Point The ride quality improvement under low speed range at a low speed and on rough road surfaces and vehicle handling stability improvement were focused when developing this product. For this product, the inverted type strut suspension is selected for both front and rear dampers. Compared to the stock suspension, the inverted struts enhance the rigidity remarkably and support the handling stability improvement. The offset upper mount designed specifically for S660 enables to obtain the sufficient stroke amount even after lowering a vehicle so improvement of the ride quality and vehicle handling stability is implemented together. The front damper is not using the stock-body length adjustable system to utilize the original performance. The spring change is available; however, the spring rate must be carefully selected since the vehicle height changes considerably depending on the spring rate. 【MAX IV GT】 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.
