Part Number: AXL-3-305-10
Drop front: 0.5-2.75"
Drop rear: 0.5-2.75"
Spring rate front: 7K
Spring rate rear: 8.5K
Price: $1599.99

Further Info:

The CorkSport 2007-2013 Mazdaspeed 3 and 2004-2013 Mazda 3 coilovers are back and better than ever! Featuring 15-way adjustable damping, 2 inches of ride height adjustability, refined spring and damping rates, and front camber adjustment, the CorkSport coilovers will suit your needs whether you’re looking for some better handling on the street or a full autocross setup. Check out the full details below!

Balanced Ride and Handling:
The front struts of the CS Coilovers use an inverted monotube design. What this means is the gas and oil portion of the strut is rotated 180° of a typical strut. While this may seem strange, it offers superior strength and reliability. When coupled with spherical pillow ball mounts instead of the OEM rubber mounts, you get a coilover that is ready for some serious driving

Performance Focused:
The CorkSport Coilovers use 7K front springs and 8.5K rear springs. By increasing the rear spring rate more than the front, you gain more neutral handling characteristics (less understeer) and a better ride. This setup has been carefully chosen to provide great handling without being too harsh to daily drive. We even went through frequency analysis to determine if our spring and damping rates were suitable for the street!

Appearance Boost:
While handling benefits are the main goal of the CorkSport coilovers, you get a great appearance boost as well. Lowering a car lowers its center of gravity, reduces body roll, and obviously, looks great. The CS coils offer approximately 2” of ride height adjustability, so you can really dial in how your car handles and looks. Minimum ride height drop is 0.5-0.75” lower than stock.

Adjustability for Street and Track:
Both the front and rear CS coilovers offer 15-way damping adjustability. This offers you the ability to tune your ride to your comfort and handling goals. Both the front and rear damping adjustments can be easily accessed, with no disassembly required! The front end also offers camber adjustability to really dial in your handling or wheel fitment. Up to three degrees of negative camber can be achieved.

OEM Fitment:
The CorkSport Coilover kit is a direct replacement for the OEM suspension system. This means the install is quick, easy, and does not require the use of spring compressors. We even went with studs instead of bolts for the front shock tower mounts to help with install. No permanent modifications are required however; you can choose to modify your strut towers for frequent camber adjustment.

Long Lasting Durability:
All components in the system are designed to stand the test of time. All steel components are powder coated while all aluminum pieces are anodized so you can be sure your coilovers will last as long as the rest of your car.

Everyday Drivability
Research on the racetrack has helped us develop the Fortune Auto 500 Series into a great all-around shock absorber. Using high quality components that meet our strict standards allows us to optimize comfort, reliability, and longevity.

Occasional Track Use
Digressive piston technology allows for stiff low-speed compression/rebound force. This gives more control of driver inputs such as roll, dive, and squat. However, at fast stroke speeds (i.e. high speed bumps) the suspension becomes supple in response to bumps and irregularities in the road for maximum control.

Further Info:

State-of-the-art motorsport technology for proven performance on the streets. The independently adjustable compression and rebound damping allows for custom driving set-ups. The exclusive KW patented system has dual-level valves to provide the adjustment of the rebound damping (comfort) and the compression damping (driving dynamics) in the low-speed range. High-speed settings for driving comfort are preset by KW engineers.
• Independently adjustable damping technology (rebound and compression damping)
• "inox-line" stainless steel technology*
• Individual height adjustment
• Infinitely adjustable rebound damping
• 14-level adjustable compression damping
• Unique, independently functioning damping power adjustment
• TÜV-tested adjustment parameters
• High-quality components for long life
• Comprehensive documentation for ease of use

Based on vehicle specifications, the rebound damping is adjusted by a spindle at the end of the piston rod. Mainly, the traction phase (rebound) controls car body vibrations and influences handling and comfort in the low-speed damping range. By using the traction phase adjustment, the vehicle can be fine tuned to the requirements of the driver. Moreover, driving behavior can be regulated from comfortably rolling to sporty and tense with improved road holding characteristics.

The compression phase adjustment is carried out at the lower end of the shock absorber via KW’s patented multi-purpose valve. The large number of pre-set parameters on this valve allow for a wide range of adjustment for individual use. The unique low-speed compression adjustment distinguishes this technology from any other. In this compression range, the driving behavior of the vehicle is drastically influenced. An increase of the damping power supports the vehicle already during compression and therefore avoids rolling and pitching. The directional stability is significantly improved.

Further Info:
Ksport Kontrol Pro Fully Adjustable Coilover Kits provide the ultimate in suspension technology for your vehicle, both on the street or at the track. 36 levels of damping adjustment allow fine tuning of the damper to suit both handling and comfort needs. The damping adjustment alters compression and rebound simultaneously, for more effective and user-friendly setup changes.

Pillowball Top Mounts
Pillow ball top mounts in the front and rear on some applications allow the vehicle to install and setup to OEM specifications. Ksport’s patented upper pillow ball mount offers the same level of adjustability and performance but allows for compliance that is often required from high-demand strut applications.
On applicable models, the pillowball upper mounts offer camber adjustment, saving the need for a special, separate camber kit. For enthusiasts seeking the ultimate in adjustability, Ksport’s advanced upper pillow ball mount is available on some applications, giving the option for separate camber and caster adjustment.

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.
The Ksport Kontrol Pro Coilover system has been designed with professional road racing in mind, offering extremely high value and performance for any application.

Features:

36-Way Adjustable Damping
All Ksport coilovers offer 36 levels of damping which allow you the ability to perfectly dial in your coilover kit. 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
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.

Camber Adjustment on Many Models
Many of our 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.

Pillowball Top Mount for Increased Steering Feel
Many of our applications for vehicles with McPherson type suspension will have pillowball upper mounts. Our patented new bearing design helps combat noise while turning unlike many other coilovers on the market. Steering feel and response is improved with pillowball upper mounts.

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.

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
Kontrol Pro coilovers come standard with a 12-month warranty which covers manufacturer defects.
