I am looking into buying new rotors for my CSX project. I have converted the car to use full '91 11" vented disc setup from an R/T. Have reman calipers with metal pistons, Hawk HPS pads ready to go. I'm not much interested in x-drilled or slotted rotors and it doesn't look like they are even available anyway. I'm wondering though, is it worth it to buy new name brand rotors such as Brembo or Wagner vs cheap parts store replacements from Oreillys or NAPA? The cost for the name brand replacements is significantly higher (sometimes 2x), but there is no real indication that I can find that they are in fact higher quality. If I new they were higher quality and wouldn't surface rust from sitting so easily like some cheapies I have bought in the past, then they might be worth it.

For example, front rotors for a '91 Spirit R/T application:

21.99 - Brake Best Select rotors from Oreillys
31.99 - NAPA 'premium'
52.99 - Wagner rotors from Oreillys
61.28 - Brembo rotors from www.buybrakes.com

What do you guys think???
