UMI’s Stage 4 kit offers a robust foundation for your street car designed for corner carving. It combines performance, weight reduction, strength, and comfort. Our dual tube K-member is recognized as the strongest in its class, capable of enduring wheel stand landings and street wear while still reducing weight and protecting the oil pan. The lower arms feature poly bushings on the straight strut portion to absorb road noise, while the non-adjustable uppers guide the suspension using greaseable poly bushings.
UMI’s K-member and A-arms are constructed from durable USA DOM tubing, precision bent, CNC notched, and welded in a jig, creating a solid base. Both upper and lower A-arms are assembled with high-quality polyurethane bushings and premium ball joints. The kit includes Viking front coilovers with double adjustable shocks, allowing for adjustments in ride height, compression, and rebound. Ride height adjustment is made easy with the included spanner wrenches and thrust washers. The compression and rebound adjusters can be clicked by hand—no tools required!—and offer a total of 361 possible valving combinations. The included springs are 550 lb/in, making them ideal for daily driving and corner carving.
