The Serpent SER903758 Brake Pulley Adaptor S989 is made to match the Viper 989 GP brake assembly. It supports consistent braking action so you can focus on lap time rather than component issues.
As a dedicated adaptor for the Viper 989 GP, this part secures the pulley connection and reduces unwanted movement. That stability translates into more repeatable braking points and cleaner corner entry.
Clean mating surfaces before fitting the Serpent Brake Pulley Adaptor S989 and check alignment carefully. Tighten fixings evenly and recheck after a few runs to confirm the adaptor remains seated correctly.
