Default uprated 850R clutch???

I have had fitted for a while now the TTV flywheel with standard Sachs 850R clutch kit. i heard stories from Smithy that he melted one on the rollers when his car was 300bhp and was a bit dubious as i was aiming for that kind of power myself.....
fast forward a couple of years and i have just had a bigger turbo, injectors, cam, MAF, mapping etc and definitely making slightly over 300bhp and sure enough within a day i can feel clutch slip in 1st and second gear...
Has anyone uprated their clutch? can anyone recommend an uprated 850R clutch that will work. i don't want a paddle clutch if i can help it at all. a slightly uprated one should do the trick as i do not want to increase the power any more yet...
Any help greatly appreciated

The 940 I've got in the garage has the TTV flywheel with Sachs 707 pressure plate and a paddle friction plate. It was pretty heavy and grabby I must say - I certainly I wouldn't like to drive it in traffic for any length of time.

Maybe if you combined the heavier pressure plate with a more conventional friction plate it would take away some of the grabby-ness? It would still leave you with a heavy clutch though.

Let me know if you need to rid yourself of the turbo, maf etc. Detuning would sort your clutch slip 😁. I was pestering Martin for the set up but you had already paid for it 😢.

LOL. absolutely no chance whatsoever!!! The power is awesome...exactly what i had hoped for!!! i would never let a trivial matter such as a slipping clutch hamper the fun!! Martin is a legend and has done an awesome job of mapping the car. along with his brother who did a great job of actually fitting the hardware!!
i realise i was very lucky to buy that setup and believe me i sacrificed a lot at the time...my ex girlfriend still gives me earache about her bike i sold to buy it all!!.....

i'd look at a carbon kevlar clutch, you're right to avoid paddle.
can't remember top of my head who we've used before to reline material, but can be done, just start with a decent plate.
