Yes, I am using a Wilwood 3/4" master cylinder pusher type. After getting back home to Tulsa and out of almost 100 degrees of pit temps in Omaha last weekend I believe I found the problem. The alignment apears to be ok but I bottomed out hard enough to bend the rod and break the piston spring. I think I was coming out of a turn at about 90+ mph and hit my clutch hard (very hard) shifting on the straight a way trying to catch the car in front of me. Rookie mistake...
I will pick up another master cylinder today and after installing and bleeding the unit I will install a stop pad behind my pedal. Hopefully, this won't happen again because I was having "too much fun" when I had to quit.
Just a side note: Mike Moss at HP Motorsports in Omaha took the time on Saturday afternoon (after his shop was supposed to be closed) to help me rebuild a master cylinder so I could get back on the track. Great people that do quality work. These guys can build anything and I hope if any of you are in need of quality work fairly priced you give them a call or check out their web site:
