Hipermax S is HKS's full four corner coilover set for the RB26 Skyline GT-R, built on an inverted monotube strut with the company's WR Needle valve giving 30 steps of damping at each end, the rear pair adjusted remotely by cable and dial rather than by reaching into the boot. Spring rates are 88 N/mm front and 78 N/mm rear on 19.8 N/mm helpers, and the height adjustable lower brackets set fender height from 626mm to 695mm front and 631mm to 699mm rear on the BNR34, or 622mm to 691mm front and 628mm to 690mm rear on the BCNR33. Dual PVS valving, PNE coated bodies and aluminum upper brackets with rubber mounts finish the kit, which is rebuildable and carries a three year HKS warranty.
