JASS Performance brake stopper suitable for MX-5 NA / NB / NBFL. The brake stop prevents the fire wall from sagging and ensures that the pedal force is transmitted directly to the master brake cylinder and is not lost in the fire wall. This results in better braking performance with the same braking power and a better brake feel on the pedal. As usual with JASS Performance components, the brake stoppers are calculated and weight-optimized. The surface of the brake stopper is galvanized and black powder coated. It is mounted on the upper screw connection of the front struts, which means that it is not possible to install a strut bar.
