You can go back through the history.

1990 - Mark Martin is docked 46 points at Richmond International Raceway for a carburetor spacer that had been used before, NASCAR deemed that the carburetor was illegal. It cost car owner Jack Roush $40,000 in fines as well. Martin lost the title to Dale Earnhardt in 1990 by 26 points, had the points not been taken, he would have won by 20.
2002 - Mark Martin is docked 25 points at North Carolina Speedway in the 34th race of the season. Martin’s team is found to have a coil spring that is 4 3/8 coils, and the mininum for the spring at the time was 4 1/2 coils.
2007 - Carl Edwards and the No. 99 Office Depot Racing Team were docked 25 points for the car being too low at the quarterpanel, the crew felt it was damage from teammate Greg Biffle hitting them under the cool down lap. At the time Edwards went from being 2nd in the points, two points behind the leader, to being 28 back.

Now this past weekend the team is docked points for an oil-lid being off of the tank of the No. 99 Dish Network Ford Fusion. On Wednesday NASCAR announced that the penalty would be 100 driver & owner points, $100,000 fine had been issued to crew chief Bob Osborne and the team would lose the ten bonus points that would go with the victory if they were to make the Chase for the Championship. Edwards went from leading the points standings to being 79 points behind now leader Kyle Busch in the standings. And there is no telling how important that those ten points could be if Edwards does make the Chase.

While rules are rules, it seems that as of late, NASCAR has found a way to ruin Roush’s reign at the top of the series. Edwards won back to back races, and had they not done something, it might have given other fans and teams the idea that NASCAR had given Edwards the new golden boy title. However, they didn’t and as usual, the penalty is much harsh for Roush Fenway Racing.
