WOW, coming from Indiana just to race with us!!!!
Ok, for tires use/run Sorex 36r's with either yokomo inserts, or green HPI inserts. Or if you intend to just run the tires for the night, then for massive grip try Sorex 32r's with yokomo inserts.
There is almost no interest in 19t here at SoCal, but maybe if some of the San Diego guys will come up then there might be a class for you to run 19t...
If any other help is desired, just ask....
