Product Details

The Ksport CLX050-RR is a purpose-built road racing coilover system engineered exclusively for competitive track use. Featuring aggressive spring rates and precision valving tuned for maximum handling response, this system delivers acute reaction and responsiveness demanded by serious road racers. For race use only — not intended for street or highway driving.

Damping & Adjustment:

  • 36 levels of damping adjustment for precise, fine-tuned handling control
  • Simultaneous compression and rebound adjustment via a single knob for quick, easy trackside tuning
  • Stiffer spring rates and valving matched specifically for road racing performance
  • 20–30mm shorter shock stroke compared to street-oriented coilover designs

Construction & Materials:

  • Lightweight 6061 billet aluminum mounts and hardware for reduced unsprung weight, superior durability, and rust resistance
  • Steel shock body with zinc electroplating for corrosion protection
  • Monotube design separates oil and gas within the cylinder for superior heat dissipation, finer damping adjustments, and reduced risk of aeration and cavitation compared to twin-tube designs
  • Each valving set is matched to the installed springs for consistent ride quality and long-term reliability

Upper Mounts & Geometry:

  • Pillow ball upper mounts (front and rear on select applications) preserve OEM suspension geometry while delivering a direct, communicative feel for improved driver response
  • Camber adjustment available through the pillow ball mount on certain applications — eliminating the need for a separate camber kit

Height Adjustment:

  • Adjustable lower mount design allows ride height changes without sacrificing suspension travel, a key advantage over conventional coilover designs

The Ksport CLX050-RR coilover kit is the ideal choice for track day competitors and road racing builds requiring uncompromising performance, precise damping control, and a lightweight, durable construction built to withstand the rigors of motorsport.

No problems ordering a leak down tester from Autoplicity which had the lowest price and reasonable shipping charges. The item was well packaged and I would buy from them again.
