I want to find a way to cram 14 inches of gooey rubber under a narrow body. I mean, people already put 11's under there. What is 3 more little inches? (almost all of which would, I assume, need to come from the inside edge.) I wonder if one can move the factory floorpan tubs a bit, add some fluid-looking extensions, and then go for it, or if there are suspension things one may intersect.
