Sorry for the late up date guys, have only got to run the car twice in the last couple months. I ended up getting my brake ducts done finally, kind of a PITA with all of the charge piping, intakes, and oil cooler plumbing. I had to use the side vents, which I wasn't keen on doing. I decided that blocking them off completely will help with high pressure in the fender wells.
I used the Stillen mounting plates on the spindles, which fit well and made hooking up to the center of the rotor easy. I made the block of plates out of aluminum, and welded some bead rolled tube on to clamp the ducting to.
I plan on getting ARP studs in so I can run 10mm spacers in back. Im also working on rear downforce options that don't include a big wing.
Don't mind the munched splitter, I caught some debris.
