I have a full Sachs x-tend kit in mine, not a Sachs Performance kit. It's rated to hold more torque than an OEM clutch but still isn't enough.
Currently the car should be putting down somewhere around 440nm of torque and this brand new clutch got worn out quite a bit in just under a year. If I do a pull all the way to 200, then stop, I can smell the clutch even 5 minutes after, so it's definitely slipping.
I'd probably pick the Sachs Performance kit, rated for 550nm if you want to go K04.

When I had my buddy do the clutch he said he doesn't want to replace it since it's not leaking, even tho I had bought the part. Now it's leaking so there's a chance some of that oil is getting on my clutch, hence why it smells burns after flooring it. Or I could be completely off and it's indeed a clutch that isnt able to put down the power.
