Point

Mr. Manabu Orido (also known as Mr. Supra) set a 1.682s faster time on racing track at Fuji International Speedway with only suspension upgrade.
This suspension utilized a conventional shock absorber rather than factory electronically controlled one and a vehicle is easier to understand and to control according to the driver’s intention.
Using the high rate spring provides a smooth ride without too stiff feeling and at the same time helps to translate a feedback from tires.
Using HKS traditional inverted type at the front. To ensure the stroking amount and height adjustable range, HKS designed special outer cover.
Adjustment type pillow upper allows to adjust the camber angle.
The billet aluminum upper plate is used at the rear. This is for weight saving without losing the necessary strength.
The straight wound spring is used at both front and rear allowing to easily change spring rates.
Note: Error canceler is required due to removed factory Electronic Control Shock Absorber.
