What size M/C are you guys using. I am putting a car together & I am not sure what to get. Mostly going to run 1/4 mile dirt.

I guess I should have stated what sizes & why. Anyone else have an opinion.

More often than not, you are going to want more rear brake than front. The sizes listed above along with a balance bar will accomplish that. The rears have a little further to travel as well.

But also when using the smaller m/c's the pressure is higher but the volume is lower, so don't go below 1" on the front.
1" front and 7/8" is pretty much what everyone runs that I know of. Its what I run and I think my clutch is 3/4" but don't try to use that small on the brakes!!!!
