Who says you can't have it all? UMI's Stage 4 kit transforms your Chevrolet into a handling machine with the adjustability to perform well at the strip or haul your family comfortably - to the autocross. Up front we start with UMI's proven upper and lower tubular a-arms loaded with 1/2 inch taller upper ball joints. The upper a-arms increase caster, without additional shims, for a precise steering feel and straight line stability. The lower a-arms are loaded with UMI-built Delrin bushings for smooth motion and precise steering. 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 inch chromoly handling sway bar. Out back we stiffen the chassis with adjustable tubular frame braces which stabilize the Poly/Roto combo lower trailing arms and fully adjustable Roto-Joint upper control arms. 1 inch 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 inch 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 inch holes). All UMI components are manufactured with pride in Philipsburg, PA - USA.Features:Increased spindle height by 1/2 inch via tall upper ball joints for improved camber gain and a better contact patchUpper a-arms add caster for improved steering feel and straight line stabilityLower a-arms feature UMI-built Delrin bushings and accept standard springs or coilovers1.250 inch front sway bar for flat cornering, CNC bent from 4140Double adjustable Viking shocks are hand assembled in Minnesota, USA and feaure 361 possible valving combinations.
