im running 7-5-2
going down in the center will make the car a little easier under power out of corners.
also, i think im a little lighter on the shock oil and im running purple springs in the rear with the purple sway bar.
I do not limit the steering, but if its twitchy go up to maybe 10,000 in the front diff.
Also, if you can add some weight to the rear that helps A LOT!!
