| 2008 - Hobby Stock Rules |
| Lovelock Speedway will be using Rattlesnake Raceway Hobby Stock rules with some minor changes for the 2008 & 2009 seasons. Lovelock Speedway is looking into sanctioning IMCA Hobby Stocks in 2010. Keep this in mind while planning your next build so you will be legal. |
