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. Its 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. *Dust Boot* Protect the shaft from the flying stones. *PNE Coating* 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.
