Brad Keselowski is pretty angry with NASCAR these days.

After another top-10 finish in Texas, the defending Sprint Cup champion says what he's seen lately has him questioning everything he believes in. He's not happy about it.

Before Saturday night's race, NASCAR confiscated the original rear-end housing from Keselowski's No. 2 Ford and the No. 22 of Joey Logano, his Penske Racing teammate. That could lead to penalties, including possibly suspensions, the loss of championship points and/or fines.

Both Keselowski and Logano recovered to finish in the top 10 at Texas.

A week earlier at Martinsville, Keselowski got a penalty for pitting outside his stall, a ruling he still disputes.

Kyle Busch won the Cup race for a weekend sweep at Texas.
