Stoptech Rear BBK Red ST-40/10 Slotted 328x28mm NSX 91-05

Rear BBK StopTech brake kit for the NSX (1991–2005) delivers shorter stopping distances and improved fade resistance for reliable deceleration under repeated use.

This StopTech Balanced Brake Upgrade maintains factory brake bias while improving pedal modulation and thermal performance.

• Balanced Brake Upgrades — maintain factory bias to preserve vehicle handling characteristics while enabling stronger braking response.
• Shorter stopping distances — front-to-rear system balance and upgraded components reduce overall stopping distances under the same conditions.
• Better modulation — stiffer StopTech calipers provide a more consistent pedal feel and improved control during progressive braking.
• Less brake fade — larger two-piece AeroRotors and upgraded pads reduce thermal degradation for more consistent performance on repeated stops.
• 2-piece StopTech AeroRotors (larger-than-stock) — slotted design and two-piece construction aid cooling and allow rotor float for controlled thermal expansion.
• StopTech Street Performance Pads — compound selected to match the system balance, offering a blend of street-friendly modulation and elevated stopping power.
