Code No. 80300-BF001P
Front Pillow has been added to the S-series upper-mount for WRX S4(VBH)!!
■Features
- The popular WRX S4 HIPERMAX S now features pillow upper mounts on the front, allowing for camber angle adjustment.
- Our high-performance shock absorbers with large diameter single-cylinder pistons provide a high-quality ride even with the car lowered.
- The damper has been set to move smoothly, absorbing small bumps in the road while generating a firm damping force for wavy roads and cornering turns, improving road compliance.

*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.

■Other Features
- The HIPERMAX S is characterized by its dual preload valve system and wide range needle. Laser marking is used for the exterior, and spring insulators are standard equipment.
Dual PVS
The preload valve system has been further evolved and now features a dual preload valve. This cuts the damping force at high speeds and reduces unnecessary movement.
