So, I am considering making a run of forged steel, heat treated Syncro's with a Carbon friction surface for the Spit / GT6 transmissions, you know parts that last more than one weekend and probably last a lifetime comparatively speaking. The questions is, is anyone interested? They will be expensive, probably $75ish each depending on the size of the order I can place. I should have some available for testing in the next 60 days or so.
Secondarily, is there other Triumph transmissions that have syncro issues or is it just the Spitfires?
If you are interested let me know how many you would like and I will start a list.

 Yeah the Big-TR is a candidate, the problem is largely the (lack of) quality of the replacements on the market today...

Most gearboxes I assemble these days have good, used OEM syncros 
installed, I have been having good results doing that. I did put a set 
of the Bastuck (German made) syncros in my Stag street car, the gearbox 
shifts fine but I don't drive that car even remotely aggressively. I 
didn't realize anybody was having issues with those German syncros. Am I 
missing something?

The original synchros were good but as the brass "grippers" wore down, 
they would not slow the gears sufficiently enough.  We fixed this years 
ago - just face the synchro about .010" or so.  It buries the synchro 
deeper onto the cone and in essence you have new "grippers" on synchro 
ring. Ted

dont forget, a f good part of the "syncro problem" in all these gearboxes
is worn out mating outer sleeves, gear tapers and dog teeth

the "big" gearbox in TR's, Salons & Stags all have much the same issue, and
you might find an even bigger application/market there

Most of the repro syncros ive seen for the "big" box are worse than worn
out factory ones. The most common problems ive enountereed are wrong brass
used for the backing, wrong cone angle and wrong dog teeth shape, with a
few even being badly out of round, so doomed to failure.

whilst ive not been doing such repairs commercially for a few years now, at
the end of my triumph gearbox building career, we were dismantling dozens
of old gearboxes just to raid 1st and 4th syncro rings and move them into
other boxes needing 2nd and 3rd. this was better than the new ones on offer
at the time from vendors like Moss, Rimmers etc and even some of the UK's
specialist transmission parts suppliers (basically, the people making them).

ive had a fair bit of  recent experience with coated syncro rings in late
model Toyota gearboxes in race applications. . The factory coating has gone
thru several iterations , some of them not very good at all, so caution on
this front also.

our race Lotus has syncros supplied by a US firm
https://synchrotech-transmissions.com/carbon-synchros

keep us all informed please. US$75 is not unexpected or unreasonable  for a
boutique order, if they actually work!. The Toyota gearbox
"carbon" syncros currenty retail for about US$45-$50 ea

I used to rebuild transmissions for members of our local club. The 
owners always wanted new stuff so I kept a lot of used but still good 
synchros. That's one way to get good parts from your racecar.
