Logging on to the SPEC website, we see all of the pull down menus that list all of their applications. The SPEC pages for each make, model and year of vehicle also lists exactly which stage clutches are available for that application. Beside each stage and type of clutch is the recommended torque rating of your current mods and then the cost, to find that balance of price to performance that enthusiasts want. Norton added a number of applications, and if your car is new to the market, chances are they have a variety of clutches available already. The 2011 Mustang, 2011 Subaru WRX/STI, VW GTI and the all-new 2011 Scion tC are just a few examples. Norton says they are currently developing a couple of applications for the Nissan Juke turbo and the Chevy Cruze turbo.
