i believe its a torsion bar set like your typical 89-95 toyota and with the leafs in the rear its like doing a mini truck, me i would keep the leafs, im sure it'll need a step notch and that will go into the trunk. If go with the 4 link you'll hafta cut into the car for your upper bars to traverse. Dearched leafs would do the trick just fine or just remove a couple from the leaf pack and throw in a lowering block
