Starting with factory fesh GM knuckles & ball joints, we CNC machine a new outer tie rod pickup point that can accomplish 70 degrees of max steering angle if other constraints are lifted. We've thoughtfully clearanced material around the tie rod (with CAD modeled 3D surfacing) considering full compression and rebound travel. Compatible with OEM tie rods for a tight and reliable taper fit. 30mm or 1.25" wheel spacers are recommended on a basic wheel size like 18x9.5+40. Ackerman is 7 degrees. Some clearancing to the front lower arm and a bump stop near the caliper mounting bolt is helpful to achieve greater useable angle with stock arms. This was thoroughly tested on Matt Field's street C6 at Sonoma Drift Winter Jam 2018 where he inspired everyone by keeping up with pro cars on the track using his fixer-upper base model sourced for ten grand modestly equipped with only our hand brake, coilovers, borla exhaust & a tune! #LetsJustDriftVettes
