If you want a diffuser to really work, you need to have it as part of a complete undertray that channels air from front to back with the diffuser section being the final part of the sequence.
Bolting on some plastic vanes to the back of your car is no better than a bandaid on a machete chop, and if someone doesn't care about the physics, then it's all about the rice...
Just saying.

There have been several threads about this I think you can find in the Tech or General section.
Basically, the contour of the rear hatch on the Coupe is better at minimizing the turbulence as the air is washing off the back of the car. The FRC is at a disadvantage in comparison if you're talking about high triple digit speeds.

Actually the aerodynamics of the rear window has almost nothing to do with the C5Z's top speed vs the coupe. The C5Z is limited by 5th gear @ 172mph.

It is gearing that is what causes the difference in top speed. Top speed in a Z06 is 171 MPH vs 175 MPH in a coupe. There might be a slight aerodynamic advantage to the coupe, but I can't really comment on it.

the Z06s hp and less wt give it the advantage.
Put the same hp, and reduce the coupes wt, well then we have a comparison

I guess if we believe you, we might as well go for world speed records in a SUV or pick-up truck, since aerodynamics don't matter.

aero does matter quite a bit.
and the Z is not slow, it is faster. But then again, I ( we) only get to the mid 150s on most race tracks long straights.
Aero matters so much that putting duct tape over the fog light / zo6 screens sees 3-4 mph more at redline 4th gear. Which means taking out a very popular CAI.

Wait a second. This makes ZERO sense. Gears and speed are linear. Making the car more slippery makes zero difference. If you are at 6,500 RPMs (same gears) then you will be going a set speed, aero makes zero difference unless you are power limited. Aero will help you hit redline more quickly, but it has nothing to do with speeds you are hitting in 3rd or 4th gears at redline.

Totally agree. I used to race and modify race cars for a living. I've driven a car that can literally drive upside down at 150 MPH due to awesome aerodynamic design.

There's a reason why General Motors use or fastback over the FRC body for the C5Rs, the aerodynamics were better.
And you can get better speed through aerodynamics because there's less wheel slip with less drag at top speed. A Z can have up to 5% difference in wheel speed and true speed when running at max depending on the road/track surface.
