OK so I decided to not wait and go with all F-70-15’s front and rear. The G’s won’t be out until maybe August, or later. So all 4 are mounted and balanced/on the car. Took it out for a quick test drive. They perform just like any other radial as far as I could tell from a quick spin. I’m happy with them. Been dealing with a back ache, so when I can, I’ll do a longer test drive, but so far so good.
