Autocross class

[mean buzzen half dozen]

Hi,

just curious how they break down the classes of car to run autocross.

Are their 4 cyl, 6 cyl, 8 cylinder classes?



Thank you

No, here are the classes
Pro- either they have won an event or are a sponsor of the autocross
Street Machine- 1955-1972
Hot Rod- 1954 or older
Truck- well...they are trucks...and 1972 or older

It depends on the Organization, such as SCCA, NASA, USCA, Good Guys, American Autocross Series (AAS), Corvette, Porsche & other Marked Clubs, and Independent (Non-SCCA) Autocross organizations. Some small non-SCCA organizations, such bas AAS will mirror their prep categories (Stock, Street Prepared, Modified) and the classes along with SCCA's classes for some standardization. Most marked clubs do their own thing and usually will not mirror their classes and prep levels like to the SCCA classes. SCCA tries to class the various cars with other similar cars based on the type and horsepower to weight ratio, and the overall performance, hopefully to achieve a level playing field.

Oops, sorry. I can't tell which forum the posts are in because I look at the "Today's Posts" using the Pro-Touring mobile app.
