I have a question about this wheel/tire size and fitment on my 2005 G35 coupe. It is important to mention that my car has the OEM sport suspension, and I am wondering if these specs will fit flush without rubbing or scrubbing, and without doing spacers/coilovers. I am also wondering if this tire size will mostly fill out the wheel well and look good even without being lowered.

Front: 19x9.5 +22 with a 255/35/19 tire
Rear: 19.10.5 +22 with a 275/35/19 tire

After researching this a lot, it seems like many people run this setup and it should fit flush, but I just wanted to collect some of my own information.
Are there any adjustments I should consider regarding this tire size and wheel width/wheel offset?

Also on a somewhat related note, does anyone have an opinion on the Kansei Tandem wheels as far as quality goes?
I would love some real wheels (at least Enkei's) but I am having a very difficult time finding any in these measurements.
