This kit of four adjustable upper control arms will allow +/-1.5° Camber and/or Caster change on your Audi. These arms directly replace factory upper fixed-length arms, allowing easy adjustments after installation. Engineered for both street and track use, forged 6061-T6 aluminum ends with large 18mm threaded adjuster links assure a high strength kit. Maintenance free ball joints and bushings provide factory ride, handling, and great performance.
