The Ksport Version RR Road Race Coilovers for Infiniti Q50 were carefully designed for road racing. The system features aggressive spring rates and shock valving for maximum handling and performance with acute reaction and unparalleled responsiveness on the track. Integrated with 36 levels of damping adjustment, simultaneous compression and rebound adjustment, lightweight aluminum mounts, and pillow ball upper mounts on some applications, the Ksport Version RR Road Race Coilover Kit is the ultimate suspension system for serious road racing.
Built for Racing
Strictly made for track racing only, not recommended for street use. Aggressive spring rates and shock valving combined with 20-30mm shorter shock stroke results in an unbeatable performance on the track. With your choice of our proven spring rate settings or your own custom rates, the shocks will be valved specifically to what you select.
Upgraded Shock Bumpstops
Version RR damper kits come with upgraded bumpstops to prevent the shock from bottoming out over uneven pavement or harsh road conditions.
36-Way Adjustable Damping
Featuring 36 levels of damping adjustment these Road Racing Coilovers allow you to perfectly dial in your coilover system for both handling and comfort. In addition, the damping adjustment alters compression and rebound simultaneously for more effective and user-friendly setup changes.
Aerospace Quality Aluminum Components
Most pieces in our Coilover systems, including mounts, collars and spring perches, are designed from 6061-T6 Billet Aluminum resulting in lightweight, durable and rust resistant components. Steel shock bodies are electroplated with Zinc to resist rust and protect from the elements. In addition, kits include an anti-rust paste packet that can be applied to key areas of the coilover for added protection.
Adjustable Spring Perch for Height Adjustment
Most applications utilize an adjustable lower mount which means height adjustability without losing suspension travel. Users can easily achieve desired ride height without worrying about bottoming out the shock. For vehicles that have a separate rear shock and spring, or a “hi-low kit”, height adjustment is available via the spring perch and the lower mount of the shock. This allows vehicles with this type of set up to still go as low, if not lower, than true coilovers.
Adjustable Lower Mount Allowing Maximum Suspension Travel
Most of our coilovers feature the ability to adjust your ride height without affecting the shock and spring travel. This way you can set your desired ride height without having to worry about bottoming out the shock.
All Metal Pillowball for Added Strength and Responsiveness
A step up from our Kontrol Pro coilovers, the heavy duty all Steel Pillowball adds more strength and better steering response. You may experience slightly more noise with this type of Pillowball which is completely normal when compared to OEM suspension where noise is reduced by using rubber parts. Our patented new Top Nut and Bearing Kit helps combat noise while turning at slow speeds unlike other coilovers on the market.
Monotube High Pressure Design Reduces Oil Leakage
The Ksport Version RR Road Race Coilover systems utilize a Monotube design, with oil and gas separated within the cylinder. When compared to twin tube construction, the Monotube design dissipates heat faster and more evenly and allows for finer damping adjustments. Aeration and cavitation issues are a lot less common in a Monotube design, resulting in a more consistent ride quality.
Camber Adjustment on Many Models
For enthusiasts seeking the ultimate in adjustability, Ksport’s advanced upper pillow ball mount is available on many applications, giving the option for separate camber and caster adjustments. This allows you to easily dial in your camber for things such as vehicle alignment while also eliminating the need for a separate camber kit. *Note: Camber adjustment is not available on all models with pillowball upper mounts.
Pillowball Top Mount for Increased Steering Feel
On many applications, Pillowball top mounts in the front and rear allow you to install and setup to OEM specifications. Ksport’s patented upper pillowball mount offers the same level of adjustability and performance but allows for compliance that is often required from high-demand strut applications. In addition, our pillowball upper mounts combat noise, increase steering feel and response and on many applications, offer camber adjustment, eliminating the need for a separate camber kit.
Dust Boot to Protect Damper Seal
Dust boots are standard on all coilovers. We also integrate the bump stop inside the dust boot. This is more efficient and is less likely to crumble to pieces and deteriorate like other designs.
12 Month Limited Warranty
Version RR coilovers come standard with a 12-month warranty which covers manufacturer defects.
