Strut Tower Bar and Master Cylinder Brace for Mazda RX-7 (FD3S), Right Hand Drive

Improved Racing designed this lightweight, solid aluminum strut tower bar for maximum engine clearance. These strut bars feature an optional adjustable brake master cylinder brace which solves the common firewall flex issue in the RX-7 for improved brake feel and performance. The brake master cylinder brace is compatible with both the factory and 929 brake master cylinders.

Fabricated from solid 6061-T6 aluminum and MilSpec Type II anodized in black, this strut bar is the strongest and most durable on the market.
