I ran a test this morning with BoP on and the same tyre wear and fuel. I predict it's a no stopper.
Granted I tested with the BRZ but this is my tyres after 15 laps

Now, a pitstop for tyres only is 30 seconds so you have to be at least 2 seconds faster per lap. I think that will be hard with traffic.

I ran the BMW M6 after the 30 laps in the BRZ and was only .3 faster over a lap, even if I was much faster on the long straight.
So I believe in the handling cars over the power cars. 911, RS01, BRZ, and the MR's
