+===== Upgrade Clutch Diaphragm Springs - Pressure =====
+Below are a list of upgrade versions. The 'xx% stronger' are claimed values by the respective vendors.
+Energy One suggests that if you are using a diaphragm spring of +25% that you should also upgrade your pressure plate to a billet version because they have had issues with the stock cast pressure plate cracking. ((cjburr at http://xlforum.net/forums/showpost.php?p=666722))
