2015-2022 Subaru WRX/STI Master Cylinder by Clutch Masters x WilwoodWhen 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 you want just a little bit of a 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. The other notable upgrade this kit will do for you eliminates the clutch delay valve that is built into the factory master cylinder. The delay valve is a one-way regulating valve that slows the fluid returning from the slave cylinder after you let off the clutch. This delay is especially noticeable in quick 1-2 gear shifts where you get back on the gas before the clutch is fully engaged. By getting rid of the delay valve you can shift quickly and the clutch is immediately engaging. On high-powered cars where you want to still enable a little bit of delay or slip of the clutch to prevent the drivetrain from getting a shock, check out our tuneable Flow Control Valve.
This is a complete plug-and-play kit and includes everything you need to install this system. Will work with OEM slave cylinders.
Kit includes Wilwood Master Cylinder, (.750" Bore) 3an stainless steel line, fittings, hardware, billet aluminum master cylinder adapter, billet aluminum reservoir cap, and billet clevis.

No polarity and super bright.

Quick installation. Turned my halogen lights into led lights. No issues with polarity and no error codes. The license plate light shine much more bright than halogen lights. Amazing upgrade. Great price and highly recommend.

Affordable and hassle-free
Size: 921/912, Color: White
These reverse lights are super bright! The old bulbs left things practically pitch-black for night driving, total game-changer once these went in. Affordable, hassle-free upgrade that makes all the difference.
