Thinkin’ Out Loud: 2012 Pure Michigan 400 at Michigan

Jimmie Johnson had the dominant car once Mark Martin was speared by the pit wall opening in a scary, mid-race crash. But as J.J. was strolling to what would have been his series-leading fourth victory, a valve spring failed with less than 15 miles left to run. That handed Greg Biffle Christmas in August, gift-wrapping him a second victory after a green-white-checkered finish and a pesky push from Michigan native Brad Keselowski.

Tony Gibson: Rolling the Center on the Cup Circuit’s Flat Tracks

_The Cup Series heads to Loudon, New Hampshire for the first time this season this coming weekend. Last year the Stewart-Haas Racing team owned the track, with Ryan Newman winning the pole position for both races along with winning one of the two while his boss and teammate, Tony Stewart, took the trophy in the other. Newman’s crew chief Tony Gibson is our guest for this week’s edition of Tech Talk and talks about the importance of aerodynamics, mechanical grip and rolling the center of the corners._

Tech Talk: Inside A NASCAR Chassis Builder’s Setup

Mike Neff, Frontstretch.com: *Let’s start out with the differences in chassis. Late Models are predominantly in the Southeast where Super Late Models are more common throughout the rest of the country. What is the difference between a Late Model chassis and a Super Late Model Chassis?*

Greg Marlowe: A Late Model stock chassis is based more off a [Nationwide] car. Perimeter-style chassis with a steering box. They are based more on a conventional car style and they have to weigh 3,100 pounds. A Super Late Model is basically a 2,800 pound, straight rail, lightweight chassis, aluminum interior, just a quicker race car, period. There are less rules so we can do more what we need to do to make the cars faster and it just makes for a really good race.
