SPC Performance adjustable upper control arm kit for Audi B8 and C7 platforms is a four-arm set that lets you tune front camber and caster by ±1.5° for track-focused handling. The arms replace compliant inner bushings with xAxis sealed flex joints for freer pivoting and firmer response. Forged 6061-T6 aluminum keeps strength low-weight, with OE-style booted ball joints, 18mm threaded adjusters and replacement pinch bolts. Note: the stiffer inner joints can transmit increased road noise into the cabin.
