so I'm killing time at work so I decided to CAD out my pedal box today, and try and figure out what I'm trying to achieve here. I already decided after looking at this model I'm going to mount the hole assembly (master cylinders and all) on a moveable deck so I can adjust the pedal distance. Any other features I could work into this design?

The middle pedal needs to hinge at the top to push on the master cylinder, unless you are going to mount it backwards.

yeah, i'm going to reverse mount all 3 MC's to make it easy.

Curious on how high your foot plates will be from the chassis floor. (working on that part myself). I was going to go this route myself untill I desided it was easier to get my wife a booster seat. I was going to use the upper plate in a groove and heavy spring loaded tapered pins to lock in place at a series of holes in the edge brackets.

my pedals are roughly 5" inches off of the floor, I have big feet, so its probally best to measure your foot and put that into the cad like I did, height and width.

How about mounting a brake switch up there (obviously for the brake sender) better than the pressure devices most of us use IMHO. A lot of people tend to drive very close to the derrere just to get a better look, in which case a simple depress of the brake will ward them off. Obviously the pressure device would have to be operational to switch by which time he cold be sat in your boot!

Check the Tilton and AP Racing websites for drawings of their pedal sets.
