Well, I haven't modified my engine and if I do in the future I don't plan on moding it to much. So right now I'm basically just looking for a replacement clutch that is relatively cheap and will last me quite a while, i'm willing to pay a bit more if it will last me longer then the cheapest clutch out there. But as it is right now i'm looking at the 80 dollar clutches and comparing it to the 280 clutches, i'd rather pay the 80 bucks if the price difference is that much, and the performance difference isn't there..
