As for size they are exactly identical with the exception of bolt pattern so I dont see why anyone would even bother with them.... just get a set of OEM ones from the local auto zone and you will be happy, the ones on ebay, are drilled and they can crack especially if you were to use them with the bigger GTO calipers, because you increase clamping forces and those holes when heated stretch out and stress the metal around it and pretty soon they can fail and if that happens at a higher speed you are a dead man...
Also the holes were for decreasing weight and allowing for room for the gases created by the pads to escape but thats a thing of the past the new pads dont gas up so unless you care for looks I would recommend that you stay away from those...
Another thing with sloted rotors is that you loose gripping area where the slots are so its as if you decreased the size of your rotor...
Best braking will be out of Solid Vented rotor, with GTO calipers and C5 pads... Hawk or whatever brand you like...
I got the cheapest money can buy from autozone... C5 Z06 pads and they grip like no other, much much better then the previous GTO pads..
