I really dig your car and what you are doing with it... 'course this comes from a road racing nut so there you go
I like that you are using the 17s v. larger, heavier wheels... good mix of shorter sidewall on the tire while fitting the look of the vehicle and minimizing unsprung weight.
You mentioned cracking 4 cross-drilled rotors... I can believe this, but don't discount gas
slotting. Get them ball end milled with a few slots and this makes braking much better overall and unless someone screws up they should never crack due to that. Cross drilling creates stress concentrations around the holes and should always be avoided - at best consider rotors where the holes are cast into them, and even then they crack. But don't shy away from gas slotted rotors IMO.
Lastly, been various discussions about the color, but I love the gold color and there are a lot of vintage 60s-70s cars that look great in gold with black so I say stick with it. When I was 16 two cars I really wanted in my local area was a gold/black Plymouth Satellite and a gold/white top Galaxie 500 that both sold just before I looked at them, and my first road racing experience was driving this car (gold/blue) that my old friend Mark Behne restored:

so I am a gold muscle car nut I guess
