3/4" master cylinder?

Not that simple. You must look at the net force. A few degrees do not eliminate the ratio increase, but seal life is reduced from what it would be. How much depends on how far we offset. Every brake pedal starts at less than 90 and may end travel past 90. It is a band aid and there are better ways.

I pulled my pedal box last night (wasn't bad except the stupid seat in the way..) going to modify it tonight if i feel up to it.. Right now barely pressing the pedal puts it over 90* going to move the top mounting hole forward a bit to give it a little more angle (and still keep the starting point/brake light switch in the same place)
