UMI Performance Stage 5 Handling Kits
UMI Performance Stage 5 handling kits include all of UMI’s high-end Pro-Touring products and will turn your A-body into a corner carving machine. Up front, the kits start with UMI’s awesome 4056-3 adjustable A-arm loaded with a 0.9 in. taller ball joint. This arm increases caster to around 6 degrees and allows road race camber settings with no shims. The lower A-arms are loaded with UMI-built Delrin© bushings for smooth motion and precise steering; as well as 0.5 in. tall lower ball joints to further increase spindle height and get rid of the factory bump steer. The 1.4 in. of additional spindle height transforms the A-body camber curve into something race-worthy. Viking’s front hybrid coilovers with double adjustable shocks 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. These bolt-on handling kits are available for a wide range of applications, including many Pontiac, Oldsmobile, Chevrolet, Buick, and GMC vehicles from the 1960s and ’70s.
