Default Oh yea another thing

If you call Wilwood they will tell you to get a 7/8's for a manual system. That is correct if you are using a tandem master. It will not work with duals and a ballance bar. Been there and tried that.

You are pushing 2 masters so you will need to split the leg pressure by 2. I have run a number of calculators on this and trial and error testing...how I arrived where I am now.

I have 1 inch, 7/8, 3/4 and 5/8 masters now in my possesion. LOL

With a 6:1 to 6.2:1 ratio, you are looking at 5/8 or 3/4 on front. Size the rear one step bigger( all of this depending on your calipers. If you are using SL6's and SL4's in the rear I am right on). That will get you close on the bias and use the ballance bar to tune from there.

My piston size is 1.62, 1.12, 1.12 on the front and 1.75, 1.75 on the rear with 13 inch rotors.
