Product Details

The Ksport Version RR (CBM031-RR) is a purpose-built road race coilover system engineered exclusively for competitive track use. Featuring stiffer spring rates and aggressive shock valving, this kit delivers maximum handling precision, acute cornering response, and uncompromising on-track performance. The shock stroke is 20–30mm shorter than street-oriented systems, optimizing geometry for road racing applications. For race use only — not intended for street driving.

Damping & Valving

  • 36-way damping adjustment allows precise fine-tuning of suspension behavior for varying track conditions
  • Simultaneous compression and rebound adjustment simplifies setup changes at the track
  • Damping is adjusted from the top of the shock on non-inverted applications
  • Spring valving is matched to installed spring rates for consistent, reliable performance

Construction & Materials

  • Mounts, spring perches, and locking collars machined from 6061-T6 billet aluminum for a lightweight, durable, and corrosion-resistant build
  • Steel shock bodies are zinc electroplated to resist rust and environmental exposure
  • Kit includes an anti-rust paste packet for application to critical coilover areas

Monotube High-Pressure Design

  • Oil and gas are fully separated within the cylinder for superior heat dissipation compared to twin-tube designs
  • Reduced aeration and cavitation result in more consistent damping force and ride quality
  • Enables finer damping adjustments than twin-tube construction allows

Height & Geometry Adjustment

  • Adjustable lower mount on most applications allows ride height changes without sacrificing suspension travel
  • Ride height can be lowered 2" to 4.7" depending on application
  • Pillow ball upper mounts included on select applications for direct steering feel and solid driver feedback
  • Camber adjustment available via the pillow ball mount on compatible applications, eliminating the need for a separate camber kit
  • Custom spring rates available for specialized racing setups

Backed by Ksport's 12-month limited warranty covering manufacturer defects, the Version RR coilover system is the definitive choice for serious road racers demanding the highest level of suspension performance and adjustability.

quick and easy

Excellent service. I called in Monday for a hard to find item which I had ordered from several other online shops who despite saying were In Stock online were not actually in stock at all and the orders were canceled after waiting a week to find out. They had the item in stock as listed on their website and shipped the next day. The price was the cheapest of anyone who actually had the item in stock by a substantial amount.

EASY AND FAST

Thanks for the great service, best prices, and fast shipping!!!
