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 goes back to those we designed and used in our IMSA E90 328i and E92 M3 race cars (GS class Champions in 2011). We wanted to offer as many BMW owners possible a similar level of handling, precision, and control for the track and street.

Utilizing 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.

We offer these control arms with the monoball bearings pre-installed for your convenience. Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms.

Control Arm Bearing

• CNC machined corrosion resistant 304 Stainless steel shell, bolt sleeves, & snap rings
• Sealed spherical ball joint for long service life & maintained OE fitment
• Suspension pre-load is no longer required when torquing the control arm hardware

Thrust Arm Bearing:

• OEM BMW sealed, greased ball joint for exceptional durability and service life, even in the most severe operating conditions
• 6061-T6 anodized housing for excellent corrosion resistance
• Proprietary Turner designed knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands
• CNC machined 304ss, providing a precision fit between the ball joint and the subframe

Benefits of Both:​

• Nearly instantaneous, crisp steering and braking response.
• Maintenance free, long lasting performance.
• Improved road feel without undesirable NVH.

Fits the following BMW models

BMW F10 528i, 535i, 550i

BMW F12/F13 640i, 650i

Fine-tuning your coilover damping shouldn’t mean stripping out your rear seats or interior panels. On many applications, rear shock adjusters are hidden behind carpet, trim, or seatbacks, making quick adjustments a hassle.

The ECS Rear Damping Extension Kit solves that problem with a clean and functional solution. These flexible extensions relocate the adjustment knobs to an easily accessible point above the rear shock towers, letting you dial in your suspension from inside the cabin, no disassembly required.

Installation is straightforward: simply drill a small access hole in your interior trim and route the extension cables through. The adjustment knobs can be removed to allow the line to pass through smaller openings, minimizing cutting. For proper installation, be sure to fully loosen the set screw, insert the cable, then securely tighten it using the provided Allen key.

Kit Includes:

(2) Rear damping adjuster extension cables

Installation hardware and Allen key

A smart upgrade for track cars, daily drivers, or anyone who values easy access to suspension tuning, without compromising interior fit and finish.

Dinan Performance Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW springs are carefully engineered to work within your car's suspension travel and to improve suspension geometry. Spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap.

Dinan spring specs -

• F: -1/2" (12mm)
  
• R: -1/2" (12mm)

Fitment note: When used with stock shocks the Dinan Ride Quality Kit is strongly recommended. The Kit consists of shorter and stiffer bump stops and spring perches that work better with the lowered ride height of these springs. While not explicitly required, less than favorable ride quality and handling may result without them.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The springs are worth 2 points towards your Dinan badge (Ride Quality Kit is worth 1 point).

This item fits the following BMWs:
2011+ F10 BMW 550i 550xi

Essential for multiple points in the rear suspension, this hardware should be replaced to guarantee a durable and reliable repair. Don’t overlook the importance of fresh components for optimal performance!

Correct toe settings contribute to both stable steering and even tire wear. The SPC Performance wheel toe bar tool is designed to prevent vehicle drifting and ensure uniform tire wear. It includes a steel bar equipped with sliding adjusters and pointers to accurately assess the vehicle's toe alignment.

For wider wheel bases use T#386442!

When dismantling a suspension strut sometimes the securing nut can be difficult to access and the central strut itself needs to be held still while the nut is undone. This new Shock Absorber Tool Kit is designed to overcome these problems and make the job quick and easy.

The go-through design of the sockets and ratchet design allows the strut lock extensions to go right through the middle of the ratchet and socket. Five different strut lock extensions are included, to fit a variety of applications. Seven go-through deep sockets (16, 17, 18, 19, 21, 22 and 24mm) are included, plus a sliding T-bar.

Once the spring is compressed and the top plate is free, simply choose the correct strut lock extension and socket. Then fit the socket and the ratchet handle, and fit the strut lock straight through. The central strut is held steady, and the securing nut is quickly removed.

Specifically designed for repairing and replacing shock absorbers and struts
Contents: 7 - Go Thru' deep sockets: 16/17/18/19/21/22/24mm
3 x 1/2"D Hex bits: 6mm/7mm/8mm,
