Installing ZR1 wing on a C7Z

The 140 extra weight won't really be an issue would it?
As I would guess the weight distribution would be similarly bias front-to-rear as the current car.
However more front splitter or canards / winglets might be needed if the rear gets an extra 500lbs.
Thought?

worth considering but i can say i’d love more rear downforce. I’m running stage 3 up front and stage 2 out back. The rear end is always excited to rotate on me particularly entering a corner. Understeer is never a problem. I’ve been considering moving up to stage 3 in the back for this reason.

This seems potentially fraught with folly. The reason I say that is: aero balance. If that wing does, indeed produce the epic amounts of downforce we expect it to, the front end of the ZR1 (including its extra 140lbs) will be just as important: balance at speed. Otherwise you're probably going to run into a very light steering wheel and that oh-so-unsettling push on track.
Approach this one with care. Don't approach it like the aftermarket, as they generally don't have the aero knowledge nor testing facilities to verify and validate.

Weapons X sells the APR GTC-500 wing. This wing mounts to the deck lid of the car.
I would never mount a wing to a body panel, especially a composite panel like on the C7. Too much force and subsequent deflection.
Proper wings are mounted to the frame or other structural member of a vehicle. APR will disagree with me but how many real race/track cars do you see with a wing bolted to the rear deck/trunk. I see a lot of boy racer/ricer cars with this arrangement but no others.
I personally feel the APR wing is fine for cruisers/waxers/car show guys but not for high speed track usage.
Also, the ZR-1 wing was engineered and wind tunnel tested specifically for the C7. The APR is a generic wing and not specifically designed for our cars.

Maybe the hatch is designed for a wing. I have seen so much flexes on a hatch mounted wing that it pops the rear glass.
Beside, the c7 hatch is carbon fiber and it is only directionally strong. Just the stress crack on the carbon weave around the mounting points to the base alone is enough to scare me away.

That may be true, but my guess is Dodge developed the decklid so that it can withstand the pressure and downforce produced by the large wing. The hatch on the Z06 isn't built to hold up to that (and that's not a guess, in the leaked article of the car it is mentioned by Tadge that the hatch would crack if the wing was mounted on it and experienced high downforce).

The article says specifically an additional 140 lbs over the nose. Its 500 lbs of DF total, the question is how much does the Z06 already make with the stage 3 and what is the delta? The ZR1 splitter isn't that much more aggressive than the stage 3 and we don't know whether the additional openings create more lift or df.
Also that 500 lbs is at 200 mph. Other than Daytona you won't see much over 160mph in a Z06.

The C&D article states everything aft of A pillars is the same on the ZR-1 and Z06 except for the wing and wheels.
It will be interesting to see if it will be easy to fit the wing on a C7Z. I'm thinking maybe just a ZR-1 bumper cover with "slots" for the wing mounts and the wing itself and associated hardware might be all that is needed.
PLEASE, I realize many don't care for the wing for cosmetic reasons. I'm interested in performance improvement(s) on track. I don't give a damn how it "looks". I'm hoping this thread can address the topic of installing to benefit the guys who use their cars on track and not digress into a discussion about cosmetics...

P.S. FYI, Target and Wal-Mart are having a closeout sale this weekend on lawn chairs. Good deals to be had on the chairs you've worn out sitting next to your car at car shows/cruise-ins talking to your buddies about how fast your car is...
I don't care who you are, that's some funny **** right there!

Ultimately it will likely still turn faster laps than any of the other Vettes. It's just a bummer that we're now looking at a 3,700 lb 'track car'.
GM apparently tried to offset the nose weight penalty by putting more tire up front on the ZR1. Just as the Grand Sport is touted as being a better track car than the Z06 given the absence of the supercharger weight penalty, the ZR1 will suffer that penalty even more-so.
Ultimately it will likely turn faster laps than any other Corvette. It's just a bummer it's a 3,700# track car. The new manual transmission GT3 weighs 3,100. Imagine that baby with an LT5.
