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

Koni suspension has taken their long running FSD (Frequency Selective Dampening) Technology and improved upon it to create their new Special Active suspension package. Improving handling while also improving the comfort of your BMW's ride, Special Active shocks and struts prove they are a top contender in the replacement suspension market.

Koni's Special Active dampers adapt to the continuous imperfect road conditions in order to provide you with a more responsive and smoother ride. Thanks to multiple generations of suspension expertise, these shocks and struts rival expensive ride control systems of newer vehicles but at a cost that is significantly lower and a capability to be retrofitted into existing vehicles.

Designed by Koni for the vehicle's original stock ride height, these are not intended to be used with lowering springs and will perform best when paired with stock springs.

For the BMW E46 M3, upgrading the rear subframe front bushings is a smart move for both performance enhancement and preventive maintenance. The rear subframe is a critical component in the E46 M3’s suspension system, and using stronger, more durable bushings helps to ensure the car’s longevity and improve its overall handling dynamics.

Features and Benefits of Upgraded Rear Subframe Front Bushings:

• Enhanced Strength and Durability: Upgraded bushings, like those from Powerflex or AKG Motorsport, are made from materials such as polyurethane or even solid aluminum. These materials are much stronger than the stock rubber bushings, which tend to wear out, crack, and degrade over time due to exposure to heat, road grime, and oils.
• Improved Handling Performance: By installing stiffer bushings, the rear subframe's movement is reduced, resulting in a more connected and responsive feel from the chassis. This leads to better handling, sharper cornering, and more precise suspension performance under load, making it ideal for track use or spirited street driving.
• Increased Rear End Stability: With stronger bushings, the subframe stays more securely mounted to the chassis, reducing the flex that can occur during hard acceleration or cornering. This helps to enhance the rear end’s stability, giving drivers more confidence, especially in high-performance driving scenarios.
• Protection Against Subframe Issues: The E46 M3 is notorious for rear subframe issues, where cracks can develop in the subframe mounting points over time. Upgrading the bushings helps distribute forces more evenly, reducing the likelihood of stress fractures and extending the life of the subframe.
• Long-Term Solution: High-quality polyurethane or solid bushings are designed to last much longer than the OEM rubber ones. They provide a long-lasting upgrade that doesn’t degrade quickly, making them a "fit-and-forget" solution for many drivers.

Installation and Considerations:

• Direct OEM Replacement: These upgraded bushings are designed to replace the factory bushings without the need for modification. However, installation can be labor-intensive, as the rear subframe must be dropped to access the bushings.
• Reinforcement Opportunity: Since the E46 M3 is known for subframe cracking, many owners opt to upgrade their bushings in combination with rear subframe reinforcement plates, which are welded to the chassis to prevent cracks from forming. This makes it an ideal time to tackle both issues together.
• Minimal Increase in NVH: Polyurethane bushings are stiffer than rubber but generally do not add a significant amount of noise, vibration, or harshness (NVH). However, solid aluminum bushings, while offering the highest performance, can introduce more NVH, which may not be ideal for daily driving.

Best Applications:

• Performance Upgrades: If you're modifying your E46 M3 for track use, autocross, or performance street driving, upgrading to stiffer rear subframe front bushings is a must for better handling and durability.
• Preventive Maintenance: Even if you're not tracking your car, replacing worn-out bushings with polyurethane or solid bushings can help prevent subframe issues and extend the life of your suspension system.
