    The only 1" cylinder I found was in the classic Girling style off an old Land Rover. The only downside was it took some effort to operate and tiring in traffic!! I've reverted back to standard.

    Is the clutch too light or are you not getting enough travel?
    If it's a travel issue, little you can do bar fit a different pedal assembly.

    Can you alter the ratio on the standard pedal by moving the point where the master cylinder connects?

    Phil would a 7/8" cylinder not suffice?

    Yes the travel is insufficient with a 19.05 dia piston

    Also the master cylinder is right up underneath the dash..... a slight GIT to get at

    The point where the cylinder connects is all welded up..... so I am trying to boge it up along the least line of resistance !!!

    7/8" may suffice..... but I think a 1" would suffice even more !.....even if I end up with one leg like Schwarzenegger !

    Got this one from Rally Designs on the way....... I will have the Grinder and hammer ready for when it arrives !!

    Reading back the earlier posts, the problem was lack of travel, so 7/8" would be the way to go, 1" is a bigger piston, so will reduce the travel...... think you may have your calculator upside down

    You need a lesson in pedal box fitting! Get hacking at that front bulkhead and fit a tilton or wilwood assembly and don't cut the pedals shorter or you are back to square one.
