This is our last PWD. Our car is 5/8 thick and 2oz tungsten behind back wheels. And 1/2 oz in front I want to tune to a 4on the floor RR. Here’s my dilemma… my left back axel slot crumbled so I have to epoxy in the wheel which I planned to canter. If a thinner car will make a big difference I could start over but we’re already painted. We have 4 days till race day. Should I just concentrate on tunning? Really hope to win districts this year. We have won our pack the last 3 years. I usually do a 1/2” thick body design but have no idea why I went with 5/8 this year.
