Im looking to purchase some winter rims since my current ones are damaged and I already have 19" Blizzak winter tires.

I'm wondering would 19x8.5 all around with +35 offset fit? Wondering if it can fit the rear okay. I currently have the G37 sport with the big brake kit.

 

The big brakes usually aren't a problem in back, the fronts can be tricky. Here's some F&R templates if you have the wheels on hand, or you can email it to the vendor to check for fitment.
