i don't know yor track conditions but if it's tacky i would be looking for around 48% cross and 52% rear. if its dry slick i would increase cross by 3 to 4 % set your car up for what track condition you see the most and adjust off of that. scale your car but don't go wild trying to get your %s your generally better off with close %s and less weight.

Here's a rough idea.....

FLAT TRACK
52.5% left
56-58% rear
49% cross (lr + rf)

HIGH BANKS
52% left
54 - 56% rear
51.5% cross

try starting with around 80 lbs. of wedge in the car (the lr 80 lbs. heavier than the rr).

If the car is tight, lower the wedge keeping the other %s as close as you can. Maybe by taking 2 turns off the lr and adding 2 turns to the rr, or depending on what type of car you have, with lowering blocks, to loosen the car alittle, add a 1/4" block to the lr, and take 1/4" block out of the rr.
The same could be done with stagger as well.
