When you build a proper lightweight your problem is certainly going to be too little weight up front, not too much.

First, realize that if you remove weight equally front and rear you're actually increasing the rear weight bias. IE a remove 200 lbs front and rear from a 950 front/ 1450 rear car and rear weight bias moves from 60% to 62.5%.

It's also much easier to remove weight from the front- fiberglass hood, fenders, bumper, lightweight battery, less fuel, no spare, 935 front suspension, etc. It's very tough to remove similar weight from the rear. In my experience it's tough to get good turn-in, etc with more than roughly 62% weight on the rear.

My suggestion would be to pull weight where you find it but with a focus on the rear; you'll still find the distribution will move rearwards. After that if you want more rear weight bias relocate the battery to behind the seats- this alone will move the weight distribution by ~1%. Unless you have very fat rear tires, however, I'll bet you it'll handle worse...

Pete...you've obviously given this some thought. How does weight distribution affect your tbar/sway bar decisions when you start jacking around balance?
