The N1 Evolution is the newest generation of our track engineered flag ship N1 suspension. All N1 dampers feature large piston, monotube design using a threaded base for height adjustments without compromising shock or spring travel. Every year, we gather incredible amounts of suspension data from our direct involvement in many different racing series. This specialized data goes directly into our sports parts development to provide the customer with the same cutting edge suspension technology we use on all of our race vehicles.
In many respects, circuit competition is regarded as racing in its purest form. APEX has been at the forefront of this arena for years, building time attack vehicles for competition in top level events and racing series. We have worked side by side with many of the worlds most talented drivers and top racing teams. Every race serves as an invaluable opportunity to refine our suspension setup and take note of what effects various changes make to a race car. The N1 Evolution CIRCUIT damper was developed using the same principal setups that we would use in one of our own competition track cars. This is the ultimate no-nonsense coilover for those looking to shave precious seconds from their lap times. It has a piston diameter of 52mm.

HKS Hipermax Damper II coilover kits provide the ultimate in suspension tuning with 30-way dampening, threaded dual-chambered shock assemblies and perches for height adjustment, upper Pillowball mounts for improved steering response, and tempered springs.
The all-new Hipermax Racing Sport (RS) coilover suspension kits are the first Hipermax line to be engineered as a truly global suspension system. HKS suspension engineers spent over a year developing the Hipermax RS, testing on various race tracks throughout the world, auto cross events and street testing in both Japan and the United States.
The result of all this testing and development is a coilover suspension system that has been precisely valved to dramatically improve handling at a competitive track level, yet still be comfortable even on the harsh road conditions in the United States. HKS was able to achieve this versatility by using an F1 inspired single tube structure coupled with an oversized piston and dual oil and gas chambers. A shortened cylinder body allows suspension travel to be maintained when the car is lowered. The Hipermax RS also features HKS trademark 30-way dampening and rebound adjustability that is adjusted simultaneously for easy tuning. The included anodized aluminum upper pillowball mounts improve steering response, traction and offer a more direct feel to the driving surface. On certain applications camber can be adjusted on the upper pillowball mounts. All HKS Hipermax RS coilover suspension kits are built in-house at HKS Headquarters in Japan.
Stage 4 Coil Over Suspension H&R is the originator of the true coil over just a threaded tube and some sort of spring, but an actual threaded strut and shock body with a specifically designed spring. H&R coil overs are engineered for street and occasional track use, H&R Coil-Overs feature a fully-threaded shock body (not an imitation sleeve-over) that allows you to precisely dial in height adjustment to achieve optimum weight transfer, or simply get the aggressive look you've been looking for. Featuring H&R's exclusive dynamic damper technology, each shock is engineered to work in harmony with a progressive-rate spring, together creating a finely-tuned suspension system.track wh
Whether your vehicle is set up for everyday street driving, weekend racing at the track, or strictly for show, the Skunk2 Racing adjustable coilover kit is your solution. Each kit comes complete with hard-anodized CNC-machined threaded aluminum sleeves, CNC-wound SAE 9254 racing springs, and mounting hardware that allows up to a 3-inch drop (sometimes more). Our dual-locking perch design has proven to be the most reliable method for securing the spring perches. The key to the coilovers performance and unsurpassed ride quality is the advanced spring design technology that allows the use of higher spring rates with minimal compromise to ride quality.

TEAS stands for 'Tanabe Electric Active Suspension and is the counterpart of the new Sustec Pro FIVE & Sustec Pro SEVEN suspension. This compact unit is the brain behind the highly sophisticated new Tanabe suspensions. TEAS is a fully programmable dampener controller that allows for dampening force to be automatically adjusted while driving. TEAS accomplishes this by connecting and using the signal from the vehicles Speed Sensor.
Remote dampening control from within the vehicle is not a new concept by any means. In fact, many Japanese vehicles from the 1980's including the FC3S RX-7 and MA70 Supra had buttons to change dampening ; Unlike other controllers that are simply an update of this older technology, TEAS is a much larger step towards highly digital advanced suspension control and tuning through its speed sensing
TEAS active dampening control is uniquely possible due to the use of the specialized valving of the SEVEN, in conjunction with TEAS; slim, high speed actuators. These actuators change dampener settings in 1/100ths of a second, which is necessary as TEAS can continuously change settings at different speeds.
Sustec Pro FIVE is an all new adjustable coilover suspension that features a wide array of all new circuit developed technology that is similar to Tanabe's Sustec Pro SEVENS.
Sustec Pro FIVE delivers broad performance for the track to the streets. Featuring 12-way(16-way with TEAS) front & rear adjustment, FIVE allows drivers to fine tune height, dampening and rebound based on street conditions and driver preference.
The new slide valve technology allows a great range of adjustability and function for street and track use.
When used with the new TEAS electronic active suspension controller, the wide range of dampening force is accessible through the touch of a button, and is fully programmable to automatically adjust dampening rates according to the speed you drive.
