Master Cylinder Bore Size

[WallaceMFG]

I'm researching brake systems so I can start to price everything out and save money to purchase a brake booster. I plan on running a Hydroboost as my plan is to hopefully turbo my Chevelle sometime down the road.

I have C6 Vette front calipers in a box awaiting brackets, and I have LS1 rear calipers mounted on the car. My tires aren't going to be super wide, probably 245 front and 275 rear, hopefully 275 all around if I get my friend's wheels.

My main question is the Master cylinder bore size. I was hoping some experts could chime in and recommend what size I should get, I'm a little lost in the bore size/pedal ratio department.



I was looking at Wilwood MC/ prop valve deals, and they're a bit pricey but would look great under the hood.

Thanks!

I was told a hydro boost needs a bigger master. I am using a 1" with the z51 brakes with a vac booster I am putting on and will be going with 1.125 on dads car with a hydro boost

Most guys are running 1.125" bore MC's with LS1/C5/C6 brakes and hydroboost with good results.
