Depends on the class you want to run in. In H Stock, upgraded pads (EBC Green, Hawk Blue, Porterfield R4S) and a complete flush of the brake fluid and upgrading to a better brake fluid (Red Line, Wilwood, Valvoline Synthetic) is all that is really allowed. Of course, inspection of all brake hoses, calipers, etc is in order. In F Street Prepared, you can use the 11" Accord Wagon/V6 Accord front brake setup, requiring changing rotors, calipers (and mounts,) and pads. Using the two piston Legend caliper on an Accord is illeagal in Street Prepared, and pad selection is much more limited as well. In Street Prepared, however, you can use whatever master cylinder you want, so if you come across a heavier duty one that fits, let me know, as I am looking to upgrade my master cylinder currently. Stainless hoses are an effective upgrade. If your car is primarily a driver car, I'd skip the cross-drilled rotors, and use stock units. If you are looking into Street Modified, or Prepared catagories, then your options open up a lot, but the cost goes up at a much higher rate than the performance increase. The 11" brake upgrade is also good as you can use 15" wheels to race on and still have plenty of clearance, most other brake upgrades require at least 16" and oftentimes 17" wheels.
