Is there a way to shift weight from left to right?
 

Corner balance is almost perfect (FR/RL= 50.2%, FL/RR=49.8%).

But my left side (FL/RL) is 52.4% and right side (FR/RR) is 47.6%.

My understanding is the you cannot shift weight from left to right or vice versa. Is this 100% set in stone or is there a way to shift the weight? I don't have ballast to move (and have even read that that will not help) but was wondering if raising or lowering the right side a little would help? Maybe I should lower the right side ride height so it's "leaning" in that direction and thus carrying more weight. I am only thinking of 1/8" to 1/4" ride height adjustment. Nothing too severe. I do have some room to move because my ride height variance is currently 3mm or less per side. So a few mm lower/higher adjustment on one side is definitely within spec.

For starters....you can move the battery.
Then look at small things that can also be moved (empty the glove box).
Maybe bolt a piece of steel plate to the passenger foot area...or wherever needed.
Titanium bolts on the heavy side of the car...steel bolts (longer ones) to the light side.
Remove the spare tire?
In drag racing we did all these things and many more crazy ones ... helium in the tires....cement in the spare in the rear trunk...lead in the rear bumper...acid dip the whole car....paper thin fenders....etc.
Use your imagination.
