Yeah, I didn't like that. That is why cross-drilled rotors came about, but it's not why slotted rotors are still used. Anyway, the part about slotted street rotors being weaker is true, and that's what I was pointing at.
I see no problem with upgrading brakes. It's just that it's not worth it for a street car. The argument that adding power means you need to add breaking is flawed. You should not go any faster on the street just because you have more power. A Zetec automatic will go too fast for the street.
If you do insist on spending the money on bakes just because you want to, then do whatever you want. If you're not actually going to use them, it doesn't matter if you buy crap. If you really want to be able to stop fade-free with good modulation and torque in all safe street conditions, then stock brakes are sufficient and much cheaper than the bling ones.
Once more: You can do whatever you want to your car. But saying "I personally think brakes should be upgraded no matter what." is assinine. A car will not stop shorter with slotted rotors, and won't see any real difference from bigger rotors. So telling everyone that they need to "upgrade" is simply inane. This person said he needed new brakes and wanted to know what was good. Without specifically stating he wanted something to look fancy, the assumption is that he wants something that will stop his car. That's what stock brakes do: they stop the car, and do it well.
