On Jan. 21 at the NASCAR Research & Development Center, officials from NASCAR are expected to announce a series of rules revisions, some drastic, others less so. It is expected that the controversial rear wing, one of the COT's most defining characteristics, will be scrapped in favor of a more traditional blade spoiler like the NASCAR Nationwide Series cars use. Also being looked it is the front splitter, which runs parallel to the racing surface and replaced the conventional front air dam. NASCAR officials also are talking about eliminating the no-passing zones at Daytona International Speedway and Talladega Superspeedway, as well as other as-year unspecified changes, all aimed at helping re-energize interest in the sport. NASCAR officials said Saturday at the Sprint Sound & Speed [in Nashville] event that final decisions about the modifications have not been made, but will be announced Jan. 21.(SPEEDtv)(1-10-2010)

AND: NASCAR teams are testing this week at Texas World Speedway [#12-Keselowski tested at TWS last week], to see how that planned new rear spoiler might work on their Sprint Cup cars, according to stock car crews. NASCAR officials are tentatively planning to change the rear wing on the Cup cars to a more standard flat rear spoiler, beginning either with the Bristol 500 March 21 or Martinsville 500 March 28. But it will be the Cup races at Phoenix April 10th and Texas April 18th that would be the major test of the new spoiler, which is designed to add downforce to the cars and make them handle better. There are more changes coming too, apparently, with Daytona cars possibly sporting a new 'shark fin' on the rear deck, to make them more stable when they get sideways. The 'shark fin' would be a three-inch tall fin running from the top of the rear window to the rear wing, according to crews. How that might be tested is unclear, since NASCAR has banned testing at Daytona and Talladega. While the long-standard flat rear spoiler on Cup and Nationwide cars has basically been just a $5 piece of steel, bolted on to the rear deck, the new flat rear spoiler will apparently be another 'over-engineered' piece by NASCAR, sold to the teams by NASCAR and installed at each track by NASCAR officials.(mikemulhern.net)(1-10-2010)
