One of the most cost effective and substantial suspension modifications you can make to your Porsche is replacing the stock soft rubber lower control arm thrust bushing with our adjustable solid version. By replacing the rubber bushing with a solid version, not only do you reduce unwanted suspension movement which results in dynamic toe and camber movement under heavy cornering, but you also add caster adjustability. Increasing caster, particularly in the front, improves suspension geometry such that more camber is gained when the wheels are turned. The addition caster allows for less static camber, thereby reducing inner tire wear (particularly in street applications). Additionally, added caster gives your 911 or Cayman that added steering weight which is essential for optimal steering feel.
