If you are removing or changing the front struts or springs or replacing the upper strut mount, NOW is the perfect time to replace this upper spring perch. BMW calls it a "upper spring pocket with axial cage bearing". It's really the upper spring plate with the radial bearing set sandwiched between two plastic collars. The bearing is there to allow the spring to rotate a little before going into a bind. If there are popping noises coming from the front strut it's probably because this bearing set is worn or missing. The bearing insert is a common wear item becoming noisy, gritty, or will just fail completely. You won't feel that they're bad from driving the car but you may hear clunking or popping sounds from the front struts. You can replace the rubber mounts on the car but don't leave this part out! It may be just as worn and you won't want to put them back in the car. These are sold individually, so be sure to get two for your car.

The radial bearing set is used in some of our camber plate designs. It's compact, light weight, easy to replace, and inexpensive. It's an excellent alternative to pricey and obscure ball bearing sets found in other camber plates.

1994-2001 E38 740i, 740iL, 750iL

Upgrade your BMW's suspension with ECS Tuning Adjustable Sway Bar End Links, designed to provide up to 60mm (2.36") of adjustability. These end links allow you to eliminate sway bar preload or fine-tune it for specific racing needs and corner balancing. When installed, they improve drivetrain clearance and enhance sway bar responsiveness by reducing deflection, ensuring superior handling. Perfect for lowered vehicles using springs, coilovers, or air-ride suspension systems, these adjustable sway bar end links allow you to remove unwanted preload caused by changes in the center-to-center distance between sway bar mounting points. By adjusting the end links to a neutral position, you eliminate sway bar preload, enhancing suspension performance in various driving conditions.

The main body of the ECS Sway Bar End Links is crafted from strong, lightweight 6061-T6 billet aluminum and anodized red for superior corrosion resistance. Featuring left and right-hand threaded center sections and machined hex wrench fittings, these end links allow for quick and easy on-the-car adjustments. Zinc-plated hardware ensures secure and lasting adjustments, while the heavy-duty ball joint ends come with weather-resistant rubber boots and stainless steel wire retainers, providing superior protection against salt, rain, and ozone for extended durability. Each kit also includes zinc-plated Nyloc nuts and hardened steel washers for secure installation and improved contact surface on the sway bar.

These end links are designed, engineered, and rigorously tested by ECS Tuning to ensure the highest quality. Whether you have a lowered or stock suspension, these adjustable sway bar end links are the perfect upgrade, offering a high-quality, heavy-duty replacement that fits your specific needs.

Features:

Range of Adjustment: 215mm (8.46") to 275mm (10.82") 6061-T6 Billet Aluminum Construction: Red anodized for superior corrosion resistance Zinc-Plated Hardware: Provides durability and superior corrosion protection Right and Left-Hand Threaded Center Sections: Quick and simple on-the-car adjustments Heavy-Duty Ball Joints(M10x1.5): Weather-resistant rubber boots and stainless steel wire retainers for long-lasting durability

Like the E36 before it, the front strut towers on the E46 are notoriously weak. Under normal driving conditions with a stock, fresh suspension it is unlikely that you will ever have a problem. But with an upgraded street or race suspension with firm springs much of the energy from pounding the road is transmitted to the thin sheet metal in the strut tower. This pounding will cause the tower to deform or even crack. Look for 'mushrooming' or deformity around the holes for the three mounting studs at the top of the strut tower. The sheetmetal around the holes should really be flat and square. Poor shocks or stiff suspensions will actually cause this sheetmetal to pop up.

These factory BMW reinforcement plates will help disperse the energy and save you from costly repairs in the future. A strut brace also helps to prevent this but these plates are designed to reinforce the strut tower from the bottom. The install over your strut mount or camber plate and simply add thickness (strength) to the strut tower. They can be sandwiched in place and do not require welding.

This item fits the following BMWs:
1999-2005 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi
2001-2006 E46 BMW M3*
* - The stock M3 upper strut mount already does a good job of dispersing the loads of the suspension. These reinforcement plates will fit a stock mount for added strength but need to be trimmed to fit inside the strut tower. The are very strongly recommended for all M3s with coil over suspensions because aftermarket coil overs typically have a smaller surface area for their strut mounts.

Worn rubber differential mounts will lead to the differential twisting and shifting around in the rear subframe. Not only will this be noisy but it's bad for driver confidence and bad for the chassis as well. Even on fresh rubber bushings the differential has deflection and twist, especially if the car has been modified for more torque. Since the differential is centrally mounted in the rear subframe, with all suspension mounts interconnected, a differential with too much deflection will affect handling and could even damage the rear subframe.

These 88A urethane E46 M3 diff mounts are much stiffer than stock but still not as solid as our Turner aluminum/Delrin bushings. This set will resist twisting much better than the stock rubber mounts. Included is the front diff mount and two rear mounts in the cover.

A very common weak point on the 3 series BMW is the sheetmetal of the rear shock tower. The sheetmetal here is relatively thin and very susceptible to stress and fatigue. A worn out shock will bottom-out more often and this energy is transferred through the bump stop and into the metal chassis. Stiffer shocks and shock mounts also put more stress on the sheetmetal. Factor in age, mileage, and environmental conditions and it's not a surprise that we see shock tower failures often. BMW addressed this issue with reinforcements of their own but our's are thicker for additional strength. This kit mounts on top of the shock tower and can either be bolted or welded in place. Because of the shape of the rear shock tower, these do not fit cabrio/convertible cars.

Stock rear lower control arms offer very little adjustment for alignment, especially in lowered vehicles, due to their use of an eccentric bolt. These aftermarket performance control arms from ECS Tuning are designed for maximum adjustability, allowing you to maximize handling and minimize tire wear.

To ensure maximum reliability, ECS Tuning's control arms are constructed from strong, lightweight 6061-T6 aluminum and feature a 303 stainless steel center turnbuckle that offers over 8 degrees of fast and precise camber adjustment. The inner bushing is a stock style serviceable OEM bushing for long life and inexpensive maintenance.

Features:

Durable construction suitable for the daily driver and track car alike
8+ degrees adjustment range for dialing in any suspension and wheel/tire setup
Center located adjuster for maximum clearance during adjustment
OEM-style bushing for long life and inexpensive service
Black anodized 6061-T6 aluminum with 303 stainless steel turnbuckle
Includes new hardware
*With the exception of the stance community, most enthusiasts will need no more than a few degrees of adjustment range. Total adjustment often is dependent on wheel/tire clearances.

The E36/E46 rear trailing arm bushings (RTABs) wear out faster than any other bushing on the car. Worn RTAB will cause excessive toe alignment change and give a 'loose' or 'floaty' feeling in the rear handling. One of the reasons for this is that they over-extend during motion, stretching and twisting the rubber in all directions. These shims sit on either side of the bushing and limit the amount of extension from the bushing. Not only will you get more life from your RTAB but these will help stiffen the bushing during cornering. But during normal driving you will still have all of the comfort of the stock rubber bushings. These part about these bushings is how easy they are to install - simply slide them in place during your bushing install. They can be added to pre-installed bushings too by dropping the trailing arm and removing the cage around the bushing.

Works with stock rubber bushings only (not urethane or Delrin).

When working on the rear subframe, replacement of any rubber bushings and mounts should be performed. This is the front differential mount bushing and it takes the majority of the torquing motion of the diff when under load. The constant twisting will cause this bushing to wear out pretty fast.

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.

The upper rear shock bolts to the sheetmetal in the folding top well on convertible models. As the mileage goes up more and more stress is put on this sheetmetal and it can actually tear away from the rest of the chassis. Look for lttle cracks originating from the mouning holes. This reinforcement plate helps spread the shock loads around the sheetmetal and reduce stress in localized areas. Price is for the pair.

Upgrade your BMW's suspension with ECS Tuning Adjustable Sway Bar End Links, designed to provide up to 60mm (2.36") of adjustability. These end links allow you to eliminate sway bar preload or fine-tune it for specific racing needs and corner balancing. When installed, they improve drivetrain clearance and enhance sway bar responsiveness by reducing deflection, ensuring superior handling. Perfect for lowered vehicles using springs, coilovers, or air-ride suspension systems, these adjustable sway bar end links allow you to remove unwanted preload caused by changes in the center-to-center distance between sway bar mounting points. By adjusting the end links to a neutral position, you eliminate sway bar preload, enhancing suspension performance in various driving conditions.

The main body of the ECS Sway Bar End Links is crafted from strong, lightweight 6061-T6 billet aluminum and anodized red for superior corrosion resistance. Featuring left and right-hand threaded center sections and machined hex wrench fittings, these end links allow for quick and easy on-the-car adjustments. Zinc-plated hardware ensures secure and lasting adjustments, while the heavy-duty ball joint ends come with weather-resistant rubber boots and stainless steel wire retainers, providing superior protection against salt, rain, and ozone for extended durability. Each kit also includes zinc-plated Nyloc nuts and hardened steel washers for secure installation and improved contact surface on the sway bar.

These end links are designed, engineered, and rigorously tested by ECS Tuning to ensure the highest quality. Whether you have a lowered or stock suspension, these adjustable sway bar end links are the perfect upgrade, offering a high-quality, heavy-duty replacement that fits your specific needs.

Features:

Range of Adjustment: 255mm (10") to 315mm (12.4") 6061-T6 Billet Aluminum Construction: Red anodized for superior corrosion resistance Zinc-Plated Hardware: Provides durability and superior corrosion protection Right and Left-Hand Threaded Center Sections: Quick and simple on-the-car adjustments Heavy-Duty Ball Joints (M10x1.5): Weather-resistant rubber boots and stainless steel wire retainers for long-lasting durability NOTE: If you've modified your vehicle's suspension with aftermarket struts or coilovers, the mounting location for the sway bar end link may have moved. To confirm fitment with our adjustable end links, please measure the distance between the sway bar and the mounting location on the strut body with the vehicle at ride height and confirm that it is within the 255 mm - 315mm range of adjustment.

Genuine BMW
This is the factory BMW control arm upgrade used on the high-performance 330i ZHP Performance Package and offered by BMW as a sport retrofit. These arms are identical dimensions as the regular arms so they are a direct replacement. But they have all metal ball joints instead of plastic or rubber. This means they last a lot longer and are much stronger. We used these in our Grand Am and World Challenge E46 racecars with excellent performance.

Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.

We also recommend replacing the bushings when changing the control arms. The bushings are mounted at the back of the control arm and located the arm to the frame rail on the car. The stock bushings are rubber and will wear out sooner than the control arms themselves. With the control arm off the car now is the perfect time to also replace the bushings. Alternate part number 31122282121.

Any subframe work or reinforcement project on the rear of the E46 M3 should include a new set of subframe mounts. It's the worn rubber bushings that contribute to failed rear subframes on the E46 (but not the only reason). As the rubber gets worn, there is more flex to the mount. This flexing is then transferred to the sheetmetal in the floor where the spot welds will pop and the sheetmetal will crack. Additional force coming from stiffer suspensions and stickier tires will only increase the flexing of the mounts/chassis.

Of course, stiffer mounts would help prevent this problem but with a stiffer bushing comes ride harshness, vibration, and additional noise. Our engineers and technicians recommend replacement with the factory rubber bushings (along with the appropriate reinforcement of the floor). The rubber bushings help isolate bumps and impacts and are quiet. They are also a perfect fitment and require no maintenance.

This item is a set of 4 Original BMW rubber subframe mounts. Individual part numbers - 33 31 2 283 573 (left front), 33 31 2 283 574 (right front), and 33 31 2 283 419 (left and right rear, x 2).

Applications:
2001-2006 E46 M3, M3 CSL coupe, convertible
2007-up Z4 M Roadster, M Coupe

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.
