Montoya was first in the morning test, when the track was at its coolest, while the afternoon session was lead by Paul Menard, followed by the same Montoya, Ryan Newman, Jamie McMurray and Jimmie Johnson.
The new spoiler was tested alongside what most expect to become the new aero package for most of the Sprint tracks. The package comprises the aforementioned spoiler, left-side deck lid and window fins, all designed to keep the cars on the tarmac, with all four wheels.
The new spoiler, however, was found to bring little changes in the way the cars feel and behave. At least from the drivers' standpoint who, for the second time, said there's no major shift in balance and handling.
"It was good to know and put out of my mind that the spoiler was going to be a drastic difference in the way the car drives," Kevin Harvick said according to Autosport. "That is not the case. The car has a lot of grip with the tyre combination and the spoiler, so it drives really good."
"We went right to work on the things that we needed to because we felt comfortable with the car. I think that's been good and everything has gone well so far."
Separately, NASCAR announced the aero and restrictor plate package for superspeedways. The spoilers are set at 4.5 inches high (without the higher side-extensions), 63 inches wide and will have a 70-degree angle at other tracks. For Talladega and Daytona, a smaller restrictor-plate, with holes measuring 30/32nds of an inch, will be used.
