AMS 722.9 Performance Frictions Clutches - Thanks Shardul and UPD!
Just a quick shout out to Shardul @ UPD for getting me these AMS clutches quickly and for a great price. Install in a couple of weeks and I'll report back.
Great stuff, excellent bite compared to stock
Make sure you are changing trans oil after first 500 miles use after new clutches install
There are lots of break in material from new clutches that can block the solenoids

good tip that a lot of people forget..... i forgot for about 1000 extra miles when i did rs4 clutches on my audi b5 s4 and was pretty surprised at excess material in my pan.. luckily didnt cause any problems but who knows if i left it for another 1000 miles
After I just did the clutch upgrade, the dealership said it had a hard time adapting the trans. In Manual mode it shifts perfect, but in Comfort it wants to jump up gear way too fast. Anyone with the AMS clutches have this happen to them?

All of the aftermarket clutches for E63 claim to hold 1,000 foot pounds of torque. I know of a couple of instances where that is not the case in real world. Is there any recourse with these clutches if they start slipping in a month or so?

Well these have been holding about that torque level for a month now in my car, but I can't say they will not glaze over time.
Ultimately transmission tuning is also required for high performance automatics to ensure enough line pressure and clutch to clutch transitional shift pressures are sufficient to keep from slipping clutches and burning them up. This is common in the GM 6l-8l 80/90 platforms, where you have the like of HP tuners allowing you to modify those parameter. I think on the 722.9 platform we are kind of screwed until the SW tuning catches up with HW.
No matter what, making an automatic clutch to clutch type transmission live with more than 1000ft-lbs is always going to be a challenge. No such think as bulletproof in our world.
