Get ready for the track with this four (4) arm set of adjustable upper links for many Audi models. This kit has four arms so you can change camber and caster ±1.5° on both sides. xAxis sealed flex joints replace the overly compliant inner bushings with a free pivoting minimum compliance joint. You will feel the difference in handling. Warning: You will also hear the difference, the OE bushings are designed to absorb and negate noise, vibration, and harshness (NVH). This set of arms will transmit noise into the cabin.
