Matt Kenseth says NASCAR's penalties against his team are "grossly unfair" and "borderline shameful."

Kenseth's team was hit with some of the harshest penalties NASCAR has handed out Wednesday after his race-winning engine at Kansas failed the post-race inspection. He says one of eight connecting rods on the engine was too light — by 2.7 grams.

Kenseth was docked 50 driver points in the standings — two more than he earned for the victory. But he says he's angrier about the penalties given to Gibbs and crew chief Jason Ratcliff. Both were suspended six weeks.

Gibbs also had his owner points frozen, and Ratcliff was fined $200,000.

The points penalty dropped Kenseth from eighth to 14th in the standings.
