HKS Hypermax Max IV SP Coilovers for Toyota Supra MKV '20+

This suspension utilized a conventional shock absorber rather than factory electronically controlled one
and a vehicle easy 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.
> 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.

Many various developing tests have been carried out on the track at Fuji International Speedway
and on the street.
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.

The stock front strut cannot adjust the camber angle due to it needs to be inserting the lower strut. To avoid this, using adjustment type pillow upper can make the adjustment about 1 degree from stock mount position instead. At the circuit driving, increasing negative camber decreases understeer. In addition, we used a steel plate to ensure strength.

Using HKS traditional inverted type at the front. Of course, the strut type must ensure the high rigidity but the inverted type does not necessarily mean the use of the large main shaft modifications to ensure  the rigidity. This allows us to achieve smooth stroking without changing gas pressure. To ensure the stroking amount and height adjustable range, HKS designed special outer cover.

The rear upper mount used billet aluminum with laser marking and also did weight saving modifications without losing strength. Placed the adjusting dial at the bottom part of the upper mount. We  recommend to jack up the vehicle when adjusting damping force, however on our test vehicle with installed ADVAN Racing GT19 inch wheels we could access adjustment dial through the wheel.
