I think attention to details is what makes or brakes a car and you are very careful with all the details. So job well done! For the brakes you might consider some APRacing ones (very very good and cheaper than Brembo)And for wheels I would consider the BBS range, especially the RS-GT ones which I think look great on a VW Golf (a bit expensive though)!
Michelin Pilot Super Sport is not overall a soft compound, only the outer part app. 15% is a soft compound. The rest is treadwear 300, so soft it aint ;)
I will have the smoothed grill by the end of January. I already have the Carbon bonnet without the notch in it to fit. You need to do it Stephen, it looks soooo smooth in that photo.
