The new Max IV sporty suspension. Awesome sporty drive with great control and comfortable ride in the street. It’s perfect for daily street drive with style and performance. You and your passenger can have a comfortable ride even with a low-down.
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”
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 because of the optimized oil pressure characteristic. We mainly adopted this to the rear damper that can have a better driving experience.
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 or circuit.

*1. Height from road surface to fender arch. *2. Height at factory is the data tested at HKS with the setting of Full Kit. (HKS’ recommended setting.) *3. Adjustable range (However, the lowest value may not be road legal. Even within the adjustable range, car body, arm etc. may contact. In such case, it will be hard to drive. Damper oil leakage or any other problems caused by low ride height setting from the factory setting will void the warranty of the product.) *4. Drivable range that there is no contact of car body or arms etc. (However, change of tire/wheel size may cause a problem.) Caution). Actual data depends on each vehicle. |

Point |
We have set it for the mainly street use with the F SPORT type. First, we set the vehicle height low for cool look. You can adjust the damper setting because it’s a height adjustable lower bracket type. We try to keep the stock’s stroke and drive feel. But there is some rolling, and N mode and S/S+ mode has some wrongness. We adjusted for these problems and have even smoother driving experience. Also we adjusted and set the weight allotment for springs and dampers for best steering and less rolling. But still have the great feeling for human sense. We have set enough stroke as the stock to reduce the uncomfortable reaction from road surface. We also checked with electronic device for stability and comfortable drivability. Please set the dial at 15 for beginning and drive for a while. Then if you prefer more comfortable ride, set it at around D20 or set it D00 for sportier ride. * We have checked with TRD stabilizer, so you can also use it to reduce the rolling. * When lowering down by using special wheels, we recommend not changing factory set case length because it will interfere with front upper arm and also inner front and back stay and tire. We also advise not to use bigger front tire. |
