[note - not even a tech
inspector anymore, but I believe this is accurate] Come pretty early, and plan to stay for a couple of hours. You will want to see all the wear issues with other similar cars (what do you drive? - unless it's a CarreraGT or a purpose-built early race car like a 904 (drool), there will likely be others like it). You will learn A LOT for the time you spend. Whatever you do, don't come late in the session.
Also, why not introduce yourself
here. We generally like first names and photos of your car.
