Alloy 910 seems to be very different from delrin.
Totally different properties.
Delrin is harder it seems where alloy 910 is definitely softer.

From reading it does indeed seem that alloy 910 would be much better suited to using as the door braces than delrin.
Makes me wonder actually @Dev... Could you not print smaller and better equivalents of the plastic TRD strikers?
So keep the TRD bit that goes on the frame, but replace the bits that go on the door with better alloy 910 versions?
Best of both worlds?

 The Mazda guys use delrin for to replace the rubber isolators that go bad in time. They found out using this stiff material greatly improved the rigidity of the car.

 I thought about Delrin but it would be a large undertaking of having a company mold and make them for our application. Then when it would come to fitment we would have a big issue with everyones car being a little different. After that the problem would be that we would have to drill holes in the door or frame of the car with a nuts and bolts operation. I cant imagine anyone wanting to go though all of this ruining their car in the process.
 
 Now you think about the our version of it. The material is stiff but also flexible at the limit and it can be mounted with double sided tape making it easy for anyone to install and also be adjusted. Sometimes simplicity is divinity.  Also sometimes people think its just too easy and rudimentary unless it involves some kind of complexity of design to be justified as anything good. Sometimes the simple solutions are the best ones and they are often met with a lot of resistance and controversy. In the end its easy to install and it functions.

I had a disagreement the other day on a social network with a bloke who was looking for interest should he decide to make some of what he described as "just a piece of plastic stuck to the door".
As he says it's nothing new and been used on the MXs for years, although he used Dev's YouTube video to demonstrate the fitment and use.
I suggested it was bad form and there was more to it than that but just got met with abuse...

  It doesn't surprise me. People like to look for complexity of what they don't understand to justify something of value. If it looks easy it will be criticized even if it works but they may not understand what goes into it. 
I had a few critics that went out of their way to demonize the modification when I was developing it and behave badly in a mean spirited kind of way.  I always see stuff like this as being a good omen and once the reviews came I sold many sets.  There was a lot of thought that went into making it simple and cost effective so that I would sell and it exceeded my expectations. If I could make it even more simple and bring down the cost I would have as there is no point in taking advantage of a community, im a hobbyist first. As far as the critics go it comes with the territory.

Sorry about that. I wanted to show the mx-5  product that our bushings were loosely copied from. If you notice they are relatively in the same area. The mx-engineinwrongplace  owners had a significant result and that was what I was aiming for. They also have some compromises in opening and closing the doors so its not exactly perfect but the yield in results makes it worth it.
  Here is a picture of the Delrin bushings for the mx-engineinwrongplace

 That was actually my first thought when I decided to see if I can make my own. I actually did try to use filled  plastic spacers but its just not possible. Also it would be dangerous if there was any interference with the lock mechanism. My primary concern was safety.

 If you look at the TRD part it is spring loaded and moves when it the ramp plastic pushes against it. The design was just to complex to replicate. The Mazda MX-5 solution is much better in my opinion. There is a lot I don't understand about the door bushings and its possible some of the insulated felling people get might actually be some kind of hard spring damping action that makes the car feel insulated. I always thought about how this could be improved and there is just no other way based on the fact that they work quiet well.

I have the TRD hinges. It was debatable if they actually work and I felt that they did. It is what inspired me to make the door bushings. The TRD piece is a very neatly made and very high quality part but there is a big downside. That little plastic ramp that attaches to the door does not hold in well and pops off.

I had this problem on left doors only. I disassembled  everything and clean up mounting points. And it fixed the issue. Just in case I bend a little this metal clip attached to door.
