Could someone tell me if this setup is o.k for the sedan?

Fronts: (114.3 bolt pattern)
18"x8.5 on 245/40/18, offset +35

Rears: (114.3 bolt pattern)
18"x9.5 on 275/40/18, offset +35

Thanks.

 

some will say it will and some will disagree. the fronts will fit. the rears will fit with either some negative camber or a little fender rolling. the rears could also fit closely depending on what size tire you use. if you are looking for a fit in the rear that is no worrys than i would not go with them. i have run that size in the rear, but i was running lots of negative camber and i was on streched tires.

 

not sure about rear wheels, but front wheel offsets are wrong. you need +40. see my painful thread:

read through it - there is good info there.

 

in 18 they probably will fit with some camber . . .

max. offset for front is usually +38, and rear +42

they're close enough that a machine shop could probably mill them to the above stated specifications without sacrificing the integrity of the wheel. just be sure the spoke isn't going to hit the caliper when you're done.
