*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

・Evan with the similar features between GR86 and latest BRZ, HKS tried to emphasize how different both cars due to the respect of each car’s unique character, it adopts in-house production with setting up which other manufacturers are hard to achieve.
・The stock suspension provides sharp handling because the damping settles quickly, and this product is designed to take advantage of this appeal, and also uses larger-diameter pistons to provide ride comfort with delicate damping settings.
・In order to suppress the damping force at the startup so that we tested many times to maintain the sharpness in the handling range and to suppress the damping force firmly at high loads.
・We also spent a lot of time selecting the spring rate, and repeated testing while changing the spring rate by 1K for both the front and rear.
・By loosening the damping dial, the ride quality becomes suppler, but we tried to set up the damping force adjuster so as not to cause unnecessary fluff during driving, this coilover is designed to be used over a wide range of driving conditions, allowing for sport driving on winding roads and tracks.
・The original rate can be changed, but the front suspension of rate increase is available with direct-wound springs. Rear suspension of rate can be changed to 5K, 6K, 7K, and 8K. 5K is available with direct-wound barrel springs.
・Please note that when installing on an AT vehicle, the front case will be lower due to the difference in vehicle weight, so please adjust the front case length before installation, referring to the test data. This will optimize the ride height balance and improve the ride quality.
