CM on a Best Track

[derbydad63]

Hey, does anyone have any input on cm relative to track configuration?... we are used to racing on an aluminium track with a gradual slope (probable 8' radius, 40' length) and have a challange race for charity and they are using a best track with the steeper drop and 4' radius curve to the straightway (also 40'). We are used to designing CM around 1 1/8"... Keeping in mind the sweet spot of 1" - 1 1/4" in front of rear axle I am wondering if my cm can be little closer to 1" on the best track config or if we are better off moving other direction towards the 1 1/4" given the shorter radius and seemingly sharper curve. We use extended wheelbase and only enough pine to hold wheels and weight. No weight behind rear axle and tungsten to keep mass centered.

New to the board and appreciate the help!

Our Pack and District use a Best Track. Last year our CoM was .9" or so. This year we are going for 3/4". Get aggressive on that Best Track, especially with the extended wheelbase.
