does anyone kno if 20x9.5 +17 fronts 20x10.5 +13 rears would fit...on the 07+ sedans...

 

Not even close.

Fronts in a 9.5" would be tight...maybe around a +40-45 offset required.
Rears in a 10.5" have been done but only in a higher offset....around +48

only way i see it fitting is slamming the right, camber it out and some major fender pulling type of work

 

Not unless you are going to be the first wide body sedan!

 

what if i go 10.5 +40 with strecth tires

 

that i'd say would work (lowered and camber)

 

you can do a 10.5+40 without stretching the tires if you drop the car (over and inch) and run around -1.8 rear camber. You can still run a 275/30 tire with those specs.

If you dont want to run that much negative camber then you can get a 255/35 tire and run -1.4 or so camber as long as you're dropped (over an inch)
-GP-

 

Do the 04 and 07 sedans take similar offset and widths? ie do the both have similar guards and take the same maximum offsets?
