Default Corner Balance & weight on 911

What are typical front/rear weight distributions on an ’86 911 (F class)?

Where are some easy spots to legally loose weight in the car, especially in the rear? I am right at or slightly above weight now with no ballast.

I have already done:
1. spare tire
2. heat exchangers
3. radio and speakers
4. race seats
5. added roll cage
6. front/rear fiberglass bumpers.

... and yes, I know a personal diet would help this year.

Actually cars are weighed with driver, they add 150 lbs to the stock weight. If you weigh above this you have free ballast to extract. If your having a hard time getting under weight, then Jenny Craig is an option.

I am a little over 200, but tall so I don't need to lose any more than 10 lbs off of me.

Doug - thanks for the sites. Very helpful.

Still wondering about the front/rear weight percentages...
Is for 40/60 way off for a 911 race car?

Plan your fuel loads also. How much fuel is in the car when you weigh it?

Is this for PCA club race? If so the cars are weighed at the track without driver or drivers personal protective gear.

The car is about 25 lbs over weight with me and 1/4 tank. That would put it pretty close if it were empty. So I can take out a few more pounds and and just not run it dry.

They do weigh the drivers with the car in PCA this year.

I am more concerned that the rear weighs more than I want it to.
