Master Cylinder Upgrade??

Are you replacing the MC because it went bad or are you trying to correct a problem? 1 1/8" bores are usually used with power boosters and smaller bores with manual brakes. High pedal leverage can allow larger bores, but there are other factors to consider for correct bore.
The Summit 1 1/8" Corvette MC says it has a deep brake rod hole (normally used for manual), yet it says it is for power brakes.
If you have high pedal pressure, you might consider a 1 1/16" or 1" MC.

the 1.1/8 come with a spacer to use for power brakes and you remove it for manual. We have used many of these on manual brakes and they work fine.
