HKS HIPERMAX R Coilovers for Toyota Supra Mk4 (A80)

The long-awaited HKS HIPERMAX R Coilovers for the Toyota Supra Mk4 (A80) have arrived—engineered to deliver exceptional performance without sacrificing ride quality.

Designed specifically for the 1993–1998 Toyota Supra MKIV, the HIPERMAX R combines HKS’s newly developed Super Response Fluid (SRF) with the Low Vibration Spring (LVS) to achieve an outstanding balance of razor-sharp handling, high-speed stability, and refined street comfort.

A newly designed upper spring retainer aligns spring load and damping forces coaxially, eliminating spring bending loads while absorbing torsional stress. This design improves damper response and allows the LVS spring to perform consistently whether on the street, track, or spirited canyon driving.

Revised internal damper components provide a wider adjustment range, giving Supra owners precise suspension tuning with 30 levels of damping adjustment. Front and rear spring insulators are included to simplify ride-height adjustments on the MK4 Supra chassis.

Building upon the proven technology found in the HIPERMAX S, the HIPERMAX R for Toyota Supra A80 introduces three exclusive, next-generation technologies for maximum performance.
