UMI's new Stage 5 kit includes all of our high-end Pro-Touring products and will turn your A-body into a corner carving machine. Up front we start with UMI's awesome 4056-3 adjustable a-arm loaded with a 0.9" taller ball joint. This arm increases caster to around six 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" tall lower ball joints to further increase spindle height and get rid of the factory bump steer. The 1.4" of additional spindle height transforms the A-body camber curve into something race worthy. Viking's front hybrid coilovers with double adjustable shocks ​allows 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 front is completed by UMI’s 1.250” CrMo handling sway bar. Out back we stiffen the chassis with adjustable tubular frame braces which stabilize the double Roto-Joint lower trailing arms and fully adjustable Roto-Joint upper control arms. With our 2999 axle housing Roto-Joints, we end up with full articulation in all 8 locations. 1” or 2” UMI rear lowering springs are controlled by Viking’s double adjustable rear shocks, once again featuring 361 possible combinations. Rounding out the rear is our ​three way adjustable 1" tubular Pro-Tour sway bar. This handling sway bar attaches to the axle housing and also to the rear crossmember for a bind-free system (requires drilling four 3/8" holes).  As always, this kit features UMI’s quality red or black powder coat and premium hardware. All UMI components are manufactured with pride in Philipsburg, PA – USA.
