OK, thanks, Dan. I see where you're coming from...
What tires are you using? I used Nitto Drag radials on the Cobra occasionally and boy, do they kick up debris. I have Goodyear racing billboards on the GT40 and they are sticky but don't pick up as much; still more than the street tires. The Dynamat's working well so far. One corner started to peel off, and I just paid attention to PREPARATION (ultra cleaning) when I replaced it.
