Between sanding Bondo, spraying primer, and dying the interior parts, I've been studying Napaonline.
If I want to use Mazda calipers, the NB4886041 is 11.88" x 0.87", and $ 42 ea. But I think I want more. I think the next step, playing it safe, is NB4886777, which is just 11.7", but is 1.03" thick, for using the Camaro calipers I have. That's $ 46 per rotor. Either of those are likely to require having their center holes enlarged. And they're both 5 on 4.5, so I'd have to drill 3 new holes in each to make them 4-lug. That's not difficult.
If the 11.7s prove an easy fit, there are NB48880014, also 1.03", but 12.02" and $ 53 ea. Or if I want Mazda calipers and 4-lug without drilling, UP880192 is 12.01" x 0.87" for $ 49 ea.
But then we come to the other spec of cast rotors. The height. Napa gives these specs also, but if you have to make caliper brackets anyway, all that matters is if the height is too shallow for your calipers and your wheels.
If I like what I end up with, I'll offer copies of my brackets.
If I just wanted the biggest cheapest rotors, I found some 12.72" x 1.18" for $ 36 ea. Dunno what low-cost calipers they'd like.
Anyway, that's where my mind is while I'm nearing the deadline for Maaco.
