William Byron's Thoughts: "I think the first practice went really well and that carried over into final practice. We made some new changes during final practice to get a little bit better and I feel like we were able to run some different lines on the track. Hopefully we can carry that over into the race tomorrow in our Axalta Chevrolet and finish out the regular season strong."
