There are many reasons why you need a replacement clutch. Maybe you have hit a milestone and have gone 150,000 miles and your disc has seen better days. But we all know the truth. We don't buy cars to take on long walks, we buy cars to push them to their breaking point. If you have attempted one too many launches, one too many failed AWD burnouts, or if you have seen one too many Hoonigan videos, then you're in the right department. So why a single disc clutch? There is no rhyme or reason it's just your personal preference. We carry a large variety of ACT single disc clutch kits for those with a full bolt-on STI, or if you want a stock clutch for your Evo, then you might be interested in an Exedy Stage 1 Clutch Kit. You can also choose from ceramic, organic, 6-puck, heavy-duty, and many in between to tailor to your driving style. Keep in mind that all single disc clutch kits come with everything for installation. This includes a new throw out bearing, pilot bearing, as well as an alignment tool for installation. It is never a good idea to try to get a new disc and make it work with the rest of your BBQ'd clutch parts. Do it right the first time with a new single disc clutch kit. And while you're at it, make sure that you resurface your flywheel, and if you can't resurface your original flywheel, then come back and choose the right flywheel for your clutch kit.
