Yea it could possibly be, beacuse i tried my mates civic type r one on and it too has a 1mm lip all the way around at the bottom. i'll get me one of them i think.
Oh and one other question have you also had the dredded gearbox failure on the golf yet??? They normally go around 60k, mine went, not a happy moment and quite expensive aswell £1600 for a new box and a clutch and labor charges! But i still love it too bits tho!!
Love the colour of your golf tho mate, just needs decking! Just looking at it reminds me of why i like rs6's sooooo much! sweet car mate!
