They are very simple. I just peel out the old rubber ones on the brake and clutch pedals (mine are bald on one side of the rubber from years of pressing against them) and slide the new ones on. The gas pedal, you would need to take the bolts out at the back (two bolts) and unloosen the back plate. You then unhook the spring and push the pin out of the plastic pedal. I use a small hammer and a piece of wood to knock the pin out. Once you get the pin off, just put the spring back on with the new pedal and push the pin back in. That's it....:29:Looks Great! How are they attached to the pedals? Do you know if there are WRX pedals like this for an AT? My gas pedal is the same, but the brake pedal on the AT is alot wider.
