Don't believe there is an option to upgrade the brakes. There is brake bias controller settings under your cars setup. Depending on the car, you will usually want to take a few points out of the rear and add to the front. 8 front/ 3 rear seems to work well with me for most setups. Also, turn your abs up from 1 to 2 or 3 wherever you feel comfortable at without locking up the brakes. It will assist in braking response somewhat allowing you to brake a little later going into a turn. Hope that helps answer your question and fill in the gap on how to improve braking.
