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 center 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 (Φ46 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.
