i found some wheels i liked at quadratec. the choice is between 3 styles. d windows, soft 8 or the v5. they are the cragar steel ones. yes i know that there are probably better wheels out there but these fit my budget for now... im leaning more towards the v5 because i dont really see too many of them around. mostly soft 8 and d wins. my main question is what back spacing do i need. i have a 4.5 rc lift and it recommends 3.75 b.s. but i have seen other 4.5 inch lift kits that recommend 4 inch or 4.5 inch back spacing. i have 32 bfg km1 on my stock wheels and they rub on the coil, the sway bar link, and the lower control arm. just want to make sure i order the right stuff so i dont have to go through any problems. i know this is beating a dead horse but i used the search button and didnt find my answer. i dont know anything about wheels offsets or b.s. and how it all works. all i know is i want a 15 inch rim with 5 on 4.5. one thing i wonder about is why would different companies recommend different b.s. for the same size lift? the 32s are brand new so when i eat them up im probably going to 33 for sure maybe 35 so i want a wheel that will accept this. i would really like some education about wheels and their specs and measurments. ive looked up wheel measurements tables but i was really able to figure it out so any help is appreciated. thanks guys.
