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 (FD3S). 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.

This kit includes the following:

1. Tilton master cylinder (3/4", 13/16" bore size available)
2. Reservoir, Cap, clamp, 3AN union fitting
3. Billet adapter bracket
4. Hardware/studs for installation
