Acura RSX Brake Master Cylinder Brace

Our USA made master cylinder brace is strategically designed to maximise the rigidity of your RSX's brake pedal setup. By reducing firewall flex, the addition of our master cylinder brace will improve the responsiveness and predictability of your brakes.

Benefits of our Master Cylinder Brace:

The Simple Speed master cylinder brace effectively reduces flex in the firewall under high brake pedal forces. This reinforcement creates a more responsive brake pedal feel, increasing the predictability of pedal inputs. Whether you are chasing tenths on track, or just looking to improve the driving experience of your RSX, our brake master cylinder may be the perfect investment.

fitment is good

It fits a spoon strut bar for reference. It does have fitment issues with any airbox that will require cutting.

Haven't tested it on track yet but feel free to reach out again in a month or two for an update.
