I'm with Crooster. I wasn't raised to shift with the engine rev'd. We needed our farm equipment to last a LONG time. I treat my Boxster the same way.

Porsche did make farm equipment.

WOW did this thread ever go sideways.
Do you get grind/issues shifting at lower RPMs?
Where is your clutch pedal engaging (Bottom-Floor, middle, top) should be middle-ish
You can do as mentioned Fluid changes, front motor mount. This would not be a waste of time as mounts typically need replacing anyways and fluid changes (trans & clutch) are just good maintenance.
There are also (2) trans mounts. I believe they are filled with fluid so when they go bad they tend to leak

I'm not familiar with the shift cables but could that contribute any way?

I don't have any shift problems in any other gears or at lower RPMs at all. Silky smooth all other times.

Clutch engages low to middle

I'm wondering if it is just a bad 3rd gear synchro, but the car only has 39K miles on it and was babied so I'd be really surprised if this went bad already.

Have you tried double clutching Alfa Romeo style?

Same trouble here with 3rd, but not all times fortunately... Mine is 95000km driven, near mintcondition too. I going to try changing transmission oils first..
