Back Bay Customs Master Cylinder Adaptor

This is a key component in all of our kits and consists of two parts. The robust mount is machined from solid 5/8” steel providing the strength necessary to prevent flexing at the high torque junction and properly clocks most aftermarket master cylinders to the Bosch iBooster used ’18-’20 Honda Accord. The aluminum insert is precisely machined to fill the gap between the recessed iBooster actuator rod and most popular master cylinders like Wilwood, Baer etc. Includes all mounting hardware.
