| Powertrix coil overs are way way better than the KYB / Eibach combo even on the street. I have been running the KYB setup on both cars. I just switched to the Powertrix setup as a result of the group buy (thanks Charles). I am still playing around with ride height, but even at the lowest settings the ride and handling of the convertible is dramatically bettter. It seems like the car settles much better and faster after you hit a bump. (Fewer oscillations before returning to steady state for you eng types). A side benefit is fewer rattles inside the vehicle. Car feels much more solid. I did four things this spring to the suspension that I am really happy about and would recommend to other convertible owners: coil overs, SZ subframe spacers, lightweight wheels (sorry Modas) and Hankook Ventus V012 evos. Ride and handling is way better. Going to run this setup on the track on Tuesday as my r888's are pretty much done. Obviously I am expecting big things - will report back.
