The Ksport Circuit Pro 3-Way Coilover kit for Mazda 3 is our top of the line system for enthusiasts and professionals alike who require maximum performance and durability. With years of engineering, testing and development, the Circuit Pro 3-Way 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 system makes it possible to win at the track while also being suitable for daily driving.
The key component to the Circuit Pro system is its utilization of remote reservoirs which 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.
A variety of external hardware components are available on the Circuit Pro 3-Way Coilovers to completely customize the system to your vehicle. When fitting this kit to your vehicle, upper mounts are available in rubber form, pillowball or Ksport’s award winning advanced pillowball mounts that offer camber and caster adjustment. To further ensure complete customization and performance, each system has been dyno tested individually and the results can be included upon request with the system at the time of purchase to aid in coilover tuning.
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.
Built for Racing
The Circuit Pro 3-Way Coilover systems were specially designed for track 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 Bump Stops
Circuit Pro damper kits come with upgraded Bump Stops to prevent the shock from bottoming out over uneven pavement or harsh road conditions.
Added Oil Capacity
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.
Individually Dyno Tested
Each Ksport Circuit Pro 3-Way coilover System has been dyno tested individually and the results can be included upon request with the system at the time of purchase to aid in coilover tuning.
55mm Monotube Shocks
55mm Monotube shocks allow for added oil capacity and increased cooling efficiency, which ensures maximum durability and consistent performance.
36-Way Adjustable Damping
Featuring 36 levels of damping adjustment these coilovers allow you to perfectly dial in your 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.
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.
Adjustable Lower Mount Allowing for 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.
Most of our applications for vehicles with MacPherson type suspension will have the ability to adjust camber via the top mounts. This is extremely helpful when you need to dial in your camber for reduced tire wear or add more negative camber to aid in aggressive wheel and tire fitments. NOTE: Camber adjustment is not available on all models with pillowball upper mounts.
Monotube High Pressure Design Reduces Oil Leakage
The Ksport Circuit Pro 3-Way 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.
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, allowing vehicles with this set up to still go as low, if not lower, than true coilovers.
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
Ksport Circuit Pro 3-Way coilovers come standard with a 12-month warranty which covers manufacturer defects.
