ECS Tuning's Polyurethane Transmission Mounts are designed to address the vital role of transmission mounts in your vehicle's suspension. The factory mounts are notorious for failures that can result in over-revving, mis-shifts, and in extreme cases, potential chassis damage. Our polyurethane mounts provide a robust solution, engineered for both street and track applications, guaranteeing enhanced performance while eliminating concerns about torn mounts.

Polyurethane stands out with its exceptional toughness, durability, and impressive wear resistance compared to rubber. It also exhibits resistance to water, oil, and grease while retaining its original shape even when subjected to significant compression. By reducing deflection, polyurethane facilitates effective power transfer. While there may be a slight increase in NVH (Noise, Vibration, Harshness), the benefits far outweigh this minor compromise in ride comfort. With a polyurethane durometer of 70A, our street mounts are versatile, offering both daily driving comfort and track durability. For more track-oriented enthusiasts, we provide stiffer mounts with an 80A durometer rating.

For a hassle-free installation, we supply a comprehensive DIY guide. ECS Tuning ensures that you are fully supported from start to finish.

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:
1984-1991 E30 BMW 318i 318is 318ic 325e 325es 325i 325ic 325is 325ix M3

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.

Convert your open differential to a locked differential without the costly expense of an LSD replacement.

Get your car ready for aggressive track driving or drifting without purchasing or replacing your differential. The weld-in plates strengthen your diff and allow both wheels to engage simultaneously giving you a more predictable and capable track car.

An open differential allows the wheels to spin at different speeds and sends power to the wheel with the least amount of traction. This may be a good feature for your regular everyday driver but limits you on the track. The weld-in plates simulate a driving experience similar to a limited-slip differential allowing you to put power to both wheels in a low traction area or initiate drifts.

Features and benefits:

Added strength to your differential gears
Converts from open differential
Fabricated to fit in the spider gears for an easier weld and increased confidence
Made from 7 gauge mild steel, formed to fit
