In this situation no matter what brackets you have a heat gun is your friend.
Yes. I ran Nitto NT01 315-30s out back on the stock 11s with (14mm I think) spacers and they still rubbed the liners in front of the intercooler pipes until I forced the original Turbo liner brackets back a half inch or so then heat-gunned the liners and forced them back too.
That was the easy part actually. I am jealous of Pwderhound's half-hour fender rolling as I suspect he used a proper fender-roller or at least a baseball bat. I did my four by hand with just a cushioned hammer and a heat gun over half a day or so. They came out great, but next time I'm going the roller or the bat route!
