*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.

Developer’s Comment
- This suspension has been tuned to suppress abrupt vehicle movements during performance driving, while providing a smooth and progressive damping feel that allows drivers to fully enjoy the cornering experience.
- Helper springs are used to maximize suspension droop travel as much as possible. However, for improved traction when exiting corners, we recommend the use of a mechanical LSD and a HICAS delete/cancel kit. (If the HICAS system remains operational, please ensure adequate clearance between the tires and wheels during suspension movement.)
- For drivers who prioritize ride comfort for street use or frequently drive on smaller circuits, lower spring rates are recommended. Conversely, for those seeking even greater body control and reduced vehicle movement, higher spring rates are also available upon request at the time of order.
■HIPERMAX R Technology
Newly developed oil SRF
We have developed a special oil with high viscosity that is resistant to heat dissipation. In addition, the damping starts from the very low speed range, providing reliable handling, good stability, and excellent feel.
※SRF:Super Response Fluid
Dedicated spring LVS
A newly developed dedicated spring made of high-strength wire material that is ideal for sports driving. It provides excellent response and a smooth ride.
※LVS:Low Vibration Spring
Spring Retainer
A retainer is standardly equipped on the top of the spring. No side force is generated, realizing low friction. It follows posture changes firmly and improves driving stability.
