I have a 2015 IS350 F-Sport and want to swap out the wheels.

Currently, the vehicle has the 18" wheels that came with it.

I purchased a set (all 4) of 18x9 with a 38 offset and have been looking at different sites to see if there is a consensus on tire size to use that is closest to stock size as to not mess with the speedometer.

My car is lowered on RS*R Super Down Springs so the fitment is something I want to make sure works.

Any advice would be very helpful! Thanks in advance!
