Toyo r888; not so impressive grip nor longevity, I have not looked in to price.
My car: 2004 S2000/honda
Front 215-225 x 45 x 17
Rear 245-255 x 40 x 17
Thanks again, jeff
Hi Jeff -
My wife and I have tracked our respective cars for almost two decades now, and have used tires that are multi-purpose (street/track), and dedicated-purpose (track only).
Just this year, we both tried the Toyo R-888's. Before this, we ran the T1-S which was then superseded with the T1-R. Then we diverged when I ran the RA-1's and she stayed on the T1-R's. I also have Hoosier R-compounds, and Pirelli slicks that I use for competition events, which I have used as benchmarks.
When we swtiched to the Toyo R-888's, they impressed us both. It's much more forgiving than purpose-built R-compounds yet don't give up much grip to them. There's more forewarning of impending total loss of grip, yet manageable to the ragged edge.
They are a bit noisy for street use, but if all you're doing is to drive to the track, turn some very fast laps, then drive home, it'll suit your purposes just fine. I don't find them any noisier than the RA-1's, for instance. But, comfort tires they are not.
Let me answer your questionnaire for you:
Outright performance [initial/new grip]:
stunning. The stiff sidewalls made me think I was on Hoosiers so I just drove them as if they were. Yet they were much more forgiving!
How temperamental [must be shaved or require lots of heat?]
Nope, use them full depth. Unless you're going to do a 5-lap qualifying sprint, these are great.
Consistency over dozens of heat cycles:
Can't say, only have a half dozen events on them so far (each event may be a one-day or two-day)
[i]Value [miles per dollar]: So far, it gets full marks.
Relative availability [outlets AND sizes]: AIM Tire: American International Motorsports
Particularly good/bad applications [heavy car or 4WD, etc]:
works well primarily for track use, wouldn't use it in the rain, though.
