Let's face it, when Honda set out to engineer the 10th Gen Type R, they didn't hold back. However, when upgrading your clutch, don't overlook upgrading your clutch master cylinder as well. Typically the OEM master cylinder will work just fine, but sometimes that master cylinder is getting old and tired and possibly might be leaking. Or maybe your want just a little bit more crisper pedal feel when operating your clutch. Upgrading to the Clutch Masters X Wilwood Clutch Master Cylinder will make sure your clutch hydraulic system is up to snuff and able to handle more aggressive driving. This is a complete plug and play kit and includes everything you need to install this system. Will work with OEM slave cylinders. Alternatively, you can save some money and upgrade your entire hydraulic system by adding on one of our internal hydraulic release bearings that will eliminate your stock slave cylinder and give you a complete performance hydraulic clutch system. Kit includes Wilwood Master Cylinder, (.750" Bore) 3an stainless steel line (two piece line should you want to add one of our Flow Control Valves now or in the future), fittings, hardware, billet aluminum master cylinder adapter, billet aluminum reservoir cap, and billet clevis.
