Darian Grubb: Ready For High Speed and Atlanta’s Ever Changing Track
_The track surface at Atlanta Motor Speedway has aged well. While most of the oil and grip is gone from the racing surface, the speed is still there. Drivers have to deal with some of the highest speeds on the circuit with some of the least grip. Darian Grubb knows that the amount of grip can change dramatically during the weekend, especially when the almost guaranteed rain storm moves through at some point._
_For this week’s Tech Talk Grubb touches on adjustability, inner liners and a brand new car. Making a car go around Atlanta well from the beginning to the end of the Labor Day race that goes from daytime into night, on a track surface that changes with the amount of rubber being laid down is a challenge. Grubb did it successfully when he was on the box for Tony Stewart and he hopes to do it again this weekend with Denny Hamlin._
