The Street ZERO-A features a full height adjustable system enables the perfect ride height adjustment without sacrificing damper stroke or spring preload. The newly developed 40 way adjustable twin-tube shock absorber system enables a wide range of suspension setting suitable for virtually any given road condition.
Factory upper mounts are re- used for those who prefer comfort, or Cusco pillowball upper mounts (sold separately) can be incorporated into the kit for more adjustment capabilities and direct road feedback.

Each coilover suspension is specially valved and dimensionally designed per vehicle application. The new CPRV valve is a pressure dependent system where it prevents the piston speed from falling below a sufficient "comfort" level. This suspension coilover unit does it all, from street to circuit, and its 40 way needle valve dampening characteristics can be changed with a single push of a button. (via Econ2).

CPRV Internal Pressure Valve Technology
A pressure dependant bypass is designed at the base of the damper rod where the amount of hydraulic fluid passes through is automatically compensated for the perfect dampening rate. This feature serves vital when the dampening approaches a dangerously low level typically experienced at the low and mid shock dampening rate.
