[QUOTE="GT Premi, post: 16230564, member: 121775"] Speaking from personal experience, I don't recommend putting larger rotors only on the rear, unless you're going to also add a brake proportioning valve or do something to adjust brake balance. I have rotors from Full Tilt Boogie Racing. I opted for the larger rear rotors. I didn't think/consider that the larger rears would throw off the balance as much as they do. When I get on the brakes at high speeds, the rear end will get squirrelly on initial bite. And that's with a 13.1" rear rotor. A 13.8" will be worse. That's nearly the same size as the front rotor. The rear end hasn't actually come around on me [yet], thank goodness. Pads; I have the Duramax Gold pads front and rear. They're very good at not producing a lot of dust, and they stop pretty well WHEN THEY GET WARM. Cold stopping is not good with these pads. I almost rear ended somebody trying to come to a stop on a cold day from 25MPH. I went for the normal amount of pedal force and [i]nothing was happening[/i]! I had to stab the pedal to the ABS threshold. That was a real eyeopener with ceramic pads. They work better when they're hotter. You'll notice that, if you ride the brake pedal, the stopping force increases as the pads heat up. They'd probably do pretty well on a track. During cool/cold seasons on the street, you need to keep it in the back of your head that initial stopping power isn't going to be very good. That said, they seem to be very long lasting. I think I have 20K miles on these pads, and they appear to only be about 50% used up, if that. Brake lines; adding a set of braided stainless steel lines will help with pedal feel (harder pedal, quicker initial bite), but they don't make you stop any better. That is a function of your pads, tires, and suspension. (and rotating mass and overall weight...)
