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 (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.

Front: 12k

  1. Worth it!

    By Kirby March 26, 2020

    Much better coilovers than my previous Fortune Auto DSG Limited Editions (9k springs). HUGE improvement in ride quality and feel. I was slightly alarmed that I couldn't lower my car as much as I had planned, but it turned out to be the perfect ride height. Front sway bar end links were VERY difficult to get bolted on.

  2. Great product.

    Don't expect to slam your vehicle on the ground with these coilovers, that's not what they are made for, but you can lower it enough to get a very aggressive stance. These coilovers feel great on the road with the damping dialed out, and can be stiffened up quite a bit for aggressive driving. They provide great road feel and help keep the car nice and flat in the corners
