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.

Some modifications to your vehicle may not produce power to create gains in the overall performance of your driving. When you add a "Po' Boy" clutch stop to your BMW the performance gain is directly felt in the driving experience.

The ECS clutch stop allows the driver to fine tune the position of the clutch pedal to closely match the engagement point for precise, quicker shifting. The adjustment range found in this product can be set to the stock engagement point or can be adjusted to follow the wear of the clutch.  Meaning your new experience will never change all the way to the end of the clutch life and can be reset to enjoy the next clutch.

Note: This modification might require some slight modification to the clutch switch mounting bracket, which can be bent slightly by hand.

Requires shorter flywheel bolts - 8x (P# 11227805885) - T#12322

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. This flywheel requires the E34 M5 sprung hub clutch 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

Ensure the longevity of your BMW's drivetrain with ECS Tuning's Magnetic Plugs. These plugs are meticulously engineered in-house to provide a perfect fit and feature a permanent magnet attached to the plug body. The magnet effectively attracts and captures tiny abrasive and ferrous metal particles, preventing their circulation through lubrication systems. Metal particles can accumulate due to various conditions such as normal wear, machining operations, casting flaws, and stress usage, leading to excessive wear of vital components. ECS Tuning's Magnetic Plugs help alleviate this concern by trapping these particles, thus safeguarding the internal components of your drivetrain. With a convenient 17mm hex head design, these plugs eliminate the need for special tools required for OEM plugs.

Key Benefits:

• Removes abrasive metal particles from drivetrain fluid
• Prevents excessive wear to internal components
• Meticulously engineered for a perfect fit
• Features a permanent magnet for efficient particle capture
• Convenient 17mm hex head design for easy installation

BMW E46 Z4 Rear Polyurethane Differential Bushing Performance is the ultimate upgrade for enhancing the connection between your BMW's chassis and differential. Designed by Turner Motorsport, this performance bushing replaces the soft factory rubber with durable polyurethane, offering superior control and response. By minimizing vibrations and reducing deflection, this bushing ensures a more direct and responsive driving experience, making it a must-have for any performance-oriented BMW E46 or Z4 owner.

• Enhanced Performance: Replaces the soft factory rubber with durable polyurethane for improved driveline response.
• Reduced Vibrations: Minimizes vibrations between the chassis and differential, providing a more connected driving experience.
• Increased Durability: Made from high-quality polyurethane, offering long-lasting performance under demanding conditions.
• Improved Control: Reduces deflection, ensuring a more precise and responsive handling experience.

Shifter slop is a common complaint among all BMW models. Some of that play comes from the bushings where the shifter carrier mounts to the transmission. The original rubber carrier bushings don't last very long and when they get too soft the shifter flops around. These Teflon bushings are not as stiff as Delrin so they won't transmit as much vibration and buzz in the shifter. Yet Teflon will last much longer than the factory rubber, giving you precise shifting for many years.

Note: this is only one part of the shift linkage and there may be other components that need replacing to improve shifting feel.

We advise getting a replacement bushing carrier pin as well. If the original rubber bushings are worn the pin will have wear too and you will still have slop in the shifter, even with the new bushings.

These are the ROUND shifter carrier bushings (some BMW models have oval bushings).

This item fits the following BMWs:
6/1986-1992 E30 BMW 318i 318is 325e 325es 325i 325is 325ic M3
1992-1999 E36 BMW 318i 318is 318ic 323is 323ic 325i 325is 325ic

The ZF 320z S5D is a common swap choice among BMW enthusiasts due to its reliable and robust nature. Unfortunately, it does have a weakness. The detent pins and springs that live inside of the transmission are known to wear down over time, often causing the shift lever to lean towards the 5th gear position when in neutral.

This full-service kit consists of everything you need to replace the failing detents in your ZF transmission. The kit contains only Genuine ZF components, all of which are sure to provide you with smooth shifting and operation for years to come.

This kit includes the following items:
