Subaru Impreza GDB 2005-2007 HIPERMAX 4 GT Coilovers by HKS

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 to protect the shaft from the flying stones. PNE coating provides 5 times better durability over standard galvanizing.

This prevents build-up around the threads of the adjustment areas allowing for easier height adjustment. The new M shaft design of cylinder shaft increased the cylinder shaft size to have a firm damping even at a little stroke range because of the optimized oil pressure characteristic.

HKS mainly adopted this to the rear damper that can have a better driving experience. Newly designed needle has been used to revise the very low speed and middle and high speed dampening which is key to a comfortable ride. In order to reduce unsprung weight, bracket, ride height adjusters and lock nuts are made from aluminum (Not for all vehicles).

30 levels of dampening adjustment allow fine tune adjustment for street or circuit.
