Thank you Greg! you are good for something on this forum

Another thing that needs to be taken into consideration is mounting of pedals & calipers.. The stronger the mount.. The less defelection you will get & the firmer your pedal will feel..

Ron will get me the bore diameter on the calipers & we will do a calculation of what will get us in the ball park.. It is always different from our calculation due to how you want pedal feel..

Pedal RATIO is important - for brake pedal TRAVEL -- and the multiplier of effort. 7:1 ratio will travel MORE and produce more pressure per effort than will a 6:1 pedal.

It ain't rocket science. The other #2 thing people forget about or make poor choices about is what pad they choose --- because a super hard race/autocross pad will feel crappy on the street regardless of all of the above.
