Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

This brass clutch pivot pin is an upgrade over the stock plastic pivot pin. The brass pin will last a lot longer than the plastic piece and may save you time and hassle later on. The original plastic pivot pin is known to fall out, snap, or just wear out over time. At the least you get a very annoying squeak every time you depress the clutch. In a worse case scenario, the clutch fork won't be able to push on the throw-out bearing and your clutch will be useless. The only time to replace the clutch pivot pin is when the transmission is removed, so this brass upgrade can be installed during clutch replacements or a rear main seal service.

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.
