Code No. 80300-AF010CP
Front Pillow has been added to the S-series upper-mount for WRX S4(VBH)!!
- The popular WRX S4 HIPERMAX S now features pillow upper mounts on the front, allowing for camber angle adjustment.
- With the stock electronically controlled suspension, the ride feels fluffy and unstable in comfort mode, while in sport mode, small bumps in the road are very noticeable. Our high-performance shock absorbers with large diameter single-cylinder pistons provide a high-quality ride even with the car lowered.
- The suspension 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.
- By installing our error canceller included in the set, you can avoid the error that appears when you remove the stock electronically controlled suspension.

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.
