HKS Hipermax R Coilover Full Kit - Toyota GR Supra DB42 2020-2026

HIPERMAX R sits at the top of the HKS coilover range, supplied as a full kit covering all four corners of the B58 powered DB42 GR Supra. The front is an inverted strut damper that preserves stroke at lowered ride height, the rear separates damper and spring and uses a machined aluminum upper plate to save weight, and both ends carry spherical bearing (pillow ball) upper mounts with 30 step damping adjustment. Spring rates are 14.0 kgf/mm front and 20.0 kgf/mm rear. Ride height adjusts from -15 mm to -45 mm at the front and 0 mm to -71 mm at the rear against stock. Because the kit replaces the factory electronically adjustable dampers, an error canceller is required and is not supplied in the box.
