Camber Plates for BMW E46 M3 S54 (1999-2005)

These camber plates are perfect for the enthusiast owner who wants a high quality design with a motorsports background. Knowing a full race kit on the street is not often the best option, we took the best features from the Race Camber Plates and incorporated them into a fresh Street design -

• preserves the correct E46 M3 geometry
• separate sliding camber and caster adjustments
• maximum shock travel
• light weight
• durable materials
• large surface area
• ease of use

The Turner E46 M3 Street Camber Plates are the most advanced design on the market. These are designed specifically for the E46 M3 - no shortcuts or cookie-cutter components. We started with a fresh design to make these very user friendly and easy to install and set up. The E46 M3 front suspension has unique geometry and the strut is mounted at an angle that can put significant side loading on the strut shaft if it's not located properly. The location and angles for the main bearing were carefully engineered to allow the proper motion ratio and strut angles during adjustment. This greatly reduces bending forces on the strut itself which improves performance and longevity. By designing for one chassis we're able to focus on what works best in that application - proper fitment and operation without unnecessary adapters, easy-to-use camber and caster adjustments, and an intelligent modular design.

For street use we added a pliable urethane bushing to absorb vibration and a special base design that works with the factory radial bearing and spring perch. The radial bearing allows the spring to rotate instead of twisting and binding. By re-using the factory radial bearing we can keep the assembled stack height lower for maximized shock travel. It's also a commonly-available item that you can get from any BMW dealer at a low price. All of the things that make it work well in the factory application carry over to our design. You can use our camber plates with a stock sized spring, 60mm, or 2.5" springs. Use your stock spring perch/bearing with stock-sized springs. The 60mm and 2.5" upper spring perches are sold separately. The beauty of our design is that you can use the factory radial bearing with any of these springs.

Another important feature of the Turner Camber Plates is the size of the upper plate. Our plates have a very large surface area to better spread strut forces through the strut tower. A smaller upper plate, like those found on competitor's kits, will localize strut forces and contribute to strut tower deformation ('strut tower mushrooming'). This is a very important feature especially as these cars get older and spend more time on the track. Deformed strut towers are a serious performance and safety concern and our camber plates are properly designed to handle the loads. The factory strut reinforcement plates are not required with our camber plates (but you can use them if you want to).

Since this design is specific to the E46 M3, we can build it with the bare minimum of adapters and extra hardware. This not only cuts down on confusion but makes it easier to assemble and operate. We use the correct-sized bearing for the 16mm strut shaft; no sleeves or bearing adapters required. The original tapered lower mount support and a small stainless steel spacer from our kit are all that's required to install. We have used our camber plates with most of the major strut manufacturers on the market - stock Sachs/Boge, Bilstein, Koni, H&R, ST, and KW. Our camber plates work with any strut that is designed to accept the factory strut mount.

Building on years of building some of the most used (and talked about!) Street and Race camber plates for the E46 M3 has brought us to the next iteration of this key suspension component. Introducing the Turner Motorsport Hybrid Street/Track Caster/Camber Plate designed exclusively for the E46 M3. 

Front caster/camber plates play a key role in suspension configuration - providing a point to adjust alignment in the front of the vehicle. Without camber plates, it is not possible to dial in proper street and track alignment specifications to maximize handling and tire wear. A properly configured alignment is frequently the difference between a good car and a great car, trailing the pack and pace-setting lap times, frustrating tire wear and long tire life, or exhilarating handling and a car that fights through the turns. 

Understanding the needs of a track enthusiast, our Race camber plates allow for zero deflection and are ideal for a dedicated track vehicle. For a dedicated street vehicle, our Street camber plates are another tried-and-true option that are comfortable and perform very well. Hearing the call from customers that don't fall cleanly into one of these groups, we've designed the best of both worlds - a rebuildable polyurethane-isolated spherical bearing, or as we call it, a "hybrid" design. These camber plates deliver exceptional lifespan, high performance, with excellent road manners. 

We paid extra attention to the bearing we selected, knowing we needed a bearing that would not only be quiet, but reliable. Tens of thousands of street and track miles on a variety of applications yielded zero failures of the high quality PTFE-lined, maintenance-free stainless steel monoball spherical FK bearing. One of our secrets in enabling this high-performance bearing to function to its full potential is the 80a polyurethane isolation bushing. We identified just the right material density to allow for absorption of road noise while allowing dampers to articulate precisely and predictably. This tiny bit of cushion takes the brunt of potholes and rough roads, protecting the bearing from wear which may otherwise lead to premature failure. Equally critical to maximizing bearing life is the addition of dust seals to prevent moisture and dirt contamination.  To top it all off, the entire assembly is rebuildable in the event that, over the years, a component does wear out. 

By re-using the OEM spring perch and radial bearing, we've avoided supporting the weight of the vehicle on the strut shaft monoball - further extending the life of the bearing and mimicking a well-designed factory element. Spring perches for 60mm or 2.5" springs are also available; use of factory-style springs requires no additional perch. Inspect the shocks you plan on using these with, measuring the shock diameter (16mm or 14mm) and inspecting the seat (square or tapered) to ensure you select the correct kit for your application. Not sure which you need? Give us a call, we're happy to help. 

• Adjustable camber (3+ degrees of adjustment) and caster (2.5+ degrees of adjustment) without removing strut from the vehicle
• Wide plate assembly offers excellent load distribution to address concerns with strut tower deformation
• Compatible with factory-style springs, or with the addition of available 60mm or 2.5" perches, race-style springs as well
• Maintenance free, PTFE lined, stainless steel monoball spherical bearing for full shaft articulation
• 80A polyurethane isolation bushings for noise, vibration, and harshness (NVH) control
• Rebuildable bushing/bearing assembly with individually replaceable components

This is a NEW replacement polyurethane bushing used in our E46 M3 Front Street Camber Plates. This is a custom-manufactured part for Turner Motorsport, made with our own specifications. Replacement is straight-forward but does require the camber plates to be removed from the car. Price is for each bushing.
