Thank you to all drivers and race teams. CNS is proud to announce that the oval track show and 2012 registration was a huge success! This year, we had more racers register at the show than in the past 3 years! Colorado National Speedway staff and owners want to thank everyone for their positive input and support. Let’s all have a fun and safe 2012 race season.

Thanks, we couldn’t do it without all of you!

CNS Management

All 2010 GAM rules apply, except for the following changes:

1) 8” Hoosier slicks F75 right side and F53 left side.
2) 56% left side max weight.

We expect no other changes for the 2012 season, but stayed tuned to CNS tech news for further updates
