The fist and fost share at least one fairly profound aftermarket component need, a true limited slip differential. If either of these cars is driven aggressively for more than ten minutes, the brakes get very hot just from torque vectoring feature alone. As a street car both are great as is. But, there is room for improvement. As far as some people never being "done" with modifying their car, I would have to wonder if they ever had any defined plan or goal to start with! I can't wrap my head around the notion of never being done with something. I would also have little interest in buying "that guys" jacked up, half baked, half primered P.O.S.
