I agree that suspension arms are not certified to ADR's. Instead an engineer will inspect them to make sure that they are safe. The easiest way to do this is to use a mass produced part such as the Jag A arms. If items have been modified then an engineer is required to make sure that the modified part is safe. As I understand it, the engineer inspects the mod, usually takes a drawing of the mod and does some calcs to make sure it's safe.

For example, my RCM uses shortened Jag suspension front and rear. The front end has been cut and shut some 150mm. The engineer is only concerned that the cut and shut has been done properly. As the front end retains the factory geometry, then he is happy.

Perhaps part of the problem that Cobra.au has could be a manufacturer has adapted a mass produced part, such as the Jag A arms, and has not fitted them to a factory specification as the part was designed for. That's what I like about my RCM as it uses the whole front end. Despite the fact that it has been shortened it retains the factory geometry which Jag spent huge dollars to develope. No cobra manufacturer has the resources to do the same. It makes me a bit weary if/when a manufacturer claims to have developed a better front end that is based on a factory part.
