Clutch Masters FX500 Stage 5 Clutch Kit 6-Puck Subaru STI 2004-2021 | 15017-HRB6

Part #: 15017-HRB6. The FX500 clutch kits are a game-changer, offering a holding capacity that's 200 - 400% greater than stock. They use a solid hub for super - fast engagement. This clutch isn't suitable for Subaru STIs used on the streets. It features an unsprung style disc that gives an extremely hard and quick clutch engagement with zero slippage. Ideal for fully - raced or drag - modified STIs with upgraded gear sets only. Driving this kit on the street would be a real challenge, so don't buy it if you plan to use it for daily driving. The 6 - puck kit dissipates heat better than the 4 - puck one, but the 4 - puck can handle a bit more power. Included in the kit are a pressure plate, a clutch disc, a throw - out bearing, a pilot bearing or bushing (when applicable), and an alignment tool.

Using this clutch kit is straightforward but keep in mind it's designed for high - performance racing and not daily street use. First, make sure your Subaru STI has upgraded gear sets as this kit is only suitable for such modified vehicles. When installing, use the included alignment tool to ensure everything is in place correctly. During use, you'll notice a very quick and hard clutch engagement, which is normal for this type of clutch. As for maintenance, check the clutch components regularly for wear and tear, especially the clutch disc and pressure plate. Also, keep an eye on the throw - out bearing and pilot bearing or bushing. If you notice any unusual noises or a decrease in performance, it might be time to inspect the parts closely. Remember, this kit isn't meant for regular street driving, so avoid using it in daily commutes to prevent premature wear.
