Yes, I've looked a little into it:
A modification I've got an eye on is to use parts form a different C-series transaxle to get either a taller 5th gear or do a 6-speed conversion with a realy tall 6th gear from a diesel.
I expect some not insignificant gains as the 5th gear is rather short in the Spyder, causing it to rev almost exactly 2900 rpm at 100 km/h.
And it's not like the TÜV checks the casting number of transmissions, so that should be fine.
But it would be a lot of work as I'll need to find a donor gearbox and convert it with parts of mine and just getting the gearbox out is a rather complicated process...
