Product Description

The Wilwood 140-11964 Forged Narrow Superlite 6R Big Brake Kit represents the ultimate front brake upgrade for 1993-1995 Mazda RX-7 FD3S owners seeking track-capable stopping power. Designed specifically for the lightweight, high-performance nature of the rotary-powered RX-7, this system features forged aluminum six-piston calipers that deliver massive clamping force while maintaining the low unsprung weight critical to the FD's legendary handling dynamics. The differential bore piston design with stainless steel pistons ensures optimal pad pressure distribution across the entire braking surface, providing consistent bite and modulation from street driving to spirited canyon runs and track days.

At the heart of this system are massive 14.00-inch two-piece rotors featuring Wilwood's SRP drilled and slotted design manufactured from Spec-37 high-carbon iron alloy. The 72 curved internal vanes create powerful airflow to rapidly dissipate the extreme heat generated during aggressive braking, while the drilling and slotting evacuate gases and debris for consistent pedal feel lap after lap. The two-piece floating design with aluminum hats not only reduces unsprung weight but also allows the iron rotor ring to expand and contract independently during heat cycles, minimizing warping and extending service life. Each rotor is finished with a black electro coat for corrosion protection and a professional appearance behind your wheels.

Installation utilizes a radial-mount design that bolts to factory spindles with included brackets, ensuring precise caliper positioning and eliminating deflection under heavy braking loads. The flared bell aluminum hats feature dual bolt patterns (5x4.50 and 5x4.75) for maximum wheel compatibility. The BP-10 brake pad compound is specifically formulated for high-temperature performance, making this kit ideal for track days, time attack events, and spirited street driving. Note that brake line kit 220-7010 is required but sold separately for a complete installation. Fully compatible with the RX-7's factory ABS system and master cylinder, this kit requires minimum 18-inch wheels and wheel clearance should be verified before ordering. Transform your FD's braking performance to match its renowned handling capabilities with this professional-grade big brake system.
