Does anyone know of a source, besides HRP, for ARB blade adjusters? I know that Team Autohaus (Merc SWC-TC team) converted to this "Proper" ARB adjustment/setup after 2 days on the Penske Technologies 7-post rig.

This setup is overly elaborate for a humble IT car, but it is easier to adjust. Not to mention you can install remote ARB adjusters for quick handling bias tuning during testing (obviously out of the driver's reach).
