b'GM F/X AUTOX-STARHow Does Ron Create These Setups for Different Applications? There are six suspension pivot points on each side of the front suspensiontwo for upper control arms, two for lower control arms & both ball joints in the spindle. We cant keep the OEM pointsdesigned for 60s & 70s passenger carsand win races. We need to relocate at least four of these pivot points to achieve the optimum geometry we want. Ron designed our Track-Pro spindles to use the most popular racing ball joints with 12 different upper heights & 13 different lower heights in .100 steps. We completely remount the upper control arm with our AXT-STAR brackets for significant change. Lastly, RSRT precision slugs allow Ron to fine tune the upper control arm mounting heights & angle in nine positions, front & back, in .063 increments. Our new AXT-STAR Centerlinkwith modular inner mount blocks & 25 position slugsallows Ron to put the inner tie rod pivots almost anywhere he wantsin or out, up or downto achieve beautiful bump steer curves never before possible. These parts are tools for Ron to create optimum suspension & steering geometry that produces awesome grip, handling & turning characteristics.
