hey ken I have spotted a slight variation from originality in the underside pic of your car
there are indeed some variations from stock.
some things you might have noticed:
-G60 front brakes with ducts, you just need bigger brakes
-Golf mk4 rear calipers
-supersprint exhaust collector, OE exhaust manifold was cracked so time to upgrade.
-the OE fuelltank has the heat shield on the tank, mine is now mounted up seperately (late model).
I'll update this thread.
