Hmm, I didn't know about all the thicker metal, because I only spotted the mentioned differences from a million pics of the coupe I have,

Maybe the thicker metal is the reason that my pinch welds held up so well compared to my friends S4 on which the floor caved in a little bit, lol. Thanks for the in depth comparion.
And yes, I used to think that the coupe is cooler, but the FC3C really IS the cooler car, especially with a turbo with good suspension.
I want to turbo swap mine, but being a senior in High School, and making min wage, it's kinda tough, haha.
