Super Stock classification

[FireSale]

They should put all this info in one place. From the 2020 SS Weight section.

"WEIGHT


All cars will be permitted to run on the class minimum weight, but may be no heavier than the minimum for the next heavier class. Car can move up (lighter) one class or down (heavier) one class. If weight is added, must be properly attached; see BALLAST. In cases where NHRA has placed a performance rating on the engine, use the factored horsepower. Class and classification weight are determined without driver. Once classification weight is calculated, 170 pounds is added for driver to arrive at total weight. All cars are weighed with driver."


BALLAST: 100 LBS MAX.


Note that there are two weights here: Shipping weight from the guide and total (scale) weight at the track. Class is determined without driver. I don't know if class would change if you were at the max weight for a class and adding 170 would put the scale weight one class down.

The goal in adding and subtracting 100 lbs in SS is to let you place the car at a favorable weight. If you are at the bottom of a class, adding weight would let you run at the top of the next class down. A better place to be. When you get into GT and Modified the weight adjustment increases to 250 but you have to determine the shipping weight differently.


Someone should make up a worksheet on classing a Stock or SuperStock car and pin it here.
