baer rotor alternative....?

[debo]

Hello all!
I have a rear baer kit with a 12" x .81 rotor with a lt1 caliper. Id like to decrease the rotor size to fit into a drag setup. Baer lists a 11.35 x .81" rotor as the next size down. Is this a stock gm rotor or a 11.5" camaro rotor thats been cut down? Cant find any answers. Id like to find a cheap rotor for mock up purposes.....



Thanks,
Daren
