Rob - I have the Addco rear bar on Winged1. Mine is one of the very early ones after the company decided to carry it. The effect that is has on handling is awesome, BUT ... it will crack the frame as currently designed. I have modified the installation significantly to lower the loads into the frame, and straighten out the attachments, but it still caused cracks on both sides under the engine. I have added some 5/16" thick aluminum/magnesium plates to the frame for reinforcement, as well as welded up all the cracks that started before the plates were added. I would not choose this bar for the foregoing reasons, as well as the fact that it cost 1 3/4" ground clearance as well. Now, I can't say anything other than ... I have plans for a solution for this. Progress will be based on the availability of time to sort out the design.
