I am considering buying Z06 replica rims. I was going to go with the factory size 17 front and 18 rear but am now am considering going with 18 and 19 set up. Are there any pros or cons? My top priority is performance but the bigger rims probably look better. I also wonder does any one have pictures of a car with 18's on the front and 17,s with ET streets on the rear. Thanks for the help,Buzz
