Picked up #0173 this past weekend. Been slowly going over the car, and I've found that the rear wing hardware seems to be in need of attention.

The hardware holding the uprights to the car seems fine. The torx screws holding the horizontal plane to the uprights have these plastic/rubber washers that seem to be in various states of disintegration, leaving the wing slightly loose upon closer inspection.

Have any other owners noticed an issue with these?

 

Also found a cross-threaded nut in the rear wing, which I'm going to have to re-tap.

Excuses to buy tools are always wonderful.

 

Wanted to post an update to this. Replaced the OE hardware with some stainless metric hardware and plastic screw caps, and works better than the stock plastic washers.
