If you didn't get a Darkhorse, you missed out on a better engine, better transmission, tighter track suspension, better aero, unique chassis tuning.
Again, seems like you're just sour grapes that you missed out big time
I'd start with tires, than move to brakes.
Your brakes are only as good as the contact to the road. If you're planning on tracking the car, then having beefier rotors and larger calipers will certainly help with heat soak to the metal, as well as distributing the brake pressure across the pad...
yuck. Good to know.
If its any consolation, Ford Motorcraft filters are actually the best in the business, funny enough. Their bypass valve is in a good location, they hold a lot of oil, and they filter media isn't glued together poorly
A lot of companies are willing to accommodate your needs if you just email, btw.
If you see a design or style you like, but its Audi or Nissan only, or something, then just send an email. A little communication goes a long way. Same goes for shift boots and stuff.
