I just recently pulled out my clutch because its starting to slip. I read here at TT that if you rough up the friction plates (sand them) a little you can get some more life out of them, i did that, and its still slipping. (plates are still all in spec) so my next option is to get some new springs, i want to get some high quality ones that wont wear out, but i dont want to pay $60 some odd bucks for a couple of springs! so my question is, are stock springs any good? and will they last for a conciderable ammount of time?
