Chris B. (Philadelphia, Pennsylvania, United States)
Definitely love it

This definitely a great fit from the look to the performance. Would recommend it for a clean look in the engine bay

Great product

Good quality for money

Only gripe is they are a little longer than i’d want but they work like a charm. No need for heat shields on your spark plugs wires.

Where is it?

I never got that order. My new address is 18 Tides Edge Place, Sacramento, CA 95835

Exactly as described

Exactly what i needed. I'm so glad these guys could explain the difference in the pad material compared to the 3 other places I called. Will be back soon.

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
