I have designed a replacement rear floor bracket that will provide the clearance necessary to accommodate aftermarket downpipes that would normally require permament removal of the factory brace. It will be made of a high cobalt tungsten carbide alloy in order to provide the necessary stiffness at the four places where it curves to clear the downpipes. It will bolt in place with the existing factory bolts and plastic sound deadening retainers. The bracket will fit the 2014-2016 E63 as well as the 2014-2016 CLS63. I am trying to gather a list of those members that might be interested in purchasing this item. I have zero pricing information at this point. Pricing will be contingent on the number of brackets I have fabricated, with the per unit price decreasing as the number that I order increases. PM me if you would like to be placed on a list of those with an interest in buying one.
