Code No. 80300-AF010C
HIPERMAX S, which has evolved damping force characteristics, durability, and aesthetics, offers the best "Driving Comfort" in the history of HKS suspension.
- The suspension is set to move flexibly while absorbing detailed impacts from the road surface. It has improved the ride comfort on the street by improving the followability on the road surface and reducing unnecessary movements by generating a solid damping force against road swells and movements during cornering.
- It can easily feel the vehicle's behavior thanks to the positive load transfer and can be enjoyed safe driving even in a limit range by suppressing sudden movements.
- You can fully experience the high-rigid SUBARU global platform and full inner frame structure.
- It has high durability of 60,000 km for three years by reviewing the 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
・Note that the suspension won't be able to stroke if the shock body length is 285 mm or less.
・The lower limit of the front is the value without the rubber seat and insulator.
・The alignment rear camber reference value is not adjusted, it is not described in the maintenance manual.
・MAX S series for VBH is launched. The stock electronically controlled suspension has the challenge of easy to give a soft feeling in comfort mode as well as a rough feeling on the road surface in sport mode. However, the suspension is set to move flexibly while absorbing detailed impacts from the road surface. It has improved the ride comfort on the street by improving the followability on the road surface and reducing unnecessary movements by generating a solid damping force against road swells and movements during cornering.
・It can easily feel the vehicle's behavior thanks to the positive load transfer and can be enjoyed safe driving even in a limit range by suppressing sudden movements.
・You can fully experience the high-rigid SUBARU global platform and full inner frame structure.
・It has high durability of 60,000 km for three years by reviewing the internal parts.
