What type of performance/feel are you looking for? Various types of clutch assemblies provide very different performance and function.

 

Ask yourself this...are you willing to live with "gear lash" noise from the trans or not? When people say clutch, it's usually synonymous with replacing the flywheel. If you go with a lightened single mass flywheel, you will get loud gear lash noise in the trans when applying throttle(torque) at low RPM (<1500).

If you stick with the OEM Dual Mass Flywheel, then go with whatever clutch meets your torque needs and driving style. If you simply want something reliable for everyday use, JWT's HD clutch is a popular choice. But there's so many to choose from. Do some looking around on the forums, plenty of people have reviewed different clutch and flywheel combos.

If you're going aftermarket, use a real clutch brand's setup. Not (enter a popular Z parts company). ACT makes great products.
