You planning to compete in stock class or STX for autocross? You need to stay with 7" wide wheel in stock class. 9" wheels would put you into STX and it will be very painful handicap wise if you don't fully prep your car with coilovers, camber plates, etc in that class. Very expensive to do it right.

I would suggest going with 235/40 Direzzas or Hankooks on 7" wheels. The difference in handling over stock tires will amaze you.

It's hard to make a car that excels at everything.

If classing isn't important, try a 245/40/17.

I would second using 245/40/17.
