Default How to attach a tow strap

Hi all,

I have two track cars that I use uniquely for going to track days/ to the circuit; one being a Subaru BRZ and the other a manual F-Type V6.

Stating the obvious: The BRZ has an infinite universe of aftermarket performance parts, the F-Type does not.

One small detail is tow hooks/ tow straps. I know there are threads on racing tow hooks on the forum, but I would like to open one on how to attach tow straps.

I have two of these at home:

Anyone have any ideas of how to attach them? Would I need to go to a machining shop and custom-build something with the same thread as the tow hook? Or are there easier/ more straightforward ways?

Grateful for input!

Best,

Jonas

The F-Type (at least the R) already comes with a screw in tow hook. It should be stored in the back near the battery. Loop the strap over the hook, done.

I get what your're asking, and I don't think the front frame/grill area is set up for that, as you've already determined. Adapt and move forward.

The tow hook socket on the F-Type is a reverse metric thread. Virtually impossible to find a machine shop that can cut reverse metric threads. There are some online tow hooks or license plate mounts that have hardware with threads that fit, but they are aluminum and for show only, not for dragging a 2 ton car. Your best bet is to install the OEM tow and loop thru the tow strap (if required) when you get to the track. Very functional but not pretty.

If I recall correctly, the black, rear (16mm), smaller of the two tow hooks, is not be to used for towing. Only the front silver tow hook (20mm) should be used for towing. Generally, the rear tow hook is not included with the car, only the front although in my case the black one was left in the trunk by the dealer. There is some speculation here that the rear tow hook is only used to strap down the car during transport to the dealership.

The pre-delivery instructions state to remove and discard it. My suspicion is that the place it attaches is designed for something like a 45 degree downward force and that if one were to try to pull straight rearward with enough force to pull the car it would damage the attachment location.

Perhaps a Bolt and Nut do the trick: DIN 933 SS A4-80 M20xLenght LEFT HANDED

Then can be welded something to the hex head or have custom bracket for the strap

It would indeed. That portion of the underbody isn’t anything more than thick sheet metal.

Thank you! Probably my best bet so far!

Yeah I believe you're right. I have a rear tow hook but I don't use it for this very reason.

I slapped a tow hook on mine just for grins. I could not find a LH 16mm bolt so I cut off the stock hook before the threads and then welded a bolt to it so I could mount the tow hook in the stock slot. Of course it is not

for towing but it certainly could be used to strap down the car.

Looks racy! Nice!

I probably shouldn't do that though even if it adds to the race car look as I wouldn't want the rescue team to actually use it should I spin off the race track. Which has happened a few times. Hrm.

My thoughts as well. Too tempting.

I've been thinking off and on about how to relocate the towing eye so I don't have to trim a P7 grille to maintain use of one. I started looking at universal ones of the correct length and "normal" threads but never got far with the search.
