Tire Rack is showing the following tread widths:
MPSS - 9.6" F 11.2" R
R888R - 9.1" F 11.1" R
So slightly narrower, but with UTOQ of 100 compared to 300 for the MPSS, should be quite a bit stickier.

I just had full set of the R888R's in stock sizes mounted on a second set of OEM wheels for my Z51
Track only, Probably won't get to use them till June.
Ordered them from Simple tire for 15% discount and free shipping. Their execution was flawless in every way. Total came to $1214 with tax, delivered to my installer in 4 days
Manufacturing codes were 2617 to 4217

I ran R888R at COTA on the same deity wheel combo- 315F and 335R. With Stage 3 front and stage 2 rear aero, it was perfect. When I pushed too hard, all 4 tires went.
I will run them at my home track where I've run cup2 a few times and report the differences. My initial thought was they gripped way better than Cup2, but then I remembered they were 30mm wider a piece up front. I'm not sure if they'd grip better than cup2 if they were the same size.

Glad to measure them but unsure how best to measure the rounded shoulders.

Eesh simpletire is way more expensive for the cup2 on the grand sport...wow!!
Wish I could fit R888R on my stock grand sport/z07 wheels... dont want to shell out the money for new 18" wheels..
I can actually get about 4 track days out of the Cup2's

If I kept the factory MPSS up front and added a set of these to the rear (R888R) would the car be unstable ?

The grip level of the 2 types probably changes at a different rate with temperature.
Pure speculation here, but the PSS might have slightly better grip when cold, then after the tire temp comes up, the Toyos should have more. Possibly starting with oversteer changing to nasty understeer after a lap.

I wouldn't recommend it, but I don't think the car would be unstable... and I definitely wouldn't do it the other way around.

I'm going to run NT01.
They're kind of a stupid tire. Way too much tread. You're probably losing 20% of your contact path on the 888R.
