2006-2011 3 series Version RR Damper System by Ksport
Ksport Version RR coilover System is built specifically for road racing only. Aggressive rates and valving are chosen for maximum handling and performance with acute reaction and responsiveness. Integrated with 36 levels of damping adjustment, simultaneous compression and rebound adjustment, lightweight aluminum mounts, and pillow ball upper mounts on some applications. (Race use only.)
36 levels of damping adjustment allow you to fine tune the ride to your handling and comfort needs. The damping adjusts compression and rebound simultaneously for ease of adjustment. Pillow ball top mounts in the front and rear on some applications allow you to maintain vehicle manufacturer suspension geometry design. The pillow ball top mounts also allow you a more direct feel for solid driver response. Camber adjustment via the Pillow-ball Mount is available for certain applications, allowing camber adjustment without an additional ?Camber Kit.?
Most applications utilize an adjustable lower mount, which means you adjust height without losing suspension travel like some other coilover designs do. With the mounts and most pieces of the coilover being designed for 6061 billet aluminum the kit is lightweight, durable, and rust resistant. The steel shock body is electroplated with zinc to resist rust and the elements. The valving of each set is matched to the springs installed for unmatched ride quality and reliability.
The Ksport system uses a Monotube design in which the oil and gas are separated within the cylinder. When compared to twin tube designs the Monotube dissipates heat better, allows finer damping adjustments, and requires more expensive design process. Aeration and cavitation are a lot less common in a Monotube design, which results in a better ride.
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 = unbeatable performance on the track. 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 systems come with upgraded bumpstops to prevent the shock from bottoming out over uneven pavement or harsh road conditions.
36 way adjustable damping
All Ksport coilovers offer 36 levels of damping which allow you the ability to perfectly dial in your coilover system. Set damping to full soft for a nice comfortable cruising setting for normal driving.
Collars and upper mounts made from 6061 aluminum with T6 for increased hardness
Their spring perches, locking collars, top mounts and some lower mounts are made from high quality 6061 aluminum. Benefits include excellent strength and aluminum helps reduce weight.
Adjustable spring perch for height adjustment
Some vehicles have a separate rear shock and spring. In the coilover industry they call this a ?hi-low kit?. In this case you will have height adjustment via the spring perch and the lower mount of the shock. Vehicles with this type of set up can still go as low or lower than true coilovers.
Adjustable lower mount allowing maximum suspension travel
Most of their 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.
Camber adjustment on many models
Many of their applications that have pillowball upper mounts also have camber adjustability. This is extremely helpful when you need to dial in your camber for vehicle alignment purposes. This also eliminates the need for a separate camber kit. NOTE: Camber adjustment is not available on all models with pillowball upper mounts.
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 system helps combat noise while turning at slow speeds unlike other coilovers on the market.
Monotube high pressure design reduces oil leakage
All of their coilovers use Monotube shocks which dissipate heat better, allows finer damping adjustment and requires a more expensive design process compared to twin tube shocks.
Electroplated body for added protection from corrosion and rust
To help prevent corrosion and rust from the elements of nature, all of their coilovers are electroplated with zinc. We also include an anti-rust paste packet with our systems that can be applied to certain key areas of the coilover for added protection.
12 month limited warranty
Slide Kontrol coilovers come standard with an 12 month warranty which covers manufacturer defects.
