curious to know if anyone here or elsewhere has ran a 20x12 set-up for the rear and what modifications did they have to do? what does anyone think of a 275/30 rear tire selection with this size wheel.

 

unless you have some decent performance mods, going to a 12" tire is going to slow you down considerably. it'll drain your torque.

 

I'm running a 295 on a 11" and it fits perfect.

 

wont happen. here is why i know:
i have that size with a 3" widebody kit on both sides. i have 2 inches i could have played with under the car. thats it. so if i do the math, here a goes:
20x14s. less 3" of the kit = 11" max
NOW, that said, if you were REALLY lucky and the inner wheel well is an inch more than the stock you might have a chance. but here is the issue. on 3 piece wheels they are made of (duh.) 3 pieces. the inner hoop. outer. and center. unfortunatly most wheel makers dont make the inner rings that extra inch. its stupid, i know. i ran into this issue. so here is my advice:

have wheels MADE. ask for a ring to be sent to you. then measure how much space BEHIND that ring you can go. so if you have stock 6" inners and you feel you can go 7", cool. you need 7" inners and 5" outers. thats the math. but you need to make sure. measure twice, cut once. i made the mistake of eyeing it up. DONT MAKE THAT SAME MISTAKE
later bro

 

thanks guyz

 

+1, that's good to know
