Quote from: Gibla on August 31, 2022, 21:16Ps went out this evening with an unmodified in any way (minus any upper strut brace) Fl on ~45k miles with a 15-month-old Dev 'bar of soap' installation - roof down Zero detectable scuttle shake, no rattles whatsoever ......perfection but in the act of going out in that car I had to shift another car, the bloody doors were stuck shut after this morning's re-installation of the Dev units ......will take 'em off asap + thin them down
Quote from: Dev on August 31, 2022, 21:27Are you using any Carnauba paste wax with the install. It is needed when they are installed otherwise the doors will be tight and hard to open. It makes a very big difference. After some time they will reconfirm to the door and it will not be required depending on how tight they are to begin with. The material I use has the ability to adjust over time as it compresses. In your case if you haven't use them in a long time they will expand back to its original shape. Cheers Dev I will take the advice + do as you suggest
Quote from: Dev on August 31, 2022, 22:07Just a few corrections. The door bushings I manufacture are made of Alloy 910 not Delrin. I initially wanted to have them made of Delrin like what is offered in the Mazda community but it was not possible due to the increased costs. I substituted for a newer printer material that is very strong but also flexible because that area takes a beating that cracked my prototypes made of solid ABS. It turns out that the Mazda community found out that Delrin was not a good choice and have switched to carbon fiber reinforced nylon long after my bushings were manufactured. In my opinion I believe Alloy 910 is the better material because its stiff but it also yields and comes back to its original shape and will confirm over time with a break in period of about six months to a year if they are under constant tension. This material has the ability to be sanded to fit or you can add a shim to tighten them up however over subsequent generations of printing I finally got the right size where in 90% of cases adjustment is not necessary. The installation is easy and requires no hardware and can be removed easily if you don't like them. Although I could have made a more elaborate set up my goal was to keep costs low and installation simple for the most bang for the buck and volume of sales. That goal was achieved long ago. It is nice to see a new more refined option and I wish them the best of luck.

Quote from: Gibla on September 16, 2022, 05:14So whilst in pre, mid, and post selling of cars + swapping bits around to suit myself I came up with the following conclusions (but not exactly comparing like for like as some Fl + PFL along with different tyre/ suspension combos.) FL with Devs + JS inserts removed, but still with Carolynne strut brace = inferior to when 'full monty' present (the black car that has now been sold)FL with Dev + JS inserts installed but awaiting strut brace = not a detectable difference to 'full monty' (the yellow car that is getting strut brace installed 16/9/22)So my conclusion from that is that the combined inserts are certainly helping appreciably :- this is both with and without cf roof present or not. This doesn't mean the strut brace is ineffective ...far from it, these unscientific offerings were from the pov of scuttle shake and a feeling of solidity, not from a cornering prowess aspectAs from today though there will be no opportunity to replicate or do further testing as my MR2 # have been culled to 'just' 2 and both are 'full monty' ie with inserts + bracing. ps Another 'finding' was if Dev insert only = close to a 'full monty', from memory I had a JS only arrangement that always was in combo with a strut brace = good , but no direct comparisons as many months apart . The issues I had with the Dev inserts were sorted out with the Carnauba paste that was suggested by the man himself, but one set (no longer in use or in my possession seemed to be vastly thicker and readily would cause opening issues in all weathers)
