uprated springs. Dunno if it's worth the money though.
