I have seen somebody selling this clutch kit brand new for £700 and was wondering if its worth buying? Has anybody used one of these clutches before or am I best buying the one from Alex on here for a wee bit more?http://www.awesomegti.com/car/vw/golfmk5/loba-sachs-vag-2-0-tfsi-tdi-stage-2-upgrade-clutch-kit-single-mass-flywheel-sw10182
