I had our 2020 Plus Six up in the air today for underbody inspection before we take it to France. So based on the two rear rack anchor point failures seen on the Plus Fours I decided to take a quick look at the brackets. Although the rear rack on the Plus Six sits lower than the Plus Four ( no spare wheel ) the same lower rack anchor point design is used. It is apparent that the part that is breaking free on the bracket is only welded from its rear, in Jens photo you can see that there is a female slot machined in the section that is still bolted to the car and a corresponding male slot is used to go into it on the part thats broken free, the only weld holding the two sections together is the weld across the rear of the slots. The two parts need a fillet weld down each side and the rear slotted section needs a more substantial weld across its back, that would make it very strong. There are two Hex headed screws that hold each bracket to the rear of the subframe, I believe the rear valance has to be part removed to gain access to these. The valance is held by bolts each side in the wheel arch and I suspect a series of bolts internally holding the rear valance in place. On the Plus Six its looking like the rear circular closure has to be removed ( spare off on the Plus Four ) to gain access to these.. Also there are wiring runs behind the rear valance for the number plate/fog/reversing light. As our Plus Six is now out of warranty, its looking like a winter job for me to reweld the stainless brackets. Luckily I have the SS rods and the welding kit to do it.
