If you meant the photo that Ken posted - that is the factory hitch. No welding, it just bolts to the mounting points for the bumper shocks and additional points. If I built one, it would bolt on pretty much the same way, but would have a US-standard hitch receiver rather than the flat plate just behind the license plate. Much like Gary's - but I wouldn't hook to the aluminum bar for anything heavier than what Gary is doing.

When one shows up, lets do an auction for it. I'd like one too.

I'll bet there is a market for at least 100. I'd buy one with a 2" hitch receiver. I want to carry less than 200 pounds (total) of bike carrier and bicycles.

I'd buy one for a tire trailer. But then I'd have to find a suitable tire trailer. Hmm.

Got the tire-and-tools trailer, Rob. Yours whenever you need it. Problem for most of us urbanites is how to store the trailer between uses.

Brainstorming hitch options...

The tow-eye in the rear bumper is strong enough to pull the car. A hitch adapter that used those threads in the aluminum bumper beam might be cool for light duty stuff like the tire and tool trailer. Threaded pin to fit the bumper, a lock nut or lock plate of some kind to keep it from loosening in use would be needed. Box receiver on the aft end for standard attachments.

my thoughts as a "racer"....IF you have the rear bumper internals in could easily modify it to a trailer.....remember 928's are rated to pull 1500lbs without trailer brakes and 3500lbs with it....

while I wouldn't pull 3500lbs from a custom tow eye hitch....1500lbs would be easy....a 500lbs single axle trailer with only tires-tools is super easy...

I see TONS of "sports cars" at the track pulling little trailers....Miatas through Corvettes....

For only EUR 3343.00, you can get a whole shark with the trailer hitch already installed...

Am I the only one who thinks this is a very weird place to mount a hitch? A part that's designed to move, to "give" when hit by forces, and made of deformable aluminum?

Got one!
Roger, the 87S4 I bought last year came with a factory hitch. The documentation I have from the PO even has the specs from Germany. I'll scan and post later today. I'll take bids on my hitch! I don't think I'll ever tow anything with my baby. What do they go for? I could use a cash infusion (intake & TB/WP) on the horizon

You are absolutely correct about the "designed to move/bend when hit". However, I have been using that exact hitch - got the plans from Randy Faunce - for 7 years to pull a 4' X 4' trailer with 12" tires that weighs about 450 lbs including 4 Porsche wheels/tires and a tool box full of "stuff" to and from tracks. Furthest track has been ~850 miles each way, closest one is 250 miles each way. Most trips are through parts of the Allegheny mtns. NOT AN ISSUE ever. I did, however, use a much longer steel plate (~18") and 6 bolts that attach it to the bottom of the aluminum channel.

I have the tow eye installed, and a safety chain attached to each side of the trailer in front, as well as the electrical hookup for the turn signals and brake lights.

Rob/Bob, the trailer is one sold by Harbor Freight. They also sell one - or at least used to - that is 8' X 4', and folds in the center, allowing it to be stored easily. Another 928 track guy - Physics professor at a big 10 school - had one of these for his track stuff and his kids bicycles for several years.

A reader on this forum named Joe sent me a request for the plans for this tow hitch. I CAN NOT respond to the address that was supplied. Joe - please send me a Private Message.
