best street coil overs?

EGAR

I'm running the Powertrix (SS) Sport Street Coilovers. They are the most streetable coilover set up I've ever been on. Ive rode in cars with Tien and KWs and definitely like the Powertrix set up the most. Powertrix specificly valves the shock for the Z34 and has uniquely tuned their high speed valving for the street on the softer settings with just enough performance to do canyon carving and some light autocrossing. Also what is unique is their upper mounts that are a synthetic rubber surround instead of the common pillow ball mount to help with a lot of the jarring and vibration inherent with the most coilovers.

The Powertrix SS also offers separate ride height adjustment from spring preload which is very important to ride quality. A feature which is absent on both KW V3, Tien SS and most other "street coilovers"
