HKS 80330-AZ002 Hipermax S Coilover Full Kit for Mazda RX-7 FD3S

The HKS 80330-AZ002 Hipermax S is a full coilover suspension kit engineered specifically for the Mazda RX-7 FD3S (1991/12–2002/08) powered by the 13B-REW rotary engine. As the evolution of the legendary HKS MAX IV GT series, the Hipermax S represents over nine years of advanced suspension development, consolidating the best characteristics of HKS street-oriented coilover lines into a single, all-around performance platform.

Designed to deliver the ideal balance of spirited handling and everyday ride comfort, this full kit features adjustable ride height and damping force settings to accommodate everything from daily street driving to spirited canyon runs and occasional track use.

Key Features:

• Single Tube (Monotube) Damper Design: Maintains separate gas and oil chambers for stable, consistent damping force with a larger piston diameter for superior control.
• Inverted Shock Absorber (Front Strut): Spreads lateral forces over a larger area for increased rigidity while reducing unsprung wheel weight for enhanced handling response.
• Dual PVS (Dual Preload Valve System): Suppresses unnecessary damping force at higher piston speeds, delivering a meaningful improvement in ride comfort without sacrificing driving performance.
• WR Needle (Wide Range Damping Adjustment): Improved needle jet shape expands the damping force adjustment range with 30 clearly defined steps, including softer settings optimized for street use.
• Advanced Bump Stop Rubber: New bump stop geometry targets earlier contact to progressively absorb load and suppress abrupt changes in body movement, reducing body roll while maintaining ride comfort.
• PNE Coating: High-durability protective coating provides superior corrosion resistance for long service life.
• Strengthened Rubber Upper Mount: Absorbs small road vibrations while maintaining firm mount performance for improved NVH and handling precision.
• Machined Aluminum Top Mount: Lightweight, high-quality aluminum construction reduces unsprung weight and enhances exterior aesthetics.
