Glenn McMenamin is planning to defend his pro-am2 in the Porsche Carrera Cup GB this season after signing for a full campaign with Red Line Racing.The Milton Keynes driver only started racing at the end of the 2008 season and missed the opening Carrera Cup races of 2009 while upgrading his racing licence to National 'A' status. Despite that handicap, McMenamin went on to win the pro-am2 title after a superb season.Now, he says that retaining the pro-am2 title will be even tougher as the category is set for its strongest field to date. "It's going to be even more competitive than last year," said McMenamin. "There are seven or eight really strong drivers in the field and there will be some great racing. I'm really looking forward to another good year."McMenamin has switched to Red Line Racing where he joins Tim Harvey, Michael Meadows, Andrew Shelley and Archie Hamilton in a very strong five-car squad from the Cleveland team. "Red Line has got some great drivers and I can learn a lot from Tim Harvey; he's such a presence in the team."They have already had a couple of day's testing, including McMenamin's first visit to Thruxton. "That was quite an eye-opener," he said after his initial experience of the high-speed Hampshire track, which hosts the opening races of the season on 3/4 April.
