Where in the SCCA Solo 1 rules does the 200 tread wear limitation requirement drop off; anything above /Street, or above /SP, or STH, etc.??
If these were going to be my purely open track, or upper autocross class donuts/wheels (which they would have to be since this size wheel is a NO GO for H/Street
![Wink [wink] [wink]](/images/smilies/wink.gif)
), I would go with something like the Nankang AR-1s, (or even their CR-1, which is an A052 doppelganger/ripoff, at least as far as the tread pattern is concerned, if I had to stay with a 200 tread wear), but yeah, those would be a no go for street use.
