Rules Changes  For The 2008 URSS Season

 

December 9th - The United Rebel Sprint Series has announced several Rules changes and clarifications for the upcoming 2008 Season. These have been made to keep the Series affordable and to clear up a few gray areas in the rules as they have been the past two seasons.

Rule Changes for the 2008 Season include:

1 - World Products #042650 305 Cylinder Head will be optional for use in URSS Competition during the 2008 Season. The Head will become the Spec Cylinder Head for the Series in 2009. Cylinder heads will have to be purchased through the URSS and will have to bear the URSS Stamp to be LEGAL for use in Competition. Also, if you are using OEM Heads it is strongly recommended you have them inspected and stamped, any OEM head that is not stamped will be subject to removal at anytime by Race Officials.

2 - Raceceiver Radios will be mandatory for all URSS Sanctioned races. No Two-Way radios will be allowed. This will allow URSS Officials to speed up the line-up process during Cautions to expedite the shows.

3 - Arm Restraints will be required, with Head and Neck Restraint Systems are Strongly Recommended.

Clarifications to the existing Rules include:

1 - Compression Ratio will be 10.50:1 Maximum and will be checked this Season using the Whistler Compression Ration Tester. 

2 - Maximum Rocker Arm Ratio will be 1.6 to 1. 

3 - No Knife-Edging or Drilling, Undercutting or Lightening of the Counterweights on the Crankshaft will be allowed.

4 - The Hoosier “105/18-15 Hard” Right Rear will be required at all URSS Sanctioned Events. No Tire Softeners may be used and the tire must Durometer at least 50 before and after a race.
