One of the most common problems with the ageing E46 3 Series and E85/6 Z4 is the worn lower control (caster) arm bushes and ball joints. As it's a gradual deterioration, many owners don't notice the classic symptoms of poor turn-in response, soggy feedback during cornering, and decreased braking performance. Febi-Bilstein offer this set of aluminium front lower control arms with the caster bushes pre-pressed onto the arms, allowing for a simple and easy installation. This set of Sports control arms have been manufactured as a direct replacement for M Sport arms, and features stiffer ball joints to improve handling and braking response. These are a great upgrade for all E46 3 Series and E85/6 Z4 models, and will fit regardless of whether your car was optioned with M Sport suspension. Made in Germany.
