SPC xAxis adjustable upper racing control arms are a four-arm track-ready set for Audi B5/B6/B7 A4/S4/RS4 and VW C5 Passat platforms, allowing camber and caster adjustment ±1.5° on both sides. These arms use xAxis sealed flex joints to replace compliant inner bushings for a more reactive pivoting joint, and are forged from 6061‑T6 aluminum. Note: the racing-style flex joints may transmit additional road noise compared with OE bushings.
