I was looking to get some Power Slot rotors for my 2000 SE.
But they only have front rotors. But I see that the 2000 Grand
Prix has the same size front rotors. And Power Slot does have
a rear rotor for the Grand Prix. So my Question is: Are the rear
rotor on the 2000 Bonneville SE the same size as the rears on
a 2000 Grand Prix?

I'd hope not, the bonnies are alot heavier than the GP'*, but you never know.

But the fronts are the same size.

The fronts are not the same size!!! The front (and rear IIRC) rotors are 1" smaller than the Bonneville rotors. The ones you see listed for the GP that are the same size as the bonnie rotors are an upgrade. Lots of people upgrade to the bigger brakes. (12" instead of 11" IIRC) I am also pretty sure the rears are 1" smaller too.

I'm pretty sure you can just order powerslots for a Bonneville anyways, but I'm not positive. Did you try www.3800performance.com ?

Not have nothing for Bonneville in brakes. And all the other sites only
have front rotors. I want all 4 rotors slotted and no rusting.
