I recently bought a set of alloy pedals for my car as an upgrade for the interior. When I came to fitting them the brake pedal was the easiest of the three. The throttle pedal caused a couple of problems because the angle the original one is mounted at meant you could not access the rear of the original one to fit the screws and nuts supplied. So I used some self tapping screws, which having started the "thread" with them I then shortened before fitting with a dab of super glue on the thread to secure. The footrest, well that was another story altogether. It came supplied with 4 large self tapping screws to fasten it to the "carpet footrest". Problem is that the carpet footrest is not perpendicular to the seat, so to use the footrest as fastened to the carpet, means you have to keep tension in your leg rather than relax it, this caused me some considerable pain. So I acquired a piece of aluminium angle of 2"x 3" and on the wide side marked and cut it to the shape of the alloy footrest using the narrower side to fix to the carpet. I fixed a piece of ply to the narrow side to take up space between angle and carpet. Tried a "dry" fit with just 2 screws first then applied double sided carpet tape to both sides of angle before fitting Finally fitted alloy pedal to the angle. Then road tested.
