Because this topic has been brought up several times recently let me make a suggestion. We really need two sticky threads: "Autocross Setups" which would have posts only by those who wish to document there setups and brief comments. The second thread "Autocross Discussion" would be a general discussion about the topic.
Of course specific question threads could be opened as needed. As a veteran autocrosser I'd like to keep my research to as few threads as possible. I'm new to the SG so I'm just looking to channel the insight of others.
