So i see that the weakest point is the welds on the two side flaps that hold the beam that is horizontally across the car. I understand that welds are strong, But if the welds fail the tow hook will fall off correct?

im looking to get a tow hook in the future, i want to haul kayaks lol

I would say yes, that's probably the weakest point, and yes, if they were to fail, the chains are going with it. I'm confident in the welds. They're a strong corner weld (the pieces were fixed both outside of the corner and the entire corner was filled, then welded again on the inside). Also, the cross beam is very close to the bracket so there is very little lateral force on the tabs. If there was about another 1/8" of clearance the cross beam could be welded directly to the bracket without the tabs. :\

kask2_6.0's hitches have will gussets for additional strength here. I decided they weren't necessary for mine.

I want to tow my jet ski, clearly that may be to heavy for this, any idea on making a stronger one for heavier tows. Clearly we cant tow a boat, but a jetski , or small utility trailer probably can be done. Thoughts?

With some additional gussets I think this design is probably about as strong as it's going to get. Maybe gusseting from the bottom of the receiver back to the mounting brackets. Ideally a lateral piece would help but I really don't know where one could go. I installed my Perrin catback last night which opened up the back a lot (I now have about 4" of clearance), I'll poke my head under some time this weekend and see if anything jumps out.

I'd estimate my trailer weighs about 150lbs, wheels/tires 200lbs, and the rest of what I load for autox another 100lbs. So probably a little under 500 total. The car tows it just fine. It's noticeable when starting from a stop but not so much while driving.

Thanks for the kind words qoncept. Hitch looks good.

How has towing been so far? I'm about done fabbing my trailer to fit 2 dirt bikes. It will sit 8" from the ground, use my stock brz wheels, and have about a 50 lb tongue weight. @ScoobySouth will also be testing the hitch in the next couple weeks for more input before making the final version.

So far so good. Backing it up is an exercise in patience - once the trailer starts turning its almost too late to counter steer. Might end up putting a longer tongue on it. The car doesn't mind the load, though, and I can brake as fast as I'd want to with all that behind me.

Yeah, maybe that's the reason.... i'll check at home (sounds like a problem on my end).

FYI, kask6_2.0 has begun taking preorders for his hitches. Very reasonable price and lightweight. http://www.ft86club.com/forums/showthread.php?t=40098
