Point

HKS has developed it for a sporty drive. We have tested over and over with professional driver in TC2000 and Fuji Speedway short course for all other settings.(Tire size 1: F:245/40-17&R:255/35-18, Tire size 2: F:225/40-18&R:255/35-18) The test result of rate is 16k/16k, but with newest technology, the ride is mild and have perfect control. With smooth movement will prevent from traction slip and with the dial adjustment, you can move weight as you want to. It has a special characteristic of weight movement and better grip. We have done the setting with AD08R high grip tires. If you don’t use such a high grip tires or circuit attack, we recommend 2k down for both front and rear.
