MY DSM and racing (all types). Please look!!

For brakes at the very least get some aggressive pads(with the 2 pots) with good rotors, SS lines, and some good fluid(Motul or similar). Otherwise go with a big brake kit as suggested earlier.

For suspension, make sure you do the rear sway bar(and probably not the front). On my car with: KYB AGX/Eibach Sportlines/ST rear sway/front strut bar/Ingalls camber kit front/Ingalls camber control arms rear, I can over or under steer on on/off ramps with my gas pedal.. very neutral.
