I really enjoy my 355F1 on the track.
Although I have driven quite a few manual cars on the track, IMO the F1 transmission gives you an advantage, as well as no mistakes!
I have had no problems with it at all. I did replace the clutch once in it's 1st major service at 28,000 km but it was only 50% worn.
I have since just had the 2nd major sevice at 46,000 km and they did not need to change the clutch this time. Driving on the track does not hurt it, it is stop/start traffic, reversing (especially when cold) and steep driveways etc, that wear them out quickly.
Here is another pic, this time at Calder Raceway, ready to go on the track.
