Unsure of what size spacer will work best for you? This professional kit includes 1mm, 2.5mm, 5mm, 10mm, and 15mm spacers with wheel studs and nuts for you play with. These are not the same spacers that we sell and they cannot be used to drive on. But with the studs installed the car can be lowered to the ground and rolled to check for clearances. These test fit spacers are drilled to fit the standard BMW 5x120 bolt pattern as well as 4-lug 4x100 (and VW/Audi bolt patterns too). You can stack spacers to achieve the perfect clearance. When you're ready call us to order the spacers you need (we make 3mm, 5mm, 7.5mm, 10mm, 12.5mm, 15mm, 17.5mm, 20mm, 25mm, and 30mm spacer thicknesses).

This kit is for purchase only. It's perfect for shops or racecars where changing wheels or brakes is common. We also have kits that are available for rent.

These spacers are not for driving on. They lack the hubcentric lip that BMW wheels are designed to work with. Driving on studs alone will lead to a failure.

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’s are known to have failure prone front thrust arm bushings.  The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change.  This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience.  Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure. 

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!  Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).  We wanted to offer E31, E32, E34, E38, E39, E53, E60, E63, E64, and E83 owners similar levels of handling precision and control for the track and street. 

The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise.  We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting.  The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment.  What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.

Features:

Bearing housing

• Precision CNC machined from 6061-T6 blue anodized aluminum
• Knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands.
• CNC machined 304ss ball joint sleeve inserts, providing a precision fit between the ball joint and the subframe. 

Bearing
