So I've got an ZO6 FRC: I've converted it to a Targa and removed the BSM's, but you know I don't really notice the difference in speed. Mine is scary fast, so a coupe would be ... ?
Also it's black - is red faster too?

No, Silver is the fastest.

My vert which is more closely shaped to the FRC/Z06 body than the coupe goes pretty good and I don't even have BSM's.

Actually, a more interesting question to me is:

Given that the coupe is the most aerodynamic car of the bunch, could it make a difference at the drag strip considering the speeds?

True because the Z's FRC top creates turbulant vorticies at high speeds resulting in severe form drag directly behind the rear window. The C5-ZO6 was designed as a track/AutoX car where high velocity takes a back seat to excellent handling and low end power.

I would say yes based on aerodynamics. Assuming you found two identical cars where the only difference was that 1 was an FRC and the other was a coupe, the coupe should win. Another question though is what's the weight difference between an FRC and a hatchback coupe.

Didn't think about that. I think if the cars are running very fast the coupe will win (talking 150mph+ runs). If they're closer to stock the weight difference would likely be more important.

Why don't you list the other real reason... gearing. The shorter gears of the Z ensure it gets to a specific mph quickly, but limits it's overall top speed. Given unlimited room, the car with the taller gears will eventually pull to it's higher top speed.

While it is true the c5 is more aerodynamic,I am not so sure that is the entire recipe for top speed calcs.The lower gearing of the Z will limit it's top speed as well

Also,IIRC,the weight difference between the z06 and c-5 is in the neighborhood of 80 lbs.I remember I was surprised that it was so little.Much is made of this difference,although it is there,it is not that much of an advantage to me

Not trying to **** anyone off,just an observation
