The Chase Bays Tilton Clutch Master Cylinder Firewall Adapter is the cleanest, most effective way to install a larger bore Tilton CMC (0.625″ or 0.75″) in your Toyota 86, Scion FR-S, or Subaru BRZ (ZN6 chassis)—without cutting or drilling your firewall.
Perfect for engine and transmission swaps that demand higher clutch fluid volume (such as GM T56, TR6060, or Dogbox), this adapter not only provides precise engagement and improved stroke feel, but also elevates the visual appeal of your engine bay. Built from black powder-coated 1/8″ steel with welded-in M8x1.25 studs, it ensures strength and ease of install.
Choose from three configuration options:
Adapter Only – For DIYers supplying their own Tilton CMC and fittings
With Tilton CMC, Clevis & AN Adapters – Saves time and ensures compatibility
Full Kit with Chase Bays Reservoir Setup – Includes separate clutch fluid reservoir, bracket, and EPDM hose for isolated systems (recommended for motorsport)
Please note: this product does not work with the stock clutch line, but is fully compatible with the Chase Bays Clutch Line. The only change is switching to the included 3/8-24 Banjo Bolt instead of M10x1.0.
