Five Axis Wheels Stock Height Question
 

I am looking at buying the FR-S within the year and would like to make sure I get winter tires put on my stock wheels right away. I will also be buying a set of wheels to use in the spring/summer. I was thinking the Five Axis SF:5 18x8.0 40 offset. Or if it would not look to over the top, I like the S7:F 19x8.5 45 offset wheels. I am not looking to alter the ride height or to have to change the camber for wheel rub. Any knowledge/opinions on this topic??

18x8 +40 would fit with no modifications. Just follow standard +1 sizing for your tires.

19x8.5 +45 would also fit, you would follow +2 for your tires.

Keep in mind that to keep the stock circumference, the more wheel you add, the less room for tire sidewall you have left over. Going with narrower profile tires will affect the ride of the tire negatively. Also generally speaking the larger diameter tire you buy, the more expensive they become.
