Coil-over kits designed for aggressive street applications and circuit use.  More adjustment capabilities for fine tuning the suspension system when trying to accomodate for different road conditions.  Especially useful for sensitive drivers that are looking for precise feedback and control.

The Street / Circuit level suspension coilovers are all full independent ride height adjustable meaning the spring preload & shock stroke is fully retained when changing the vehicle height. The shock absorbers all feature an adjustable dampening system.

Street Zero-A [Full Height Adjustable + 40 way Adjustable Damper]

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

An 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.

Sport Zero-3S [Full Height Adjustable + Inverted Shock+ 24 way Adjust]

Designed for sport competition driving.

This suspension coilover kit is designed with full adjustable ride height feature which retains full shock stroke length and spring preload.

The inverted shock is made from light weight aluminum and features a mono-tube 24-step shock absorber. The specific internal valving is designed both for those who mainly track their vehicles and at times, drive it on the street. The inverted damper prevents external elements from entering the shock casing and retains structural rigidity for added stress loads applied to the coilover.

Comes with camber adjustable pillow-ball upper mount and/or rubber upper seat depending on its vehicle application.

• High compression mono-tube shock absorber, valved primarily for circuit use
• Inverted shock design
• Full height adjustable structure
• Increased spring rates for sport performance
  
• Precision cut shock case thread with special coating
• Ribbed lower bracket made with di erent metal according to each vehicle.
• Each suspension exceeds over 500 hours of elemental testing standards
