Got bored last night and decided to mock up the driver's fender and hood:
Any doubt I had taking this direction with the car has been squashed. This is actually making me consider painting the car black now. Plenty of room with the new wheels and tires though. There's definitely going to some fitting involved but I only plan on getting it "close" so I can install the splitter and work on the radiator ducting. I'll let a body shop deal with the final fitting.
