OK - I tried my spin at this. I attempted to use a standard Thule fork mount long tray and existing hardware I had laying around. I got as far as mounting the tray to the supports. Big problem with the Thule tray is that it is not stable - the tray twists as you rock the bike forward and aft. I reinforced with strip of steel with no luck. I tried angle iron and the stock tray is still too flexy.

I think to make this work, you need to use a welded, custom-made tray that is stiff.... I noticed that the boxster example above, you need to reinforce the fork mount directly. You cant have it isolated by itself.

If you have any ideas let me know. I figured Id post my failed attempt so others dont repeat what I was thinking.... As far as the mount to the bumper - I think its working great. It seems stable using a u piece of steel with angle bracket.

Maybe it needs a rectangular section metal bar cut to the same length as the Thule rack and going across the two supports with two bolts attaching it to each support. Then the Thule rack goes on top of the rectangular section metal bar. That way the fork mount has something to mount to underneath.

Using two bolts to mount the rectangular section metal bar to the supports should be much more sway resistant than a single bolt.

If you can find someone to weld up the joints that would make a big difference too.

I also use a strap with one end around looped the seatpost and the other end with a rubber coated flat metal hook attached to the edge of the trunklid just below the rear windscreen to keep the bike from rocking back and forth.

I think your suggestions would work. Ill try it out.

I actually have 2 bolts where it mounts to the car. The first one in the new drill hole and Im reusing the original one in the back to stabiliize swaying.

Have you had any issue with heat? Seems like my fork is pretty close to the tailpipe...

Yeah, definitely use a closed section member, like a rectangle to resist the torsion.

No issues so far concerning heat from the tailpipe.

Cool

It's a great idea, thanks for sharing!

I would go very easy on the gas though:-)
A lot of lateral stress could be applied to the bike's front fork.
I would somehow run a strap from the top of the bike's frame to the car.
Damn, the shopping cart handle of the early 993s could have a purpose after all!!!
Although the spoiler would get in the way at high speed...

Wow that's pretty ingenious... Quick question for those of you that are messing with this - do you think the bumperette bracket would be strong enough to support a fabricated hitch system to tow a tire cart for the track junkies out there?

there's a local boxster driving dude that does just this.
just design the trailer to keep weight to a minimum
