Product Description

The HKS 80330-AF002 HIPERMAX S is a vehicle-specific full coilover suspension system developed for the Subaru Impreza WRX, WRX STI, and WRX Sport Wagon applications using the GDA, GDB, and GGA chassis. HKS specifies this application for EJ20 turbocharged models, with the GDA and GGA covering Model A-G vehicles and the GDB covering WRX STI Model A-D vehicles.

The system uses 69 N/mm front springs and 49 N/mm rear springs, with 220 mm front and 250 mm rear barrel-type springs. HKS lists a baseline ride-height change of -36 mm at the front and -22 mm at the rear, with adjustable ranges of -16 to -68 mm front and -5 to -86 mm rear. HKS notes that the published height data for the GDA and GGA applications is based on the GDB WRX STI reference vehicle.
