Welcome BX1,
As Thudmaster said, NorCal Cobras meets at least once a month for breakfast and a drive, usually on the third Saturday. The meeting place varies so watch for postings.
I run Indy 500s on my SPF. I like them. They are sticky and give good mileage. I'm at 15,000 miles with plenty of tread left.
Give us some details on your SPF. We love to hear that kind of stuff.
... And post some pics as well. We never get enough of that either.
See you at the next gathering.
