I use the Razo adjustable gas pedal and the stock brake pedal in my old track car (the red '95). I really like the setup. The bottom of the pedal flares to the left, but the top is not that much wider, so you still have to rotate your foot some, but are not as likely to brake and accelerate at the same time by accident as my OMP race pedals will do, even in my racing shoes.
I will try and take a picture tonight.
