I Finally decided to try and put the 19's on my car. I thought it might be a world of new problems but, so far so good. Heres a couple pic's. Still havent put my hood back on yet though.
It depends on the offset. The biggest I'd go is 18 because I like to tuck while slammed and you can't do that with 19 unless you do a significant amount of body work. I've seen a couple people tuck 19.
One had bags and the other had coilovers dropped all the way down, but they couldn't be driven that way.
I will be in Champaign actually this coming weekend. I will take some new pics once I get my ww hood back on. I ordered new tails too. I think they came in today but I don't know if I will like them. And so Far I haven't had any issues with the wheels but wouldn't want to hit a hole.
