ladder bar suspension.

The biggest reason for adding ladder bars or a four link is to gain additional tire clearance for big tires. I wouldn't bother adding ladder bars or a four link without back halfing the car, it's a waste of money.

Save some more money, back half it with a four link (then you get all the adjustability too) it doesn't cost that much more than a ladder bar setup. Add some 14/32's or 15/33's and you'll have all the traction you'll ever need.
