So I recently had a custom pre runner bumper built for my truck (05 silverado 1500 z71). I can't post a picture right now, but it opens up a lot of space directly in front of my front tires. Now I know I can fit 35's with stock 17" wheels if I crank the keys all the way, but will I be able to fit them with 17" aftermarket wheels that have a -12 offset? If you need a visual of my bumper, Google project stormrunner. Yes my fenders are still the stock ones too, compared to the flared ones he has. I will try to get a picture up when I can. Thanks!
