once again.offset question for a G35 sedan
#3
absolutely will not even come close to working. if you want to run a 9" in the front you'll need atleast a +40 but it might come close to hitting the suspension if you dont use a stretched tire (235/35/19) and in the rear, you'll need a +45 and a fender roll. If you plan on running 9's up front you better have alot of negative camber.

For the front on a sedan, a 9" wide rim on 35mm to 38mm should be fine as long as you don't go taller then oem tire rolling diameter with a maximum width of 255. I have been running 18x8 on 35mm (courtesty of 10mm spacers in the front) with 255/40-18 In the picture below, notice the tire to suspension upright clearance.
looking up, the tire's outside edge camber's inward on compression and does not touch.
I did do a fitment test where I installed my rear tire setup onto the front, 265/40-18 same rim 35mm effective offset. Tire clearance to the suspension upright is about 5mm. However the tire does not clear the front fender lip. With shorter tire like 265/35-18 or 265/40-17 and a little more offset, 38mm
or maybe 40mm a 265 wide tire should clear.
In the rear, 9" or 9.5" with 45mm offset would be the best bet to allow up to 275 wide rears.

Yes but Chico also says my front combo will rub on the inside but it rubs on the outside.

We all have to remember that when we push the extream's on front tire width's that tire height becomes VERY important. To the extent that going shorter then oem rolling diameter, buy's you clearance from the suspension upright and the fender lip. Go taller then oem and it will have the opposite effect.
Thing I"m realizing, I may be able to pull off a 265mm front, but I may not be able to dial in more negitive front camber when I want to because I pull the tire inward as far as possilbe to clear the fender lip. Not sure 265 will be worth it if I can optimize camber.
I'm going to do another fitment test, this time I'll pull the coilover assembly off and disconnect the sway bar so I can get the tire and wheel as far as possible into the wheel well, then I'll turn the wheel side to side and see clearances for sure to the fender lip. Try as I might when I used a floor jack to try and push the wheel up into the fender I could not get it close. Spring stiffness and swaybar stiffness kept me from succeeding.
