When we mounted our Wilwood brake and clutch pedals, the sloping firewall kept us from putting them as far back as we would have liked. The distance between the drivers seat and the pedals was just too close to be comfortable. Thankfully, the pedals allow the master cylinders to simply be flipped over for overhead mounting. We created a frame for the pedals out of some fairly thick sheetmetal and square tubing and welded it to the rollcage at the correct height. Of course, this is just one more area where we are going to have to rework the brake lines.
