Great preview of the PSI M4 headed for SEMA.

Words by PSI:

While the SEMA Show was not the full end game we had in mind when our Sakhir Orange M4 arrived months ago, it was certainly the first major stop on a fantastic journey we had mapped out. From the beginning, we all knew the implications involved, and that our vision of an M4 “Club Sport” theme had to be unique yet purposeful.

GSR Autosport gives us the skinny on their Global Time Attack M4 prior to SEMA. The GSR Autosport Global Time Attack project car is being developed to run in the 2015 GTA Pro Am Series in Street Class. The overall concept is sort of a Jekyll & Hyde thing where certain parts will be able to be swapped back and forth – between track duty and street duty – parts such as the front splitter, rear decklid/wing, roll bar, seats, wheels/tires, etc.

GSR started … CONTINUED

Watch the BMW M4 GTS in action on the Nurburgring as it undergoes further testing.
