Using mustang rotors for 4.5" bc

Are the raybestos rotors the strongest rotors available? Seems like a rotor with a solid hub would be better than the web design the raybestos uses??
Is there any concern about the balance of the rotors once the diameter is machined?
Thanks

I think you're right, there's little doubt a solid hub would be much stronger, but it looks as if not just Raybestos, but all brands of the Mustang rotors that would work have the vents. That's a main reason why I swapped the spindles, and went with the 11.75" rotors.
I don't think anyone has complained in this thread about the balance. If it's an issue, you could take it to a shop that balances the wheel on the hub. Those are probably getting scarce, though.
