Post these on Norotors. The V8 guys have been needing an alternative to the Hinson version.

Several people have bought hinsons and have had fitment issues with certain master cylinders that these do not.

and does it work with the "Jamar Performance Master" for the FC. Is the shaft is long enough for the clutch pedal puck up, or does it need an extension piece like the willwood one?

Thanks - Havoc

Yes it will work with our jamar performance MC. On our setup we simply used the mazda mc shaft in our jamar unit. With the jamar adjustable mounting plate we were able to make that work with no extensions.

Hey Chuck, you should try our JAMAR Performance Master Cylinder Stu Kelly Motorsports


Otherwise any 3/4-7/8th size bore aftermarket master cylinder will also work better than stock.

Just a word of warning. It The "JAMAR Performance Master Cylinder" doesnt work with RHD cars. and the threat on the shaft is different to the FC thread.

Other than that a great looking kit. (I should have got more measurements before buying it...)
