NASCAR addresses foam issue by ordering changes source: nascar.com / David Caraviello Tweaks will allow for more airflow in right side of COT NASCAR will issue a technical bulletin prior to the next Car of Tomorrow race advising Nextel Cup teams to reconfigure the area around the protective foam on the right side of the vehicle, where some drivers have reported apparent smoldering or melting during the past two weeks. Officials believe more airflow will solve the problem, which plagued several drivers in the COT's debut race at Bristol and burned a hole on the inside of Kevin Harvick's car this past Sunday at Martinsville. Engineers from NASCAR's Research & Development Center attended Tuesday's test session at Richmond International Raceway, where they walked teams through the changes. Those alterations entail moving up the protective foam to build more space between it and exhaust pipes, where some teams reported cracks in the March 24 race at Bristol. Teams were also instructed on how to install the backstop and support shelving designed to keep too much heat from getting into the area. A bulletin detailing the setup will be distributed prior to the next COT race, scheduled for April 21 at Phoenix International Raceway. The complete article here at Nascar.com
