I think he’s probably referring to single or dual mass FLYWHEEL not pressure plate, std is a dual mass flywheel setup which can’t be machined to suit a new clutch so u have to buy a new flywheel as well as the clutch they sell kits that come complete with a flywheel and clutch setup, if wanting to upgrade ur clutch then a heavy duty clutch with a single mass flywheel is the way to go and also if ever you need to replace the clutch in future u don’t have to buy another flywheel again as it can be re machined
