This product is designed for those who need or want to upgrade to a Wilwood 0.625" (5/8) or 0.75" (3/4 Larger Bore) Clutch Master Cylinder on their FC3S / FD3S chassis without cutting or drilling their firewall. Some transmission swaps require a larger bore clutch master cylinder and since there isn't a larger FC3S / FD3S one you can swap in, this is the best method. Additionally, this product is much more aesthetically pleasing than the ugly FC3S / FD3S cylinder and matches our Brake Booster Eliminator if you have it.
You can get it with either its own Billet Chase Bays Reservoir or a Clutch Feed Adapter hose to share fluid with the brake reservoir, like Mazda does stock. The black powder coated plate is made of 0.125" (1/8 or 3.17mm) steel and has the master cylinder mounting studs pressed and welded in. It uses the same thread type as stock, which is M8x1.25.
This does not fit with a stock clutch line but the Chase Bays Clutch Line has a Banjo connection which works perfectly with this product. Just use the Banjo Bolt that's included when you add the Master Cylinder to this order since the thread pitch on the stock clutch MC and the Wilwood MC is different.
Mazda Transmission, select the 0.625" (5/8 bore)
GM LS T56 / TR6060 or Dogbox, select the 0.75" (3/4 Bore)
Note:
