pedal ratio is detirmined by dividing the length of the arm [the pedal pivot to the pedal pad center] by the distance from the pivot to the master cylinder pushrod hole. the FARTHER away from the pivot point, the lower the ratio. you maybe able to fix this by just drilling a new master cylinder rod attaching hole in your pedal. the thing to watch for, however, is that you don't bind the rod in the master at full stroke. hope this helps.
