Just starting out, been reading the threads have a few questions. I want to build a extended wheelbase car. From what I have read I think I want to place as much weight as I can as far back as I can. With that said do I want to shoot for a COM of 1/2inch to 1inch in front of the rear axles? Do I want to place the front wheels as far to the front as possible? What about raising one of the front wheels?
What I am thinking right now is having a COM of 1/2inch in front of the rear wheels. Front wheels move as far to the front as I can. Am I on the right track? Thoughts? Suggestions?

Yeah, you're on the right track. Longer wheelbase (move front forward, back backward) is usually better. Watch your 7" length limit. COM of 3/4 is more realistic, unless you have a very smooth track and multiple test runs. Raising a front wheel definitely helps, and it simplifies your alignment process. When is the Big Race?

Big race is in about a month, so I have time to pay around, I'm sure I will screw up more than a few pieces of wood. Been in a few races in the past, tired of coming in middle of the pack so this year I took to the Internet to do some research.

I LIKE TO PUT MY WHEELS 5/8 FROM THE REAR AND 3/4 TO 7/8 ON THE FRONT.GO WITH 3/4 TO 7/8 ON YOUR COM IF YOU DO NOT HAVE A TRACK TO TEST ON.RAISING ONE WHEEL WILL HELP A GREAT DEAL.SOUNDS LIKE YOUR ON YOUR WAY.BEST OF LUCK HOPE THIS HELPS.

You have some good advice here. Be sure and use tungsten weights if you want to get that aggressive on the C.O. M. I find it very difficult to get to 0.6" even with maximum use of tungsten and still keep the weight low on the car. Try to get weight concentrated as much as possible in one area not spread out.
