Looks good except for the brakes part. I run my drag brakes on the street and had them when I ran this class before so why the change now ? It would be pretty funny to get bumped to Mod for brakes.

Looking it over now jeff. Just a question on my behalf, what constitutes a "race brake" and what would it's advantage be over a standard braking system?

Race brakes are extremely light less rotating mass. I chose to lose weight by buying lightweight parts rather than cutting up the car.

The class is also called extreme street. Nothing wrong with a little friendly debate

To my knowledge there's not criteria for brakes as far as DOT is concerned like there is with tires. Street brakes have vented rotors where drag brakes generally are a solid rotor. Because of this they're easy to warp and aren't recommended for street use by the manufacturer.
