Encounter less aero resistance? Foxes are some of the most un-aerodynamic cars on the planet. Everything you have rattled off is solved with a head change or another pulley. You dont seem to understand what I'm saying, your speaking in relative terms. Your comparisons are so miniscule that you probably couldn't even find substantial evidence to back them up, the drag coefficients between a convertible and a coupe would not even be measurable in a quarter mile pass. Hooking better is solved by subframes, $30 at your local hardware store. This is what I mean by relative, the actual comparsion to say that coupes or hatches are better is a weak argument when you factor in just how little of differences there are in drag racing. Road racing is quite another situation.
I understand your arguments... I have subframes, I have pullies, I have AFR 165 heads... etc... Still, comparable hardtops are quicker, and hook better... And coefficient of drag can only be accurately measured on an immovable object. A rattling top, even an unnoticible movement can mean big aero disturbances. Rattling in the wind, making waves of air that either add constructive or destructive interference is GOING to cause larger resistance to air. I don't want to go into trying to prove that so I'll concede for sanity's sake...

8.8 @ 82.5 is the best the car's done in the 1/8th. That was on Nitto DRs with 16 psi of air in mid-day october (and with a 3.55 gear; the 4.10 has gotten close but no cigar). A hot track and cool air... Yes, I know lightly modified coupes that can do better. I've never gotten the car to hook well, from slipping the clutch, to dumping the clutch, to every air combination and burnout elapsed time you can imagine...
the facts have been explained, LS1 coupes are heavier than fox verts, so they are inferior, right?
Well, no... If you're referring to hard tops, they yield less chance for torsional flex along the drivetrain axis, and they're weight proportioning is better than a Fox...
Stock, my car's best was a 9.62 @ 76.5 MPH in the 1/8th with Nittos and a 3.55 gear.
