Hello. I have an 06 SS 2.4. I don't know which direction to take with the car. She has been stripped down and the doors have been welded shut. The rules at local race tracks have created obstacles for me. The tire rules say you can only run 60 or 70 series tires asphalt Circle Track. However, since I live in Virginia, I have an option of racing her at Virginia International Raceway road course. Last Sept. I replaced the transmission with a Pick-n-Pull special because my brother hurt the previous transmission after we added the cold air intake from AEM and a jet performance mass air flow sensor, and a no name header. Even with over 200,000 miles on her she still pulls hard. She is a salvaged car. Enjoy the pics.

 

What does 60 and 70 series tires mean?

 

Probably the sidewall.


OP, if you used FE1 brakes, you could easily run 14 or 15 inch wheels. Stock FE1 tire size is 195/60-15.
