I cant figure out how companies like wisco and spi and hot rods can still be around. stuff like mufflers the factory makes them to work best with there motor right? how can slp /bmp /diamond light make a living . u have places like team wow I was always under the assumption that the oem know what clutches were best for there sleds. it was a shocker when poo went to them then cat man crazy stuff there testing must not have been all they thought it was . belts I assume the compounds have to be tested over and over in the factory but I like my dayco better hope if I blow my motor they don't blame the belt.
don't these aftermarket suppliers know they are wasting time because the oem always knows best and sells the best . u know how well they treat us they would never have us pay 14k to test for them
. all stand up corporations all in it for us before there bottom line
