Ksport Circuit Pro 3 Way coilover kits provide the ultimate in adjustability for enthusiasts and professionals alike, who require maximum performance and durability. With years of engineering, testing and development, the Circuit Pro 3 Way coilover system has been perfected in virtually every facet of motorsports, ranging from drifting to time attack or circuit driving. The uncompromising range of adjustability on the Circuit Pro coilover System makes it possible to win at the track yet drive daily on the street as well. Each Ksport Circuit Pro coilover System has been dyno tested individually, and the results can be requested with the system at the time of purchase to aid in coilover tuning.

Maximum Durability and Consistent Performance

The key component to the Circuit Pro coilover System is its utilization of remote reservoirs that provide separate adjustments for rebound and compression, as well as nitrogen gas pressure. With over 11,664 possible settings provided by each Circuit Pro coilover System, it is possible to leave no stone unturned in the quest for ultimate performance from your vehicle’s suspension system. In addition to adjustability, the added oil capacity provided by the remote reservoirs increase the system’s ability to dissipate heat, which leads to improved performance over long periods such as endurance or tarmac racing, in addition to consistent performance throughout long heat cycles. These features, paired with 55mm Monotube shocks, ensure maximum durability and consistent performance.

Advanced Pillowball Top Mounts

These mounts allow for both camber and caster adjustment for the ability to dial in your suspension geometry to your needs. These mounts replace the stock rubber or plastic mounts to reduce flex and improve performance. The angle of the contact patch of the tire is changed improving handling when installed on the coilover.

Adjustable Lower Mounts

Most applications utilize an adjustable lower mount, which means height adjustability without losing suspension travel—a problem found in many coilover systems available today. Since mounts and most pieces in the coilover system are designed from 6061 billet aluminum, the components are lightweight, durable, and rust resistant.

Protection Against Corrosion

Steel shock bodies are electroplated with zinc to resist rust and protect from the elements. The shock or strut valving for each piece is matched accordingly to the spring rate, giving superior ride quality and reliability.

Superior Ride Quality & Reliability

The Ksport system uses a Monotube design in which the oil and gas are separated within the cylinder. When compared to twin tube construction, the Monotube design dissipates heat faster and more evenly, allows finer damping adjustments, and requires more expensive design process. Aeration and cavitation issues are a lot less common in a Monotube design, which results in a more consistent ride quality.

External Reservoirs for Independent Rebound and Compression Adjustment
Our Circuit Pro damper kits come standard with external reservoirs which allow adjustment of rebound, compression and nitrogen pressure independently. Possible tuning combinations are 11,664. NOTE: certain vehicles may only have front reservoirs if the vehicle does not have enough allotted space to fit a reservoir in the rear.

Advanced Pillowball Mounts
Standard issue on McPherson type vehicles are our advanced pillowball mounts which allow camber and caster adjustment for fine tuning your alignment specs. NOTE: not all pillowball mounts offer camber/camber adjustment.

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
Circuit Pro damper kits come with upgraded bumpstops to prevent the shock from bottoming out over uneven pavement or harsh road conditions.

Collars and Upper Mounts Made from 6061 Aluminum with T6 for Increased Hardness
Our 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 we call this a “hi-low kit”. In this case you will adjust ride height via the spring. Adjustable lower mounts on the rear shock aid in setting the correct shock stroke. 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 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.

Monotube High Pressure Design Reduces Oil Leakage
All of our 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 our coilovers are electroplated with zinc. We also include an anti-rust paste packet with our kits that can be applied to certain key areas of the coilover for added protection.

12 Month Limited Warranty
Circuit Pro coilovers come standard with a 12-month warranty which covers manufacturer defects.
