AUTOEXE Mastervac Brace for Mazda RX8 (Series 1 & 2, 2003-2012)

Brace the brake booster area to reduce bulkhead flex, giving a firmer, more consistent pedal and improving feedback during repeated hard stops.

$360

Under heavy braking in Mazda RX8 Series 1 & Series 2 models (2003–2012), the firewall can flex slightly as you press the pedal, and this AUTOEXE Mastervac Brace provides rigid three-dimensional reinforcement around the brake master cylinder to remove that vagueness and delay from the system.

  • Reinforces the brake master cylinder assembly to prevent firewall flex under hard braking
  • Delivers a firmer, more direct pedal feel that makes modulation easier
  • Improves the initial response time of the braking system, shortening the gap between foot input and braking force
  • Constructed from high-strength steel to maximise rigidity and long-term durability

You will feel a much more direct and confidence-inspiring brake pedal, with clearer modulation and control during spirited road driving or track sessions in your RX8 (2003–2012).

For a cohesive brake and chassis package, pair this brace with the AUTOEXE Motion Control Beam Front & Rear on Series 2 (2009–2012) cars and the AUTOEXE Strut Tower Bar for improved overall chassis rigidity.
