The use of gym room weights on the front and back piqued the interest of many intrepid fans and most figured out their purpose – the plates are used as ballast to make up for the weight lost by removing the bodywork and wheels/tires to perform chassis setup.
Most teams perform their setups with only the driver’s weight accounted for (usually by placing sand bags or lead weights in the seat), but WTR prefers to account for the exact weight as-raced when making its tweaks and changes.

There’s a lot more to uncover and explain once the Roar arrives, so we’ll save our next installment for an in-depth look at all three cars. We’ve seen a lot of the Cadillacs, and there’s still more to show, but next time, there will be a heavy emphasis placed on the Mazda and Nissan.
