Let me guess, you're thinking off powertrix coil overs? I don't much about them, if you do let me know how they perform.

Actually yes. I had KW's in mind at first because of how well they perform and it's fearures that's built and proven for track. Then I thought about what do I need that for anyway? I don't track. The lowest quote I got for KW was $1850 cash plus $250 install. For that price I can get powerfrix c/o with swift spring option, a set of hotchkis sways installed, SS brake lines and pads. Powertrix will also set me up with a calibration and check up after 90 days. They're proven in the Z32 community and the c/o they built was designed and spec'd for the z. Built by the same facility that makes Stance, KTS, Buddy Club, etc.

You gotta let me know where to find more info on those, I'd like the option of upgrading to the swift spring. Stance offer swift upgrade but only for z33, I'm not sure but they ay make it available for z34 too, Im in the process of finding out. Pm me about the power trix
