I called HST a couple times about this, and the explanation I was given was that the hardware in the regular RSR kit is the same as it was for the mk6, but they have since downrated it for the mk7 because the 'torque is delivered in a much more aggressive way' in the mk7, which has resulted in failures for folks making above 380lb/ft in mk7 cars. They didn't recommend it for my EQT Stage 2 tune which they said would be right at or a little over the threshold of what they now say it can handle.
Also, they said that they re-built the Hybrid version early last year because of some longevity issues and some failures at the upper limits of what some people are making with big turbos, etc., and now stand by it up to 550lb/ft, and told me that if I'm not going to the drag strip, etc., that I should be able to get at least 50k miles out of it.
Of course this clutch is new to me, and I never had the regular version, so I'm just passing on what they told me rather than vouching for anything. Clearly some people have been fine with the regular version at pretty decent power levels.
Honestly kind of bullshit. I figured they downrated it for the mk7 because it has a harder torque curve, but 480 is 480.
I don't like that.
