Anyway the track record was lowered again this year. My daughters rainbow car (painted with brushed on Walmart acrylics and clear coated with Krylon spray 100% by her) set the track record early as the siblings raced first while we waited for a late Cub to arrive. She ran a 3.1109. Our rules are strict, 100% box stock wheels (no modifications other than bore prep), stock wheelbase and graphite. Her new track record stood all day until the last heat of the day (we ran 54 heats) which was when my sons car ran a best time of 3.1104 in his eighth and final heat of the grand finals. We have never had a car speed up as the race went on, so that was fun to see. My daughter actually ran the best cumulative 4 heat time of the day. My son had the best single heat and was fastest of the 14 cars in the "Grand Final". the second place car to him was second by only .003 second per heat in the average! Third place dropped off a bunch back to .047 seconds. It was really fun seeing the fastest two run neck and neck within .0005 seconds on one heat!

last year I forced a family to take lightened wheels off of their cars and replace them with stock wheels we had on hand. The wheels were sanded round on the corners, but upon further inspection by me no lighter than the lightest stock wheels that can be found. The father has not spoken to me since, and his wife is on the pack Committee (I am also a den leader). Tech is not for the faint of heart. This year the wheels were again sanded, but the letters were still visible (barely) and the tread bumps could be felt (barely) so I let those cars go not wanting a repeat of the wheel swap debacle. Coincidentally this was the family that pointed out the wheelbase issue this year and wanted it corrected.
