Street tires in IT??

[Xian]

Having raced Miatas for 13+ years, I believe the Toyo RA1 was the best tire.
All the things being talked about can be had in that tire

Having driven and raced on RA-1's, I'll disagree. RA-1's will chunk at full tread*. Additionally, they get quite a bit faster when shaved due to reduced void area. These two things combined results in a *big* advantage to those will to shave and toss tires and even *requires* folks to shave them for dry use.

*Possibly specific to FWD'ers.
