Heavy clutch,my knees shot, how can i make it lighter, i don't have an extre £40k for PDK,
My 997 Gt3 is now killing my knee and after 30 mins I have to stop, I don't have £40k for a PDK, any tips or sensible advice besides selling her how I can make the clutch more knee friendly.
Thanks Jez

Do you need s replacement clutch? Mine is not too bad. 
 
Would a knee bandage/strapping help

I agree with Robin. Sounds like you need a replacement clutch. I had the same experience as you when I first got my one, and after a change is a lot better.
 
I do have to note that the 911s tend to be heavier compared to other makes. So if it still feels heavy after a change, then time to build up the legs in the gym.

As above - the clutch material when it wears away coats the inside of the bell housing and can cause additional friction in the mechanism (pressure plate can also develop wear characteristics)
 
Are any fellow members / friends willing to let you try theirs? (fingers crossed they have a light clutch!) ... this would avoid shelling out to see if it was just needing a replacement.
 
Other things you might read about which you might consider to be ‘low-cost shots in the dark’ ...
clutch fluid bleed/change ...
replacing some of the clutch hydraulic parts...
There is a spring on the clutch pedal too.  
 
... All unlikely to be responsible, but you never know!

Sell it and buy a 968 tip coupe - and trouser the difference in price!!When we were in Northern Spain a couple of years ago, if I'd been driving a manual car my left leg would have been toast rather rapidly - but I was in a 968 tip cab, left leg redundant!! Plus a 968 coupe gives you luggage space that those rear engined things struggle for!!

Larger master cylinder or smaller slave cylinder or combination of both will alter the amount of pedal effort needed. But I agree the first step is to ensure the clutch plates are good and the release system is working correctly.

Did you fix the heavy clutch issue?  I am having the same with my 991 C2.  40k miles on the clock, original clutch, so maybe I should be looking to replace the clutch, slave cylinder and pedal spring.  Plus anything else involved in the clutch operation.

My 997 C2 has a heavy clutch with just over 40k in 11 years.  It was noticeable the day I test drove it two years ago and it seems to be a characteristic anyway, but maybe a little heavier than it might be.  I changed the clutch fluid in January as a long shot but it made no odds so the only remaining options seem to be pressure plate and/or clutch itself.  It hasn't got any worse in two years so I am not worrying at this stage as I manage ok and in any event the engine has so much torque that I don't have to constantly fish around with gears when trundling about.  That said, a long trip in stop/start traffic would make a difference.  Manual gear boxes may be considered more "fun" and "engaging" but there is no way you can match the instantaneous performance of a PDK (had one one my 987), so it comes down to choice and budget...I am sticking with my manual.
