ok here we go, I have been doing some research but why not ask for some help. I want to upgrade to a nicer pedal set but OEM. I am trying to find out especially about the dead pedal and the gas pedal. I had a friend who as a b7 rs4 and the clutch and the brake pedals just come off and can be swapped but the gas pedal looks like a complete piece. I see on many web sites the use of rs6 pedals (only auto) avail, is there a difference between the gas pedals on a b7 vs a b8 can or can I use only the gas pedal from and rs6 auto on a b8 6mt?????
the dead pedals between the rs4 and the rs6 look almost the same but you can order either one seperate so thats not much of an issue, the gas pedal is the question at hand.
