Red Bull will be protesting over Brawn's 'illegal' diffuser

You may have read my previous post about other teams thinking about lodging a protest about Brawn GP's rear diffuser. Up until then, it was just talk but now Red Bull have came forward and will issue an official complaint about it if the 'illegal' diffuser passes the FIA scrutineering. Now it's not just Brawn GP who will be caught out by this as Toyota and Williams also use the same.
"It's illegal," Helmut Marko, a Red Bull adviser, said. "We'll make a protest [tomorrow] if the component isn't modified to conform to the regulations, because that diffuser guarantees a five-tenths [of a second] advantage per lap. Seven teams are certain it's illegal."
