*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
The kit was tested with ADVAN A052 Tires(235/40R18) at Fuji Speedway Racing Course.
By taking advantage of the BRZ's character, that it runs through corners with slight understeer, We have designed a damper that can create the ideal movement that the driver envisioned.
This damper could satisfy both track beginners and advanced users who are aiming for breaking records. Even with one notch, you feel the change of movement strongly. With this kit, you can enjoy it from street driving to track.
By adopting the bump rubber that HKS has been researching for many years, it creates the stable feeling when cornering. It allows the tires to gain stable traction without suddenly losing grip.
For those aiming for breaking record, the front tires should be about 0.5-1.0mm toe out with slight camber, and the rear tires should be about 0 to 0.5mm toe in. We recommend about 5 to 10 clicks of damping force adjustment at the front and rear.
This kit provides the best riding comfort in street driving. The new springs provide a ride quality that makes you forget this is a damper for tracking with high-rate springs.
The damping balance between compression and extension has been optimized. Even through driving through a great gap, you won't feel the uncomfort of bouncing, which high rate spring brings up.
HKS BODYKIT TYPES are installed, and the match with aerodynamic automobile parts installed is also confirmed.
