Toyo® Proxes R888R DOT Competition Tire
Scargod (New Haven, Connecticut, United States)
Noisy and not sticky enough when pushed

I have run quite a few Hoosier R7's but wanted the size available in the 888R's for my new BRZ. For one thing, I had forgotten how noisy they are! I could live with that if they performed better on a dry track.
When pushed hard for 20+ minutes they eventually build up enough heat to start getting greasy and losing grip.
For many they will be adequate for track days, but I drive my cars too close to the limit. A better tire for me in the dry has been the Eagle Supercar F1 3R's.

Haven't received them yet

As above

Not a fit

Unfortunately the belt did not fit, it was was too long, my fruend had a 2018 SRT, he had the same problem with his order.
The transaction process was easy, the belt seems like good quality, too bad it didn't fit
