which rotors are better?

I would buy zinc plated...

Mine were zinc and did not rust at all other than a little surface rust that rubbed off immediately in the first 2 seconds of driving. They look real cool. Solids don't look as cool but are much better performance as they do not give up all that surface area. Been there done that and studied the book and internet debates on it. Either way they look awesome.

I got mine from rotor pro's. It is zinc plated brembo rotors and they are slotted and cross drilled. so far they are fantastic. i believe they make it for GT calipers also...But don't know. Price were fair also. good luck

get the zinc plated. mine aren't and look like hell.

I know I'm going to get flamed about this but cross drilled are a waste of money unless you are race car. You run the risk of cracking more plus I have noticed they seem to warp easier. I've been running Brembo slotted/cross drilled rotors on the front and yes they have been awesome at the track but they really set you back some bucks. Noise wise, seems like mine make a funny harmonic sound under hard braking but maybe I'm just hearing things. All in all, slotted/cross drilled are great but not worth the price. IMO, buy just slotted or even blanks from autozone and the money you save buy better pads. The difference you will see between slotted and slotted/cross drilled will be very little if driven a lot on the street.

With that being said, I have ordered from stang suspension before and the customer service was pretty good. Only problem I had was something he could not control and that was a back order of rotors from Brembo. I know this doesn't answer your question but just a little food for thought.

mine were the summit brand drilled ones. i liked them, but i took them off because i upgraded to bullitt brakes last year.
