I did a test & tune day at COTA earlier than competing the next day and Sunday in the SCCA Substantial Tour races.
The observe ground is astonishing. The entire bumps possess been eliminated and the transitions between the former ground and the novel is terribly mild and rarely noticeable.
The exact criticism I heard turned into from some of the drivers in the prototype autos with very excessive downforce. They acknowledged they could presumably feel a varied grip degree between the former and novel when the ground received hotter in the afternoon.
Having raced at COTA as a minimal once per year since 2014 I had watched the bumps form over time and turned into very chuffed to seem for the outcomes of the resurfacing.
Awaiting WEC, IndyCar and F1 later this season.
