The Ksport Asphalt Rally Infiniti Q40 Coilovers are designed specifically for Asphalt Rally Racing and competition. This system features extended stroke, heavy-duty internals, and simultaneous compression and rebound adjustment. Large diameter pistons inside the shock allow for added oil capacity for increased cooling efficiency and carefully selected spring rates and shock damping settings for each application help to stabilize the vehicle and easily absorb bumps caused by uneven roads.
36-Way Adjustable Damping
Featuring 36 levels of damping adjustment Ksport Asphalt Rally 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.
Inverted Steel Shock Absorber for Increased Response and Heat Buildup
Inverted shocks are standard for some applications that have MacPherson type suspension (non-wishbone). Inverted shocks move the gas/oil chamber farther away from the knuckle and braking kit reducing heat transfer. This design also reduces unsprung weight which helps improve handling and responsiveness. *Note: On inverted shocks the damping knob is at the bottom of the shock. Each kit is supplied with a flexible damping adjustment knob for easier access.
Large 55mm Shock Bodies
55mm Shock Bodies are used on kits that have inverted shocks. This allows for added oil capacity for increased cooling efficiency. They also perform better under stress situations which make them especially well-suited for track racing.
Heavy Duty Steel Lower Mounts
Strengthened steel lower mounts are standard on vehicles using MacPherson type suspension. Vehicles with wishbone/multi-link type suspension have standard aluminum lower mounts as seen in our other coilover kits.
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.
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.
Monotube High Pressure Design Reduces Oil Leakage
The Ksport Asphalt Rally system utilizes 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 pillowball 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.
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.
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.
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.
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.
