This billet adapter and larger bore master cylinder kit will allow you to do a simple bolt-in installation of the Tilton clutch master cylinder. Available in 3/4" and 13/16" bore, this larger bore master will allow for better clutch disengagement.

This clutch master cylinder kit with billet adapter fits LHD or RHD Mazda RX-7 (FC3S). The rx7 RHD kit comes with the Grannas Racing "RHD" angled reservoir. This will also fit other Mazda's that share the same master cylinder bolt pattern as the FD3S chassis.
