UMI Suspension is prior to them having a stage 4. Front coilovers with 3 hotchkis drop in the rear. Excellent kit. Billet specialties are 17x9.5 rear, 17.7 front. Overall the stance is one of the best I have seen, and excellent for the money. I can snap some shots if any are interested, my transmission is out of the car now as the front pump exploded on Friday. Just thought I would post for anyone interested in this setup.
