UMI Performance 1998-2002 GM F-Body LS1 Front End Kit, Street- Stage 4 - FBS004-B
UMI’s Stage 4 kit provides a solid foundation for your street car used for corner carving duty. It features the best of both worlds with performance, weight reduction, strength and comfort. Our dual tube k-member is known as the strongest in its class and can withstand wheel stand landings and street abuse while still shaving weight as well as 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 on greaseable poly bushings. UMI’s k-member and a-arms are built from strong USA DOM tubing, precision bent, CNC notched and welded in a jig to form a solid base. Upper and lower a-arms are assembled with high quality polyurethane bushings and premium ball joints. Included in the kit are Viking front coilovers with double adjustable shocks that allow ride height, compression and rebound adjustment. The ride height adjustment is accomplished with the included spanner wrenches and thrust washers. The compression and rebound adjusters are clicked by hand (no tools!) and feature a total of 361 possible valving combinations. The included springs are 550lb/in and work excellent on daily driven and corner carving applications. Save $110.00 when purchasing these items as a kit.
UMI Performance bump steer kits relocate the outer tie rod pivot point which results in decreased toe change during wheel travel. Standard kits include sleeves, rod ends, jam nuts and high quality, direct fit tapered studs. Race kits require drilling of the spindle and include heavy duty 5/8 bolts. Race kits are recommended for autocross and road race applications while standard kits are indicated for street/strip use.
