Yes, but he does not want to lower it anymore for street driving reasons, and if he did then I believe the roll center would drop more than the CM would, therefore increasing the roll couple since the tires would be a tiny bit grippier and the lever arm to the CM would be longer.

If he is being unsettled as a driver by the roll, then the car is too soft, even if that means the car may sacrifice some grip. (It could be a wash due to the camber changing less.)

He initially said the weight transfer was too quick but I cannot be sure if he has correctly diagnosed his problem (no offense Jim). Many pro drivers can't tell engineers what they want to know but they are retained due to natural talent. I believe Senna fell into this category somewhat. The true greats like Mark Donohue can engineer their own cars, of course, and the good drivers know how to talk to the engineers.
