Ops department. I was wrong about the spacer size on my rear wheel. As a result, my measurements were off and a 9.5″ wheel is not going to be wide enough.
Looks like I’m going to have to go with the Forgestar CF5 in brilliant silver; still 19 x 8.5 up front with a 245/40, but a 19 x 10 in the rear with 285/35 tires.
These wheels are rotary forged instead of cast, so they should be much nicer in the long run.
