Actual selection (3.5 Vs 3.9 etc) should be based on the track/s you will most frequently race on. I have a great gearing/speed calculation spread I can share with you if you want to work out the best ratio. PM me with your E address if you want this spreadsheet.

David - Kel's comments are dead on - a 2.00 is very odd, especially for the Penske cars. How did you validate the finding?
