HKS FRS/BRZ/86 Hipermax MAX IV SP Coilovers
The sport model to have a comfortable drive even in the winding road.
This "MAX IV SP" is the ultimate sport model for such a high grip radial tire. It will transfer the feelings straight to driver all kinds of information such as tire, road surface condition and traction. It’s a perfect street sport model suspension for people who love to drive fast but still want comfort.
*Single Tube Damper Design*
Mono tube dampers allow for more accurate and stable control and adjustment of dampening. Lower ride height and centre of gravity gives a more stable ride.
Protect the shaft from the flying stones.
Using this special surface coating provides 5 times better durability over standard galvanising. This prevents build-up around the threads of the adjustment areas allowing for easier height adjustment.
*M Shaft (F46 normal type)*
With the new design of cylinder shaft since the HIPERMAX M-1, MAX IV increased the cylinder shaft size to have a firm damping even at a little stroke range by optimizing the oil pressure characteristic. We mainly adopted this to the rear damper that can have a better driving experience.
*Adopted Pillow Ball Upper Mount*
For more accurate and sharp steering.
*New Design Needle*
Newly designed needle has been used to revise the very low speed and middle and high speed dampening which is key to a comfort ride.
*Reduction of Unsprung Weight*
In order to reduce unsprung weight, bracket, ride height adjusters and lock nuts are made from aluminium. (Not for all vehicles)
*30 Step Damping Force Adjustment*
30 levels of dampening adjustment allow fine tune adjustment for street, circuit winding roads, highway, or the weight of the vehicle.
