I would think that this difference might be enough to cause the pedal to hit the floor though, so maybe I actually need a larger bore master cylinder, but with the same pedal ratio as my mom's car.

When I go back to NC again, I plan on playing a few "swap the parts" games to see what happens.

Thanks!

P.S. Tobin, are the Kore3 rear brake brackets to fit C6 Corvette Z06 rotors and calipers to a Ford 9-inch available yet? I didn't see them on your website.

A larger bore MC is going to generate less pressure, not more. If you have the opportunity to pick up a caliper pressure gauge, they can be useful in situtations like these where it sounds like you're not getting enough pressure in general. Let us know what you learn from swapping parts though as that could definitely shed some light on the situation.

As for rear 9" kits, those have been available for a while now. They're listed on our site at the following link in all of the various configurations (305mm C5/C6, 330mm C6 Z51, 340mm C6 Z06) with and without drum-in-hat parking brakes (DIHPB): http://www.kore3.com/products.php?cat=12

Even better, Scott put up a thread with his KORE3 C6 Z06 DIHPB kit installation with lots of pictures: https://lateral-g.net/forums/showthread.php4?t=14127

True, but coupled with the different pedal ratio, it might be the combo I need. I think that just going with a different pedal ratio might make the pedal hit the floor before the master cylinder is used up.

As for the pressure gauge, I think I might have a set... hmm, some digging is in order.

Thanks!
