Looking at buying a set of BrakeMotive drilled/slotted rotors and pads in the next few months, but I've come across a small situation. I looked up the part for my truck, says for 5.3 engines or EXT which would mean a 12.8" rotor (same as the SS right?). But the price on these is $211, and the price on the SS kit is $230. I'm assuming it should be the same thing right, or are the calipers different and the pads aren't going to fit or something? Was thinking about spending the extra $20 if the SS rotor was a little bigger or something, but I thought I remembered reading that the 5.3's and EXT's had 12.8" rotors just like the SS. Can anyone clarify?
