Mine is kind of a hodgepodge mix currently. I originally went with Racecraft's kit, it comes with a Strange master. The problem for me was that the master ended up hitting my turbo header, not Racecrafts fault, so I had to put a shorter master on to clear and I put one from like an Aerostar on there iirc and it now clears. I seen how good the Maximum pedal was with Rick's car so I bought one for mine as well. It's a really nice piece as is pretty much the case with anything I've ever seen come from Maximum. All that being said lol, if I was to do this all over again I would just get the complete setup from Maximum and call it a day.
The master that comes with the Racecraft kit is a 1.125 bore.
