I can't judge the Z07 wing as I haven't seen it in person, however now seeing the Z06 in person I feel that the low spoiler is a better fit for the body lines of the car. The Z07 wing reminds me of the Karate Kid when he did that swan kick lol. You are right the Cup 2R tires will never get to temp on the streets and they will wear out fast. I have a 2021 GT500 CFTP which has the CF wheels and every time I drive the car I am worried about damaging a wheel on the slightest bump, they look nice with the exposed weave but very stressful to drive on. I think that it will be a tough time to even get the CF Ground Effects from the factory, an aftermarket solution will be needed. IMO the CC brakes are a must have as the base rotors look too small inside the wheel and brake dust will be a nightmare to constantly clean. Unless you are a pro driver on a track you don't need the dive planes, underbody aero strakes, Cup 2R tires, big wing or the FE7 suspension, it would be cool to have but not a deal breaker.
