The team at aFe Power set a 2015 Mustang lap time record at Laguna Seca a few weekends ago while testing its suspension upgrades.
The 2015 Mustang GT ran a record lap time of 1:43:9 around the venerable California raceway with the goal of pushing its upcoming aFe coilovers and sway bars to the test in a track environment. This time bested previous high-powered Mustangs including the 2010 Shelby GT500 and the 2008 Shelby GT500KR.
