I've recently taken the Cayman R to autox and the track, and am planning many more autox and track days with both the CR and 911 this season. I've found some good info in this forum, but would appreciate suggestions regarding good books which cover topics like:

- Car inspection and maintenance before and after events
- Car tuning and mods
- Tire selection
- Track protocols (passing, flags, etc.) and safety
- Discussion of driving technique is fine as well, but I already have good books on that

Here are some books I found via an Amazon search, but none of them seem ideal for my needs (partly because three of them are British books, and the other is focused on racing):

 

Your sponsor organization should have a guide on flags, passing protocols etc. Most people have an indy shop do their inspection.

I found the following books to be worthwhile:


- Speed Secrets - Ross Bentley
- Inner Speed Secrets - Ross Bentley
- Speed Secrets 2 - Ross Bentley
