Another type of HIPERMAX S that employs the pillow ball spherical bearing at the front upper mount is newly added.
- The front upper mount employs the pillow ball spherical bearing and makes it possible to change the camber angle compared to the existing rubber bearing type of the HIPERMAX S. The direct handling feeling of the car from the pillow ball top mount brings more joy to driving.
- It reduces unnecessary movement by improving the follow-up performance on the road surface by moving the suspension flexibly. This will provide improved ride comfort on the street.
- It feels the car movement easily in sports driving by proactive weight transferring besides controlling the sudden movement in the limit range. It suits the beginner for sports driving. Employing the new parts inside of the dumper makes a wide-ranging setting.
- 3-year warranty included for the highly durable product with the reconsidered internal parts.

*1. Height from road surface to fender arch.
*2. Height at factory is the data tested at HKS with the setting of Full Kit. (HKS' recommended setting.)
*3. Adjustable range (However, the lowest value may not be road legal.
Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive.
Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.)
*4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.)
Caution). Actual data depends on each vehicle.

Point
・Arm locks when front case length is less than 212 mm.
・The product is set up with the matching approach to characteristics of SILVIA. By making the suspension suppler, it tracks better with the road surface, which reduces unnecessary movement and improves the ride comfort on the street.
・In sports driving, the car's movement can be easily felt by actively shifting the load, and the control can be safely enjoyed by suppressing abrupt movements at the limit range. It is also recommended for beginners to practice sports driving.
・Since SILVIA is a highly sporty rear-wheel drive vehicle, we put effort on rear stability and have set the rear suspension to a weak understeer setting. If you want to move actively to oversteer, please tighten the rear dial.
・New internal components allow for a wide range of settings with a large amount of dial variation.
・Due to the installation of insulator springs in the front and rear, it is easy to adjust the vehicle height.
・High durability of 3-year/60,000 km coverage has been achieved by reviewing internal components.
・Please experience the evolved HIPERMAX!
