As a perennial back marker in this class, I was fine with our test run at 12 volts. I am not a dedicated tinkerer with gearing, but a simple crown gear swap is ok. The 13 volt setting would probably overwhelm my reflexes to stay happy driving my car. Re-gearing and adding weight at 13 v would just put me farther behind and make me a moving boulder in the stream. Thanks for thinking about our class that runs every year. Are there 2021/2022 cars being sold that are a vast improvement in some way that I could benefit from a new car, even if it means dropping the BFG livery?
