I remember a thread talking about getting hardened gearsets where someone came in and pictured a few of the several gearboxes he/she had ruined.
I specifically remember though that at his/her power level you didn't need to change into it badly it just went at the torque level he had.
If this wasn't sonofthehill whoever it was would be a perfect candidate also.
As someone keenly interested in this topic and home-brewing strengthening options, Ive been searching fruitlessly for pics of internals from failed 5sp boxes. Would love to see some.

No, I have never broken 4th in any of my 5 speeds. I have not broken any at the track yet either, always on the street, in 2nd, 3rd and 5th.

Here is my most recent carnage, I didn't open this one but this is definitely an input shaft tooth, matched it to a different one. I did manage to keep the input shaft from moving forward and sheered the whole tooth(I think), I had only sheered approximately 90% of the teeth previously.

I will email them today, I have an unusually busy day though.

Technically, you can reduce the likelihood of breaking an input shaft tooth by 50% simply by removing every other tooth.

I see no fault in that logic

Except that even with only one tooth removed, the car becomes almost completely undrivable.
