I hope I'm not wearing you guys out with all my questions; I appreciate everyone's input very much.

Here's my latest one: I am getting ready to start construction on my MkIV Challenge-configuration car (expect to get it sometime in mid-June), and will build toward an ST2 standard. What got me thinking about the topic referenced in the title was the desire to look ahead to optimizing the build as though I had the benefit of hindsight. One simple question which occurred to me was what my final dash layout should be - i.e., what gauges apart from the ones included in the package would an experienced racer want to have installed? It would be a pain to remove the dash, covering, etc. to redo all that. But, applying this more broadly, I thought I would ask you guys this general question: for those of you that run in the Challenge car series or in ST1/ST2/ST3, or in any other class, what would you do differently if you were building your car again? Also of value would be comments about what did you do to depart from the norm that you are glad you did??

Thanks in advance for your thoughts.

Bill
