I don't think you get my point, You are again bring the stock issue here, even the performance parts are designed to wear down such as clutches. If the was not the intention then they would have not used wearable parts again, rather used a full mettalic surface with a clamping power so high that it would shatter the flywheell in a single sec. Does not matter if it is aftermarket performance or stock parts they are wearable. The only difference between stock ad aftermarket is that performance parts are designed for a single purpose and with better and expensive materials, which would make your stock part as expensive if used by the OEM. As for an expert, well I know one thing you are not good reader, even with our previous arguments , you wanted to understand what you thought rather then what I wrote. Well about me you can think what you want, expert or not. I do this not as a hobby only but as profession too. By just driving a 4efte, it does not make you a champion on turbos or performance parts research does.
