I bought my car with 19's already on them. Never again. Stock suspension was OK. But after switching to KW V3's, I lost a month of good driving that I will never get back. It was rubbing both front and back. Ride was terrible. Performance don't even get me started. Life just wasn't the same. Immediately switched to 18's APEX ARC-8's and oh man did that make up for the month of terrible driving.
It depends on what you're looking to get out of your car.
19's: Looks > Performance
<19's: Performance > Looks
I'm selling those 19's if you're interested
