From what I am gathering, you aren't complaining about slippage or a performance problem but more reverberation and chatter felt literally from the clutch pedal to your foot? Correct? If it is mild, meaning that the car isn't shaking or bucking then I would say that what you are experiencing is normal, but for alot of aftermarket clutches. However, the feedback that you and I speak of could be of complete difference. What you may be feeling, may not be exactly what I picture in my mind. So here is the jist of it. Every time that I replace a clutch, be it BMW, Ford, Chevy, stock, aftermarket or racing, I either resurface or replace the flywheel. On every BMW clutch that I ever wrote an estimate for, I inlcuded a new flywheel. The reason being exactly what I hear you describing as "feedback", most likely attributed to imperfections, cracks, material build up etc on the surface. Just the same as brake pads and discs. If you are replacing/renewing the surface of the pressure plate then why would you not do the same for the flywheel? It is engineered with the same gripping duties as the pressure plate but for different reasons. Also, aftermarket clutch kits are not always equal in quality to OEM; and by this I mean the balancing and sometimes materials are not quite up to OEM quality. So throw a little unbalanced parts on top of a "dirty" flywheel and you will always get "feedback". All in All, if you want to replicate the way it was from the factory, you have to put all the parts in like they were from the factory, *brand new*. I wouldn't necessarily worry about it unless you start noticing a lack of performance or slipping. But for future reference, either resurface or better yet replace the flywheel (if affordable of course). If you are experiencing more than just a little reverberation in the "feel of the pedal", then let me know. We might need to examine a little more; there could be other issues with yours. Sorry for the verbal diarrhea. Hope I helped!
