20's are to big and you won't have enough side wall to protect from bending them. Any wheel can bend or crack no matter who makes it.

Leave to 20's to "Pimp My Ride" and West Coast Customs.

19/20
I have 20 x 10's and 19 x 9's. I drive my car like it is on fire! I don't have a problem with handling...If this forum is so fair and against street racing or driving fast on the street then why so many posts about 20's and no traction? If you're driving around a curve or changing lanes etc. and your car is breaking loose, you my friend are breaking the law. I disagree with the loss in rwhp, it also depends on the weight of the wheel. You could put a heavy 18" wheel on and lose hp. I have a extra set of 19" with drag radials for the track. That way when I'm not posing I can get some traction! 
The words BLING and POSING should be banned from the forum they are to over done. BLING makes me 
when I hear it....Oh and wheels with SPINNERS Anyway 19" if you are worried about traction.

I know someone that lives in Las Vegas and did a two day driver school at the old Bragg-Smith school (now Spring Mountain Motorsports Ranch). He used the drivers school cars, which were stock Z06's for the school. On the last day, he drove his car on the track, which was a relatively stock Z06, except for the 18"/19" HRE wheel package. He was shocked at how much better the car with the stock wheel/tire package performed on the track compared to his car. As soon as he was done with the school, he sold his wheels and tires and went back to the stock ones.

Another thing to consider if you end up going with a 19"/20" combo is that you really need to slam your car to make it look right. The lower profile tires really exaggerate any fender well gap. Slamming the car looks great, but doesn't do the best things for the handling of this car. There's quite a few T1 racers that tell me that Z06 handles best at the stock ride height.

Lots of new cars come with 19 or 20's as standard.
We're talking 'on the street' here, no one drives, or should be driving like they are at the track, on the street!

I went 18/19 combo because my brother has 19/20 on his car and the performance suffers some, my setup its as good or better than stock.
That being said, I say if thats what you want you should get it.. Its your car and your the only one that has to be happy with it.
