New Beefed up front A-arms. Provided in all Intimidator and Enforcer kits raced with foam tires these are much stiffer and just as durable as the front suspension arms we have offered previously. Some ask if these are better than a machined suspension arms and the answer is a multi-sided YES! These arms are molded with a blend of nylon, carbon and fiberglass materials to provide a suspension arm that is durable, strong, rigid, ligtweight, dimensionally tolerant and lest costly for the racer vs that of a machined arm from materials like Delrin.
