Tonight, we went and weighed in the car.
We got there right at 6 so we could weigh it in and have time to tweak it if necessary.
I ended up helping unload the track and getting it set up. Once that was set up, we checked in the car. Luckily, we only had to add a couple of BB's to make it hit the 5oz mark (and we didn't have to remove any... yea!)
We'll see how the race goes tomorrow.
