Default ISF vs RC 350 Tires, 265 R / 235 F....one more time

I see the new 2015/16 RC 350 has 265/35-19 R and 235/40-19 F

I read every thread here and most people say 265 rear causes handling issues w/ ISF
and that keeping diameter close to stock is key (26" in our case)
so...
any input, anyone run these sizes ?

I don't want to go lower profile, I want more sidewall for better ride and figured the 265/235 combo would be prefect

so, why won't these work well on ISF? (I have wider 2012 ISF rims)

and I see the RC-F is 275 / 255, so WTH?

Running those exact sizes and have had no issues... granted I haven't tracked it, but have noticed no ill effect in my spirited mountain drives.

If you have have the 2012 and up wheels with the 19x8.5 fronts and 19x.9.5 rears, running those tire sizes should not have any issues. That extra .5 really does help stiffen the sidewalls.
