For Radical, he used a completely carbon fibre monocoque that can attach a Judd V8 or an AER Powertec Turbo to the bulkhead, but leaves it unstressed. Power is delivered to the rear wheels through Ricardo&#8217;s 750Nm sportscar box.<\/p>\n<p>Radical&#8217;s first customer, Rollcentre Racing from the UK helped design and produce the SR9 to replace their aging Dalara SP1 LMP900. Powered by a Judd V8, Rollcentre&#8217;s best achievement has been a fifth place at the Le Mans 24-Hour Race. Also present was Radical&#8217;s own AER-powered car which placed 15th. Sadly, both teams retired at the 2007 event.<\/p>\n<p>For the 2007 season, Radical made their debut in the American LeMans Series (ALMS) with them Van Der Steur Racing. This team suffered a racing incident during pre-season testing which delayed the debut of the car until the Lime Rock Park.<\/p>\n<h4>Story by Supercars.net<\/h4>\n<figure class='gallery-item'>\r\n
