Rotor & Caliper Upgrades?

My stock front calipers are sticking and at least one of my rotors is warped on my '99 LS, so I want to replace them with an upgrade. I'm riding on stock 15 inch rims so I don't know what size rotors I can fit in there. Anyone know what the stock rotor size is and what the largest size rotor/caliper combo I can squeeze into my rims? I'm in the process of performance upgrades so I'm gonna need more stopping power. What should I do. Also should I replace all four corners or can I get away with just the fronts for now? Thanx.

I could be wrong.. But i don't think you can get a rotor/caliper combo without getting bigger wheels. You can get different rotors though. I Would suggest slotted rotors, cross drilled ones reduce the structural integrity of the rotor and they could crack on you. And if your rotors are warped then it sounds like you do some hard braking. So slotted might be the way to go, Plus you will need some better pads. Ceramic is nice if you are on a budget. If not the get some hawk pads or some other good brand.

i think AEM make a brake/rotor upgrade combo for OEM wheel size.
