Are the PCA AX classes listed online any where? If not what class does a stock 4cylinder 1.8 914 run in and what can you do to the car and still remain stock? Shocks larger front sway bar?

You need to find out what rules your region follows. If you are going to use Concours rules use this:

The 2005 rules don't have a 914 in the Showroom Stock Class. They do have the 914 in the Production Category P2. Look at Appendix V for a list of modifications that are allowed. It refers back to the main doc.

Thanks for the link

Most PCA regions have their own websites and can be seen at www.pca.org click on regions and they will be buried in there somewheres......
