The result is the Hipermax IV GT Spec-A, with revised spring rates and dampening. Using the expertise of Arai-san, a stiffer spring rate but longer length paired with softer dampening creates a more comfortable and natural ride without the loss in performance (similar to the coilovers used in Rally Racing). Likewise, they address the GDB's issue of understeer to improve overall performance!
