(Pic 3) Start by undoing the dead petal pop up screws(2), the door jam screw(1), and the pressure flaps on the door sill. Remove. Next, unlike me who didn't look online to get help for this, and was lost for 5 minutes, grap the clutch/brake pedal covers and pull from bottom up and out ; they come off easy. Throw away.(Pic 4) You should be here now. The STi clutch/brake pedal slip over the metal pedals, and attach with a metal bracket that sits above the old petal.. It is attached by 2 bolts. Look at the directions for the pic. By the way , the bolts have thread lock on them, and are hard to put on or off. Here comes the harder part. The gas pedal is attached by a pin , this plastic petal piece, and a spring. I couldn't for the life of my get the pin out...If somebody does., or knows how , awesome, but it didn't pop out for me.
