If you have glowing red discs on a big brake kit, then the stock brake setup would have been long gone! If you get the big brakes red hot, then you needed them in the first place to be driving at all.

Letting brakes cool is a solution, but kinetic energy goes up at the square of speed. As you increase speeds that is a lot of added heat. Performance pads can handle up to 750 degrees for a short time. Anything over that and they turn to gas. At around 700 degrees they wear like crazy! You will be changing pads and discs as often as every day. Normal brake fluid will also boil quickly at those temps (in reality more like half those temps). Meaning one or 2 hot laps and back to the pits. Upping temp ranges is a limited solution for near stock power. For longevity and reliability you need to get temps down. For lower temps you need more thermal mass and bigger heat sinks -> big discs

At 350hp 260mm big brakes are a joke in stock disc sizes. You need the AP racing 30-40mm thick ones to stand any chance.

If you had experience with big hp and fast driving you would know this..however tries it will find out very fast.

This all probably has no relevance to the OP, who will probably do street at typical blacktop or so powerlevels and the occasional track day (which will feel very fast to them). But that was not what triggered me. What triggered me is stock brakes being fine at high hp. They are not, they are dangerous. Just responding to that bit of misinformation.
