wheel fitment
 

i am debating if i should go 18x10.5 rear or 18x11 rear with either a 295 or a 305. fenders are rolled and i am prepared to pull them out a little bit if i have to. have a 06 350z with brembos. it does have a big single 2jz so im trying to get as much tire as i can(going with r888r) what do you think would work better the 10.5 or 11????

Well, obviously, if you're trying to get the most rubber underneath, the 11s with 305s. But, you make no mention of which wheels and most importantly, what offset? And, suspension, and whether you are willing to take out more camber.

I've run 295s (at stock height) on some 11" +30s but if you want it to fit a lowered car with the most aggressive fit, you will need to adjust the offset and alignment to suit your chassis.

IOW, not enough info.

sorry first time posting in here but i deff think im going to go 11" with the 305s, i used to run 295 on a 10.5 before the swap, im on bc coil overs and going with te37s. dont want to add camber to the rear.
