Mechanical brake booster?

[evilC]

the floor was lifted by 50mm infront of the pedals to creat a platform about 12-15" deep (there is a sloping front edge). the height of this was determined by finding the most comfortable position with the heel on the (raised) floor and the ball of the foot on the pedal pad. The floor raising suits my size 8 (US size 9) feet and I can pivot my foot between throttle and brake as well as comfortably heeling and toeing. That 50mm height also allows me place pull M/Cs under the raised floor should I eventually go down the route of putting in a brake balance bar a la AP
AP also set their floor position up about 40mm from the pedal pivot point so I can't have got it too wrong. Besides, I first drove a VW beetle around 40 years ago and found then that the pedals were set so high that I had to take my feet off the floor to press them. That to me meant that I had less control over the clutch action but more importantly the braking effort. Bouncing around the local lanes needs all the control you can muster and maintaining your heel on the floor is paramount for that. Many of my friend at Loughborough Car Club have modified their rally cars in this way even though their pendant pedal boxes are not so chronic as the VW one - it was them that gave me the idea.
