If you are seeking something closer to the concept car look (which I was, too) the 20" wheels wont quite get the job done. 21's look good to me, but you have to hunt around for decent pricing due to the odd size. Last week, a guy next to us at a stoplight says "i have the exact same Camaro at home. Why doesnt mine look this good?!?". He thought wheels, too (and he has the 20"). All comes down to personal taste
