Date: December 26, 2007
Author: John Gutheil

Hairston Motorsports Racing is gearing up for the 2008 racing season and I thought some of you might be interested in an update on the new 2007 GTO racecar. Jim Hairston and his sons, Jake and Clint plan on racing the full Pacific Street Car Association (PSCA) schedule which opens at The Strip in Las Vegas January 25th through the 27th 2008. Again they will find themselves in the very competitive Pro Street division. Jake again will be the Crew Chief in 2008 and Clint “The Milkman” will be behind the wheel of the 2200 horsepower GTO. PerTronix is back on board as a major sponsor for the team. Here are the vital statistics for the GTO along with a couple of pictures taken recently.
