So I rcently upgraded to 18" fuel wheels with 35x1250x18 Ridge Grapplers. They have a negative offset to give the truck a pretty mean look. I had pretty much settled on the Alcon brake kit for front and rear but when getting ready to order, I ran across a little note at the bottom I hadn't noticed before. Wheel Fitment: this brake kit will fit factory wheels and wheels with similar spoke designs and backspacing. The calipers will not clear wheels with low or extreme negative offsets. Please download and use Alcon's Clearance Guide to ensure your wheels will work with Alcon's brake kit. Now I haven't had the opportunity to download the Clearance Guide since I'm working overseas and don't have immediate access to the truck but this raises some interesting questions. Most importantly, what braking kits are available for negative offset wheels? This can't be limited to the Alcon kit right? BTW, if no one here has used wheelfire for their truck wheel/tire combos, you should check them out. Pretty fair pricing and they come mounted and balanced.
