BMW has long suffered issues with rear shock mount blowout on M3 and non-M 3 Series models dating back to 1984 with the E30 chassis. Little changed over the following two decades, and E36, E46, and Z3/Z4 models are also prone to this style of failure. After striking a pothole or another seemingly innocuous obstacle, a clunking from the rear emerges and handling becomes sloppy. Your shocks have blown through their mounts. Enter the Ultimate Performance Rear Shock Mount Kit from ECS Tuning. Not only does their industry-first design alleviate the blowout problem once and for all, but allows rear dampers to fully articulate, for the best possible damper performance and longevity. They accomplish this with no noticeable increase in noise, vibration, or harshness (NVH) thanks to their unique rebuildable polyurethane isolation. The poly bushings not only keep NVH to a minimum, but they also reduce impact loading on the bearing, improving bearing life over full solid mounted monoball designs. To further improve bearing life and longevity, this design incorporates a lower dust seal to keep road debris, grit, and other contaminants out of the bearing. These are one of the best rear shock mounts available, and the last you will ever need. Features: Maintenance-free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation Lower dust seal for improved bearing life 80A polyurethane isolation bushings for NVH control and improved bearing life Accommodates 10mm* Fully constrained shaft mount makes blowouts impossible Hard anodized 6061-T6 construction Class 10 black zinc plated studs New OEM lock nuts included Fully rebuildable design *For use with factory-style 10mm damper shafts. If you have factory-style mounts presently, you have 10mm damper shafts. *During installation a 17ft-lb torque spec is required to avoid damage to the mounts.

ECS Exact-Fit stainless reinforced brake lines ensure consistent and reliable stopping power - ECS's stainless steel lines help maintain consistent brake pressure, while capitalizing on the inherent benefits of stainless steel. If you are already planning on replacing your factory lines due to your vehicle's age, ECS's stainless steel brake lines are a great solution. Factory rubber lines expand under heavy braking, even when new. This causes sloppy pedal feel and overall poor performance. ECS reinforces their exact fit lines with braided stainless steel mesh, creating expansion resistance - this enhances pedal feel and improves performance. Their red polymer coating provides protection from the elements and abrasion that commonly affect brake lines. ECS Exact-Fit stainless lines are manufactured to comply with DOT (U.S. Department of Transportation) FMVSS 106 standards. All lines are made on dedicated, DOT-compliant brake equipment, with every line being tested to 3000 psi prior to shipment.

Want a race-spec rear shock mount but with the comfort of a factory bushing? This ECS rear shock mount combines the precision and articulation of a spherical bearing with the isolation of urethane bushings. The stainless monoball bearing is lined with PTFE lubricant and suspended in 80A urethane and housed in a hard anodized 6061-T6 aluminum mount. The spherical bearing is a better design than most rear shock mounts because it allows the shock to move and tilt without side-loading the shock shaft (which leads to premature failure of the shock). Most Genuine BMW and aftermarket shock mounts are not designed for shock angles and the stress that track or performance driving will put on the shock shaft. The ECS shock mount is properly designed to handle these loads. The internal bearing is also replaceable - it will be years before you have to replace the entire mount. The ECS mount is fully encapsulated to prevent the common shock mount failure of the stock mount design.

ECS RSM features:

  • Maintenance free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation
  • 80A polyurethane isolation bushings for NVH control
  • Accommodates 10mm, 12mm, or 14mm damper shafts
  • Fully constrained shaft mount makes RSM blow out impossible
  • Hard anodized 6061-T6 construction
  • Fully rebuildable design

* - the RSM comes with the BMW standard 10mm shock shaft bushings. 12mm is used on some performance shocks and 14mm is used on some true motorsport rear shocks.

The factory center support carrier features an internal bushing constructed from soft, pliable rubber. While this provides a smooth and quiet ride for standard driving, it falls short in performance-oriented applications where durability and precision are critical. During acceleration, shifting, and under load, the rubber bushing's inherent flexibility allows for excessive driveshaft movement. Over time, repeated stress and wear on the rubber will cause bushing failure, risking poor driveshaft alignment and efficiency. In extreme cases, this failure will cause a constant rotational "clunking" noise, a clear indicator of impending failure.

The ECS Tuning Center Support Bearing Brace is designed to enhance the performance and longevity of your drivetrain. To improve upon the factory design, and to create a performance alternative, our engineers started by designing a set of exact-fit, split low durometer rubber bushings that clamp around your existing driveshaft bearing. Crafted from 30A durometer rubber, our material choice effectively eliminates bushing deflection without causing an increase in noise, vibration, and harshness. By eliminating deflection, this design ensures a longer lifespan than the stock center support bearing, making it a great investment for enthusiasts looking to maintain their aging BMW chassis.

The rubber bushings are encased in a high-strength 6061-T6 billet aluminum bracket, engineered for both durability and performance. Like the bushings, the bracket features a split design, allowing for seamless installation without the need to remove the entire driveshaft assembly, saving time and effort during maintenance or upgrades. To ensure reliable clamping and secure fastening, the bracket is equipped with two corrosion-resistant stainless steel socket head screws. This design simplifies bushing replacement and provides a dependable and sturdy hold, even under high torque and stress conditions.

FEATURES

Exact-fit bushings are made from 30A durometer rubber to eliminate bushing deflection while maintaining a smooth, quiet ride.
Solid fill rubber construction offers a longer lifespan than flimsy factory rubber, ideal for enthusiasts looking to eliminate future CSB-related problems.
Bushings are encased in a 6061-T6 billet aluminum bracket for enhanced durability and improved performance.
Both the bushings and the bracket feature a two-piece split design, allowing for seamless installation without driveshaft removal.
Designed with performance in mind, this upgrade eliminates excessive driveshaft movement for improved alignment and efficiency.

Enhance your wheel changing experience with a stud conversion kit tailored for your BMW, designed to streamline and expedite the process. The kit comprises:

  • Conical Seat Lug Nuts (10)
  • 55mm Wheel Studs (10)

This conversion provides permanent wheel hangers, minimizing time and hassle. Simply screw in the provided studs for quick and easy installation.

Why Choose Wheel Studs Over Wheel Bolts?

  • Added Confidence: Some racing regulations require wheel studs for improved wheel-to-hub contact, ensuring additional security.
  • Versatility for Spacers: Wheel studs accommodate various spacer widths in one application, eliminating the need for custom bolt lengths with different spacer sizes.
  • Ease of Installation: Wheel studs simplify the wheel installation process while the nuts secure the wheels in place.
  • Reduced Wear: Wheel studs in the hub reduce wear on wheel hubs, compared to frequently removing and installing wheel bolts, enhancing longevity.
  • Quick Tire Changes: Wheel studs facilitate swift and effortless tire changes or removal.

*Note: Apply thread-locking compound during installation and torque studs to 15Nm. These studs support spacers up to 10mm in size.*
