Product Description

The HKS Hipermax S Coilovers (80330-AT010) are engineered specifically for the Toyota Supra JZA80 (MK4) with the 2JZ-GTE twin-turbo engine. With a stiffer front spring rate of 137 N/mm (14 kgf/mm) relative to the softer 78 N/mm rear, the kit is tuned to complement the JZA80's front-heavy weight distribution and deliver sharp, confident front-end response. The ride height range is generous - up to 92mm of front drop and 77mm rear - giving the owner wide flexibility from a modest street stance to a more aggressive, lowered setup. The kit ships with a mild factory-default drop of 31mm front and 13mm rear, ready for immediate use without corner balancing.

The Dual Preload Valve System keeps damping behavior smooth and predictable across all 30 adjustment steps, while the inverted front monotube design maintains rigidity and reduces unsprung weight for improved turn-in precision. Owners with REAS-equipped Supras should note that this kit requires removal of the factory hydraulic rear suspension system before installation - a common and well-documented process for JZA80 enthusiasts upgrading to aftermarket suspension.
