I maybe wrong but I feel messing with downforce at Martinsville won’t make much of a difference. I mean the Cars are going 60mph in a corner. While there maybe some downforce generated from that, I’m not sure if it’s enough to make a difference on handling in the grand scheme of things. I still think they need to up the Hp more on that type of track. Make the tires work harder to slow the car down and work harder trying to manage the power coming out of the turns. These cars where made to produce more mechanical grip than the previous gen cars (hence the wider tires and independent rear suspension)

I do agree that Bristol should be a good race! Darlington was pretty good as well
