willwood trailer hitch install help
 
1 Attachment(s)
I will try to install the willwood hidden trailer hitch soon on my car

there is a part of the document that is very hard for me to understand if anyone can chime in that would be great.

the paragraph starting by 'the standard porsche(05-10)...

It says "replace them with willwood heavy duty bumper bracket"... I did not get a part with such name in my kit, so I wonder if he talks about replacing the bolts or if there is a special part I am missing...

one more thing, if someone has the drilling/cutting template.. I don't have that either :(

I think it should look like this in the end :)

I found out on willwood page
http://www.willwoodsystem.com/hitch.htm

it seems only model 05+ require the 'heavy duty bumper bracket'

does anybody knows what was the change ?

I found this image

Is this what we are talking about ? may be one bracket is stronger than the other one ? I'd say the one on the right should be sturdier, no ?

I keep on answering myself with this thread
http://www.planet-9.com/cayman-boxst...ch-cayman.html

mike confirms the weak link is the new part is weaker and lighter, the older part (aka 'new mount' in the photo), is the one to get

this article has the parts number and all
http://www.planet-9.com/reviews/caym...den-hitch.html

It seems our cars until 2005 should have the older / stronger bumper shock absorber.

What are you going to tow?

philooo 09-15-2012 04:51 PM

I am planning on a small tire trailer for autocross, something quite light 700lbs max
250-300lbs trailer and 300lbs for tires and tools
a couple of guys have done this here on rennlist just not really well documented here I'll try to document mine a little better ;)

Are you hauling Hoosiers to the AX?

philooo 09-15-2012 05:17 PM

argh I wish :)

no nothing fancy, it is just that those sticky tires like toyo R888 or even michelin pilot sports heat cycle. So even if you don't wear them out that much, if you keep on driving them on the street the stickiness is gone after like 20 or 30 times you use them... crazy but true.
On top of that you want them inflated a different pressure, and it is a pain to have to inflate and deflate the tires 4 times a day each time you have an event.

Also I like to carry a bunch of tools just in case. it does fit perfectly well so far in my frunk but I'd rather have it all on a nice little trailer that I can just put aside when I go home and pick up when I need, instead of all the loading and unloading before each event.

not necessary but make life easier ;)

Try searching the GT3 boards. I thought I saw a posting over there - several guys have done it for hauling stuff to the track.

ok so I am at it.. but it is becoming harding than I thought.

First I wonder if I have the right part because the receiver hitch I have is not mounting vertically flush to the bumper metal beam.

Second about the wiring harness, I am trying to figure where I can find a good ground and positive switch input.. any ideas ? I don't want to run a cable all the way upfront to the battery :S

IMAGES:
- Car bumper less was super easy to remove.
- The old style bumper absorber
- the receiver slided in between heat shield and bumper beam (holes too high)
- the back of it showing it is flushed vertically
- the hitch pushed flushed horizontally
- the cut I had to make in the heat shield to be able to push the receiver tube into it.

philooo 12-07-2012 08:13 PM

For the power, I will certainly run a wire all the way in the front center console where I know there is switched power. I used to have my traqmate plugged there. I think it is a plug for optional telephone.

I am looking for places where I can tap my ground wire in the rear trunk area.

I know there is one on the right side of the rear wheel well, but it is a bit far. I am looking on the rear left side if possible :)

any ideas ?

Phil:

Question for you: are the brackets for the bumperetts bolted on or welded? I've thought about taking mine off for a european rear bumper but I'd want to be able to put them back on at some point.

Thanks!

philooo 12-07-2012 10:23 PM

It is not welded
But to access bolt you would have to remove the beam
I'll try to get you a picture tomorrow
