What a busy week last week.
Did some measuring and head scratching and realized that the rear quarter was pulled out slightly more on one side than the other causing my one wheel to poke more than the other. I pulled the fender a bit and now the rear fits great.
As for the misfire / hesitation @4K we tried everything. MAFS, Coils, Plugs, grounds, exhaust and everything in between. After 2 nights of scrambling, We then turned our attention to the fuel system and the culprit ended out being the inline -6an fuel filter.
Car runs great now.
Squad.
