Mustang + GT = GTT!! SEMA is going to be insane this year, especially with this GTT! ZeroTo60 Designs created this mustang with 2017 GT inspired design! Totally new bodywork, splitters and wheels give it a GT-esq sexyness!! The 5.0L coyote V8 now has a Supercharger to make 800HP!! YES, it's hitting production in limited numbers starting in 2017!
