It's not my car, HOWEVER, if I were to invest in a ZR1, I would really, really lean heavily to the big wing as the ZR1 is the pinnacle of Corvette performance, so you should get what makes the ZR1 ,the ZR1. The worry, as Rruuff states, is if you use the back storage a lot, it may get tiresome loading the car from the side (but I'm sure I would get used to it), and it's not like the wing will help performance on the street so, it would be like buying the car more for what it is capable of doing as opposed to buying it for what you'll be using it for. I don't know, I like the large wing as it just calmly lets all other performance cars on the road know that this is the king and just seeing the wing on the car in the garage would put one heck of a smile on my face knowing what I have.
