Duraflex B-Sport Style Rear Bumper Cover 1986-1991 Mazda RX-7

Duraflex B-Sport Style Rear Bumper Cover for 1986–1991 Mazda RX-7 (FC3S)

Give your second-generation rotary icon a classic, drift-inspired Japanese domestic market (JDM) aesthetic with the Duraflex B-Sport Style Rear Bumper Cover. Custom-molded specifically for the 1986–1991 Mazda RX-7 (FC3S) chassis, this complete rear bumper replacement updates the conservative, tucked factory rear fascia. Featuring a lower, squared-off aerodynamic valence and pronounced exhaust exit channels, it seamlessly complements wide-body panels or aggressive side skirt upgrades.

Constructed from Duraflex’s signature advanced material blend, this bumper cover overcomes the brittle downfalls common to standard aftermarket fiberglass parts. By infusing premium fiberglass matrices with specialized plastic polymers and flexible resins, the resulting component yields a highly resilient structure. It can flex slightly under impact or pressure, making it far better equipped to withstand track vibrations, scraping hazards, and daily road debris without instantly cracking or shattering.

Key Features:

• B-Sport Drifting Aesthetic: Brings an aggressive, low-slung look to the rear of the FC RX-7, dropping the visual ground clearance to match performance ground effects kits.

• Proprietary Duraflex Blend: Combines high-strength fiberglass mats with flexible plastic resins to achieve maximum durability and structural resilience against cracking.

• Signature Black Gel Primer Coat: Ships pre-treated with a protective black primer base layer, minimizing initial paint booth prep times and offering a uniform foundation for blocking, sanding, and color matching.

• Streamlined Aerodynamics: The extended lower apron helps clean up trailing low-velocity air currents behind the rear tires, reducing high-speed turbulent underbody drag.

• High Thermal Tolerance: Engineered to hold its structural shape perfectly without warping around hot high-flow performance rotary exhaust exit paths.
