Hi,
Got mine new from the VW dealer. They fitted perfectly! No triming. Below are the part numbers by article. There is a complete kit as well but don't have the number on hand right now. Around 30 some for the whole.
8N0 721 173 A - frein (brake) +-8,41€
8N1 721 647 B - accél. (gas pedal) +-8,24€
8N0 721 174 A 01C - embrayage (clutch) +-8,41€
Prices were from 2008! No foot rest available for your left foot, at least for the left hand drive, without major modification. Got a RS4 foot rest but still need to modify it to fit.
Ltr, Didier
