I'm going to go ahead and be one of the few who dont exactly have a car they are basing theirs off of..
Everything that I will be doing will be batshit custom and borderline ugly for the sake of function.
For instance, here's an idea that hasnt yet screamed "DONT DO IT" to me (thanks again to the owner of the car for tolerating the shoop):
Still just an idea to work with, but who knows; I may end up working with it. It'll be either this or stick with pre89, but I'd prefer more frontal air for the various heat exchangers that I'll be using. Also probably would be a bit more square or less aggressive to fit the car better.
Also, I'm trying to experiment with NACA ducts on the front, specifically the hood, again for maximum function, but I still have to figure out what would look nice--or rather, not look like total shit.
