People need to ask why Vorsteiner stopped making the GTR hood.
My guess is that the demographic of M3 owners has changed, and that "current" M3 owners don't see value in a $2000 hood. A person that can afford to buy a $55k car is going to have a different disposable income versus a person that can afford to buy a $25k car.
My personal view on this is that HPF needs to decide what THEY want out of designing and selling their own hood. Do they want to make a market statement with a functional design? Do they want to adapt to general market consensus to sell volume?
If I was managing this project, I would probably bring in a big name aero guy like Andrew Brilliant to do both. Chris...he's worth calling.
