The ECS Billet Master Cylinder Fitting is the ultimate solution for a notorious failure point in BMW E30 clutch systems. This critical fitting, located at the end of the master cylinder reservoir hose, is responsible for delivering hydraulic fluid to the clutch master cylinder inlet. Unfortunately, the OEM plastic fitting is prone to degradation after prolonged exposure to brake fluid, often leading to total hydraulic pressure loss and brake fluid leaks inside your vehicle.

ECS has addressed this issue by engineering a robust and long-lasting alternative. Crafted from 6061 billet aluminum and finished with black hard-coat anodizing for superior corrosion resistance, this precision-machined fitting replaces the fragile plastic original, ensuring leak-free performance for the lifetime of your vehicle. Upgrade to our Billet Master Cylinder Fitting during your next clutch master cylinder service and enjoy peace of mind knowing your BMW is equipped with a durable, high-quality solution.

Features & Benefits:

Made from 6061 billet aluminum for a permanent, reliable upgrade over the factory plastic fitting. Black hard-coat anodized finish ensures long-lasting protection against the elements. Precision-machined barbs match OEM dimensions for a leak-free seal with Genuine and aftermarket master cylinders. Designed for a secure fit within the factory grommet location. Prevents brake fluid leaks and loss of clutch hydraulic pressure caused by plastic fitting failure. Upgrade your BMW and bulletproof your master cylinder with the ECS Billet Aluminum Master Cylinder Fitting. Ensure clutch hydraulic system reliability and enjoy peace of mind knowing your failure-prone plastic master cylinder fitting has been addressed.

This braided stainless steel line replaces the stock hydraulic hose connecting your clutch slave cylinder to the clutch master cylinder. There are several deficiences with rubber, especially as it ages - when new the rubber expands and swells under pressure and the pedal can feel spongy. As rubber ages and is exposed to extreme temperatures the rubber can harden and even shrink (common on brake hoses), which results in a stiff pedal. Rubber clutch lines do not stand up to the stresses of hard use. ECS Exact-Fit stainless reinforced clutch lines provide more confident and dependable shifting by maintaining consistent line pressure, long lasting corrosion resistance, and increased protection from failure. These lines are reinforced with braided stainless steel mesh, affording superior expansion resistance. This resistance to expansion creates a firmer pedal, and a more direct clutch pedal feel. The signature red polymer coating provides additional protection from the elements and abrasion.

This particular stainless steel clutch line fits the following BMWs:
2004-2010 E60/E61 5 Series 
2004-2010 E63/E64 6 Series (manual transmission only, no SMG)
2011-20116 F07/F10 5 Series 
2011-2016 F06/F12/F13 6 Series

Eliminate the factory clutch delay valve and enjoy faster, more precise clutch engagement with the ECS Clutch Delay Valve (CDV) Removal Tool Kit. Designed for F and G-Chassis manual BMWs, this kit makes removing the hydraulic restrictor safe, simple, and reliable, no slave cylinder removal required.

Most modern BMWs come from the factory with a plastic slave cylinder featuring a CDV, intended to smooth engagement and reduce driveline shock for less experienced drivers. In practice, this restrictor can dull pedal feedback, slow shifts, and increase clutch wear. Removing it restores the sharp, direct clutch feel that BMW enthusiasts expect.

Key Benefits:

Faster, more predictable clutch engagement
Sharper pedal response and connected driving feel
No need to remove the slave cylinder
Tool Design:

Machined from durable 304 stainless steel
Includes precision removal and insertion tools
Knurled grip for easy handling
Built-in depth and angle control protects internal surfaces and ensures proper grommet alignment
Removal and Installation:

Disconnect the Clutch Line
Remove the clutch line from the slave cylinder to access the factory clutch delay valve.
Remove the Restrictor Plate
Thread the removal tool into the center of the small grommet. Once engaged, carefully pull the tool to remove the grommet and restrictor plate. The small rubber sealing O-ring will come out along with the plate.
Reinstall the O-Ring
Place the rubber O-ring onto the installation tool. Insert the tool into the slave cylinder to properly seat the O-ring in its original position.
Reconnect and Bleed the Clutch
Reattach the clutch line, add fluid, and bleed the system according to your manufacturer’s instructions.
Enjoy Enhanced Clutch Feel
With the delay valve removed, your clutch now engages faster and more predictably, giving your manual transmission the sharp, connected feel it was designed for.

Lightweight flywheel and upgraded clutch kit for improved throttle response, acceleration, and clutch feel - the perfect setup for daily-driven vehicles with up to 400 Ft/lbs of torque.

This performance clutch and flywheel kit utilizes an upgraded ECS E34 M5 clutch kit with their in-house engineered flywheel to fit all M5x and S5x motors with a 5-speed transmission. By eliminating the dual-mass flywheel and replacing it with a single-mass you are able to eliminate the slack and extra weight of the flywheel for a quicker throttle response and acceleration. Their upgraded clutch kit utilizes all the best features of the original M5 clutch with an upgraded pressure plate and clutch disc, with the new clutch you have a better, more engaged clutch pedal feel, engagement, and longevity.

Whether you're replacing a worn-out clutch or upgrading for increased power handling, this E34 M5 clutch and flywheel kit offers a reliable solution for enhanced pedal feel, power capacity, and overall driving satisfaction.

Paired with a modified geometry flywheel, the E34 M5 style clutch is ideally suited for most E36, E46, and others using the same powertrain. It checks all the boxes for essential clutch replacement features. While some aftermarket options may address slipping issues and worn-out clutches, they often sacrifice pedal feel, providing little to no resistance. A soft clutch not only kills the driving experience of your BMW but also reduces confidence when pushing the car to its limits.

On the contrary, you might be in the market for an upgraded clutch to handle your modified engine/forced induction builds. You go from an OE or aftermarket clutch option that has a lackluster and soft pedal feel to the complete opposite side of the spectrum, a very stiff clutch that grabs like an on-and-off switch making the clutch a pain almost undrivable on the street resulting in your favorite car turning into your least favorite car to drive.

The E34 M5 clutch and flywheel kit balances performance with practicality, ensuring a satisfying driving experience whether you're maintaining your BMW or preparing it for increased power demands.

Lightweight flywheels have proven themselves to be a worthwhile performance enhancement. But with the quicker throttle response and horsepower improvement comes one serious drawback: flywheel chatter. Without the dual-mass flywheel's rubber isolators, a lightweight aluminum flywheel has more rattle than stock. ECS has designed this flywheel using chrom-moly steel and it weighs almost ten pounds less than the stock DMF but not as extreme as full aluminum flywheels. The steel helps dampen vibration and noise so you get near-factory refinement and most of the benefits of a lightweight flywheel: quicker throttle response, better reliability, and more power to the wheels. Zero-balanced and SFI 1.1 certified (material and design has been independently burst tested to ensure quality and safety). This flywheel requires the E34 M5 sprung hub clutch kit. Choose below from the flywheel only or a complete kit.

Modern flywheels are built with additional components that are designed to dampen and minimize vibrations from the engine and transmission. Weight has increased and reliability has decreased. With additional weight more energy is required for it to move. A lightweight flywheel does away with the dual mass design and its additional mass so more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance. And with a single-mass flywheel the unreliable DMF design is eliminated.

Stock flywheel weight - 25.0lbs
ECS flywheel weight = 16.55lbs
