ROAR rules news: saddle packs and SCT tires

Saddle Packs:
The 2008 ROAR rules originally permitted saddle pack batteries with a maximum height of 32mm based on the batteries available at the time. The rule was change in late 2009 to a maximum of 25.1mm to make them consistent with the majority of battery packs available on the market. The batteries in excess of 25.1mm were grandfathered for a period of one year to allow drivers to use packs already purchased under the original rule. The one year period expired in late 2010, so batteries legal for ROAR competition for the 2011 season and beyond will need to be in compliance with the existing rule. The battery packs in question will be removed from the approved list.

Short Course:
The recent release of “wide” short course tires has prompted a review of the rule, specifically regarding width. The previous year’s rulebook didn’t include a maximum width, which in reference to rule 7.3.7 means that the tread width of the tire couldn’t exceed the maximum width of the wheel – in this case it’s 1.65 in. (41.9mm). Upon publication of the latest revision of the 2010 rulebook at the very end of 2010, a maximum width of 47mm similar to the provisional rules of 2008 was inserted, which was done without the review or approval of the Executive Committee. The width rule is therefore under review by the ExCom, the result of which will clarify the maximum allowable width of tire legal for use in ROAR competition for the 2011 season.
