how do those attach?
You drill 3/16" holes in the existing metal pedal base. It comes with stainless hardware and lock nuts to attach them. I really just wanted the gas pedal cover only, but now that I have them the rest of the covers are pretty nice. The clutch and brake covers are larger than stock as well.
I made the gas pedal cover adjustable. I have 2 sets of holes for it if I want the gas pedal even closer when I get to the track. In my mountain road testing it felt pretty good where it is though.
