NA/NB Miata Brake Master Cylinder Brace

Miata firewalls flex under heavy braking, which gives you a soft pedal and takes away from the braking force at the wheels. This brace bolts into the factory shock tower location on the NA and NB Miata and pushes back on the brake master cylinder so the firewall can't move.

It works alongside the OEM NB1 strut tower brace. It does not fit with any other OEM strut brace, including the NB2 brace, and so far I haven't found an aftermarket strut brace that works with it. With the stock air box, the box needs a small trim to clear.

It does not work with the dual booster master cylinder setup found on some NBs. Reach out if you're not sure what your car has.

These are kept in stock.
