Andy, I just realized we've had a few convos on FB and PM's. I'm pretty sure you'll be happy with a 19/18x8.5 +45, 18x9.5 +45. If you're not happy with the setup, you're welcome to add 3mm or 5mm spacers. Any lower than that, you'll need to do fender work.
If you purchase wheels that were too aggressive, you'll have no choice but to mangle your fenders to get them to fit. Going with a standard setup and adding spacers is the more logical choice in my personal opinion.
