I'm baffled.
First Kline talks about the relation between suspension and tires and says things like, "Optimum spring rate is determined by the tire".
Ok, tire + wheel + suspension = handling.

Then he says for "purely aesthetic" reasons he went from the 17" OEM wheels to a square set of 19x8" M3 wheels. Say what? Hello??
So how much of the improvements were due to new wheels and tires as opposed to just the suspension tune? How can you say it's purely aesthetic? You can't tell us how well you engineered the suspension and then just say you threw on some M3 wheels for the looks.
