Yesterday Jeff Gordon rolled into victory lane at Michigan International Speedway, and today, several NASCAR teams are back at the track in what could be an important day for the 2015 NASCAR Sprint Cup Series season.

Aero, engine and tire adjustments are on the docket for today’s test. NASCAR is examining reducing more downforce, and Goodyear is expected to bring a stickier tire, per

“We have a prime rules package and also will be doing a low downforce package, because some of the drivers have been very vocal,” said Gene Stefanyshyn, vice president Innovation and Racing Development for NASCAR, via

Those testing include Jamie McMurray, Kasey Kahne, Danica Patrick, Paul Menard, Brad Keselowski, Ricky Stenhouse Jr., Aric Almirola, Denny Hamlin and either Clint Bowyer or Brian Vickers.

Here’s a couple early morning updates from NBCSN NASCAR AMERICA insider Nate Ryan, who is at the test:

    Good ,less downforce ,does that equate to loss of traction?
    Sticky tires .Does that mean more tire wear during green flag runs
    which leads to worn tires and driver doesn’t want to pit and loose position and waits for a caution period.
    Which will be caused by both of these issues

    When LED parking and directional lights are put on Camry’s , Chevies and Fords will they be require on sprint cup cars?

    I heard something about the drivers being able to adjust the track bar and wedge from their seat like IndyCars can. Any truth to that? Sounds like a great idea.

    I’m not sure about that ramification but I think it will lead to fewer cars breaking free just because another driver screws up their air with a near miss. The way it is now the downforce is so intense that all it takes is a break in the airflow at the wrong time or in the wrong way and they lose that downforce, lose traction and spin out or go into the wall. All without actually having been touched by another car.

      Nothing will solve the problem until Nascar starts selling new rear ends(independent suspensions) !
      The technology is just not there for the speeds and aero forces.
      They can make just as much money on them.
