ok i am getting a 6 inch fabtech with front coilovers on my 06 4x2 f-150. I am wanting to crank up the coilovers 2 inches and put 36x13.50 r20 iroks, but the rims i am looking at are 20x8.5 and have a backspacing of 6.13 inches and have an offset of +35. The problem is that fabtech recommends a wheel with 5 inches of backspacing and i am wondering if these rims will work on this lift and these tires? Do i need to find new rims or do i go with a procomp lift with coilovers????

 

i would go with a wheel that will stay more flush with the fenders as close as possible, sounds like the wheel you got in mind will do just that. Iam going the same route as you. I actually have a 05 2wd with a 6" suspension and 3" body and i have been told that i will rub a little with some 36 or 37" tires, but what is hurting me is that the wheel i got is a 20x10 w/ 4.5"s of backspacing. i would go for it thats what iam doing, and if u rub, so be it.

 

Two things

1st - Don't put a 13.5" tire on a 8.5" rim because the tires gonna be very soft in the middle and wear down on you pretty fast. You should be at least a 10" wheel

2nd - Just go with what Fabtech says. Mine are a -12 offset and there's really not that much space between the tire and knuckle as is right now and that's on 18" wheel with 35" tires which are only 13" wide. You're gonna end up buying tires and getting screwed. Granted mine's 4x4 so don't know if that is gonna make a big difference but why not just listen to Fabtech?

 

because i want a huge tire and the tires aren't that expensive so... and if it doesn't rub then i don't care

 

1st - It's no different than guys putting 35x12.50s on stock wheels. Sure it won't wear as good as if it were on a wider wheel but it'll work. The correct air pressure and rotating every 3,000 miles or sooner and they will wear good enough for most people.

2nd - They will probally fit. I've seen plenty of people use other wheels and we're fine. Just like Fabtech only recommends a certain backspacing for their dual steering stabilizers, they worked fine with my Helo Maxx 6s and Rancho 4 inch. Regardless, I would still try to find a wheel with like 5-1/2" backspacing.
