Now that I have finished my first pro race. I was reading the rules for ss again. It says not to exceed 5 ounces or 143 grams. 143 grams is more that 5 ounces. 5.05 to be exact. My car for April was 141 grams or 4.95 ounces. Am I missing out???
5 ounces is the limit on a scale that reads to the 1/10 ounce. So basically 5.045 (about 143 grams) passes and 5.050 rounds up to 5.1 and does not. I don't think you are really missing out, but if you make your cars weigh about 5.030 you will be fine.
