Hipermax LS coilover kits are built from the same core components as the Hipermax Damper II coilovers but are tuned and valved for touring characterics. The Hipermax LS are specifically designed for ""Luxury-Sport Sedans"" where improved handling characteristics are achieved while maintaining a desirable ride comfort. Hipermax LS coilover kits are threaded shock body units that utilize aluminum spring perchs for full ride height adjustability (ideal to lower or raise height for various wheel sizes). Each kit also comes with upper pillowball mounts for improved steering response and secure mounting of the spring to the coilover (competitors offer this only as an option).
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
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 S-OC Type II
Bringing performance to the street while maximizing ride comfort was the goal of the Sustec Pro S-0C. For those who desire performance, comfort, and the overall benefits of coil over suspensions at an affordable value, we are now offering the S-0C Type II without helper springs.
Street-tuned Coil-Over Suspension System Kit engineered to deliver a comfortable ride.
Rubber Upper Mount (optional)
Optional upper mounts with rubber inserts absorb vibration and shock are a great upgrade over stock rubber upper mounts that improve handling and response.
Short Stroke / Short Case Design
S-S and S-0 are designed with a short stroke / short case shock absorbers that deliver superior handling without sacrificing strength or ride comfort.
Sustec Pro S-OC
For those who desire both high performance with maximum ride comfort, we offer the Sustec Pro S-0C. The short stroke / short case dampener delivers superior handling without sacrificing strength or ride comfort. Double-cylinder valving design allows for a full stroke within the extremely short case shock body. Low-pressure gases ensure smooth rebound characteristics for even more ride comfort.
Street-tuned Coil-Over Suspension System Kit engineered to deliver a comfortable ride.
Rubber Upper Mount (optional)
Optional upper mounts with rubber inserts absorb vibration and shock are a great upgrade over stock rubber upper mounts that improve handling and response.
Helper Spring
Smaller distinctly-colored helper springs allows for greater flexibility in determining the desired ride height. Prevents pre-load of the main spring when the height is raised as well as excess slack when it is lowered. This ensures a comfortable ride.
Short Stroke / Short Case Design
S-S and S-0 are designed with a short stroke / short case shock absorbers that deliver superior handling without sacrificing strength or ride comfort.
Sustec Pro SEVEN is an all new adjustable coilover suspension that features a wide array of all new circuit developed technology that has not been available until now.
SEVEN advances the technologies and greatest strengths of previous high performance Tanabe suspensions like the RR & DD even further. While similar in appearance, the SEVEN is completely different from any suspension currently available. The difference lies within the suspension itself and its highly unique internal construction and slide valve technology.
The new slide valve technology allows a great range of adjustability and function from both sides of the performance spectrum. (comfort to pure competitive motorsports 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.
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.

EDFC (Electronic Damping Force Controller) makes it possible for the driver to control the damping force by controlling a motor installed in the shock absorber while being seated in the drivers seat. Since the damping force can be manually controlled with ease to meet different situations, the driver can enjoy variations in the suspension setting.
Here is a great entry level tuned TEIN coil-over suspension kit Type Basic - that is a big step above the Sleeve Type Coilover kits with performance struts or shocks. These kits have all the high quality and high performance as all the high end Adjustable Suspension Kits, but are reasonably priced. All kits are ride height adjustable. The damping force (compression & rebound) is non-adjustable. Twin tube design allows the kit to be overhauled.
