track chassis setup

[r lane]

I track a 78 911. With me and fuel in the car, I am on the scales with values being approx 25lbs heavier in the front left and 40 lbs in the left rear. Ride heights within an 1/8''. That gives me a high 48, low 49 split. Torsion bar car. I am turning both left and right so thinking one wants the car as unbiased as possible. Tracks such as Road Atlanta and I am told Road America, are more a right turn tracks than lefty. So I am wondering if putting wedge into the car is advisable, jacking from right front to left rear. Any of you guys wedging. Would appreciate your input. Thanks, Bob

If you have too much left side weight, a wedge adjustment won't change that. You'll have to physically move things around the car, or add lead. Or add wheel spacers to the left side. Or change the wheels on one side to a different offset.

If you have not already done so- Relocate the battery to the smugglers box.

There is no way to not have more drivers side weight than passenger without substantial added ballast. What is considered too much left side weight? My battery is as far forward and right as I can get it. I think excepting an odd or extreme circumstance, reduced centriffical force (less weight) is more advantageous than any advantage you get from ballast. I don't know that, and a subject for hot debate I am sure. My specific ponderings now are, are guys wedging their 911s on road courses and seeing gains.

What are your goals? To win races or to have fun at DE events?

I think a lot of people only interested in the latter vastly overthink things like this. I know I used to. Then I remembered my ultimate goal - to have fun at DE events. That made things a whole lot simpler. And cheaper.

Moving weight around to balance things is good to do L/R balance, keeping weight low, and minimizing polar moment where possible., Like putting the battery in the passenger footwell or smugglers box, doing a front mounted oil tank, etc. And then deal with the fact that L/R weight probably won’t be equa.

I wouldn’t usually think to add weight to a track/race car other than to make a minimum. Usually when corner weighting, you look to have equal cross weights, or at least that’s what I’ve done. I haven’t tried adding wedge, it may be beyond my capabilities as a DIY, self supporting racer type.
