I lifted my tire that much with stock (SVT) suspension
You mentioned possibly getting new bumper covers. I think that would throw you straight into SM. Mumm's site had some good info on weight reduction... I'm not sure how much (if any) items are STS legal though. Like swiss cheesing the front bumper.... or gutting the doors. Removing the headliner (if legal) should help a bit with the sloloms.
Good write up!
