Associated driver Ryan Cavalieri piloted his Factory Team B4, T4 and JConcepts BJ4 to the TQ position and win in 2WD Modified, Truck Modified and 4WD Modified at the 4th Annual Southwest Indoor Grand Prix (SIGP). This event was held at the top-notch facility, Competition Hobbies, located in Tucson, AZ. The unique surface at Competition Hobbies allows for maximum traction with 100% bald tires and extremely stiff foam inserts.

The SIGP also has a unique Pro 2WD class that pits the top drivers at the event in a head's up race where 5 of 6 rounds count towards the cash purse. Cavalieri took home the victory in this class as well. Rounding out the top three were Associated Team Manager, Brent Thielke and Associated/Reedy driver Ryan Maifield. Both Thielke and Maifield utilized the soon to be released LRP Sphere Competition 2007 and LRP Vector X-11 motors to power their vehicles.
