what do your clutches feel like compared to other cars?

my 931 clutch has by a good margin the narrowest window of pedal travel where you can slip the clutch..

feels like maybe an inch of travel between where its disengaged and where its engaged..

its not really stiff compared to other cars but its much more like an on/off switch than a dimmer switch if you know what I mean..

I think it may be something aftermarket...

unless this is regular on 924's... and im wondering your opinion on it..

the gf hates it

- N/A 924, effortless. Sorta mushy, not terrible. But OK.
- On the '79 N/A 924 I drove, the cable was a bit old and had a few split spots I had to consistently lube or it would get harder to engage. That was because it was dirty, nothing else. Aside from that, engaged like a mushy N/A 924 that was stock.
- Porsche 944 N/A. Mushy, not impressive. Replaced with aftermarket clutch, felt more direct, still effortless due to hydraulic.
- 931, more direct. Reminds me somewhat of the 944 N/A but mine certainly grabs harder. Uncertain if the clutch is stock or not.
- 951, the one I drove had an aftermarket clutch and grabbed hard. Easy engagement but grabby and very very direct. Not sure what a stock one feels like.
- 914, was adjusted almost too much on the side of almost no travel. Engaged quickly, and fairly quick since it was such a small and light car. Very little effort, but good feedback.
- 911, had it adjusted somewhere in the middle. Engaged well, good feedback, felt nice, grabbed decently and didn't chatter hardcore when slipping it lightly.

Not normal.
Your car has been sitting for an extended period so you may have air in the system, bad fluid, leaking m/c or slave cylinder. You can try new fluid and bleeding. You should also check the wear on the clutch, engagement changes with wear. There is also a manual adjustment of the m/c rod to the pedal someone may have played with.

Air can't get in the system without a leak. Water can & will be absorbed into the fluid though.
Its likely the m/c and/or the slave are shot. They can leak internally (can't build proper pressure) or externally. Change them both, cheaper than a tow that you will probably need if you don't.

The clutch will work even when down to the rivets. The pedal travel is related to the clutch disc thickness. There is a easy measurement procedure to check disc thickness.
