First priority is to get lighter, to reach the minimum weight rule. This is most important.
Second priority is to get more left-side percentage. Is there any ballast at all on the car?
Third priority is to increase track width. Don't be surprised if a track width that is less than the 82" max gives you better maneuverability to pass someone in the middle of the turn (in a traffic situation). Also, the wider the rear axle, the more tire drag that might be created in a tight turn.
Also, don't be surprised that a narrow track-width modified on "hard" compound tires might be faster on a short run (gets more heat into the right side tires quicker, getting them up to best operating temperature).
