Seeking Wheel/Offset Guidance
Hey guys,
I'm going to be getting a new wheel/tire setup soon, and need some guidance. I've narrowed my choices down to the CCW Classic, BC Forged MLE81, and Forgestar M14, all of which have to be custom ordered. Planned sizing is 18x9.5 (275/35) front and 18x10.5 (305/35) rear. I've gone back and forth between +50 and +55 offset. I'm using this website for my calculations, so I hope it's accurate https://tiresize.com/wheel-offset-calculator/. I had almost settled on +55 since it shows the sidewalls would be .59" further out in the rear and .32" in the front. I can handle a little poke, but would like to keep the tires as flush with the top of the fender as possible. Today I was verifying that fitment with Forgestar, but they told me +55 won't work in the front because it won't clear the brake caliper and that I would need to add some camber for the 275/35s to work. Does that seem correct? Any guidance anyone can offer is appreciated.
