For the E46 Convertible enthusiast who demands uncompromised feedback, the BC Racing RM Series offers a professional-grade solution. By moving the oil reservoir away from the wheel hub and brake components, the RM Series manages heat more effectively, preventing "damper fade" during long track sessions. The inclusion of front pillowball camber plates eliminates the compliant factory rubber bushings, providing direct and unmediated steering feel. Because convertibles often suffer from chassis flex, the RM Series' ability to maintain a flat cornering attitude through its stiff 12kg rear spring rate and robust inverted front struts makes it a transformative upgrade for the E46 platform. Key Features: Enhanced Thermal Management: Inverted layout moves fluid away from brake heat to maintain consistent damping performance. Camber Adjustable Top Mounts: Precision-engineered aluminum plates allow for aggressive alignment specs to maximize front-end grip. Patented Concave Locking Ring: Unique design ensures that once ride height is set, the lower mounts remain locked securely. TIG-Welded Durability: High-strength steel shock bodies with a black chrome finish for maximum corrosion resistance. Fully Rebuildable: Every component is individual and replaceable, ensuring the long-term serviceability of the system. Specifications: Vehicle Fitment: 2000–2006 BMW 3-Series (E46) Convertible (Excludes M3). Spring Rates (Default): Front: 6 kg/mm | Rear: 12 kg/mm. Damping Curve: Linear.

For the E46 M3 Convertible owner who demands uncompromised geometry control, the BC Racing HM Series offers a motorsport-first engineering solution. By utilizing an inverted strut layout with a much larger internal piston shaft, the HM Series excels in maintaining wheel alignment during extreme lateral cornering—a critical factor for the MacPherson strut-equipped M3. The addition of external reservoirs ensures the damping fluid remains cool, preserving valving accuracy lap after lap. Standard front pillowball camber plates eliminate factory rubber "mush," providing direct and unmediated steering feedback. Because convertibles often require higher roll stiffness to compensate for chassis flex, the HM Series’ 12kg rear spring rate provides the stability needed to keep the car planted and responsive. Key Features: Enhanced Side-Load Resistance: The inverted design handles high lateral loads longer than traditional upright dampers without fatigue. Reduced Damper Fade: External canisters move fluid away from brake heat to maintain consistent lap times. Camber Adjustable Top Mounts: Precision-engineered aluminum plates allow for surgical alignment and increased turn-in bite. Patented Concave Locking Ring: BC Racing’s unique design ensures lower mounts remain securely locked even under track conditions. Fully Rebuildable: All components are individual and replaceable, ensuring the long-term serviceability of the system. Specifications: Vehicle Fitment: 2000–2006 BMW M3 Convertible (E46 Chassis). Spring Rates (Standard): Front: 8 kg/mm | Rear: 12 kg/mm (Swift Springs). Hardware: Black chrome-plated steel shock bodies and 6061-T6 aluminum components. Adjustment Type: Independent ride height, spring preload, and 2-way damping. Warranty: 1-Year limited manufacturer's warranty.

Affordable, adaptable, and built with the enthusiast in mind, the BC Racing BR Series is a proven gateway into true coilover performance. Every application benefits from extensive chassis testing and continual refinement, resulting in a setup that delivers control, confidence, and everyday usability right out of the box. Instead of relying on overly stiff spring packages, BC focuses on rates that improve handling while keeping the car livable. Matched with carefully developed damper valving, the ride feels composed and predictable rather than harsh. A mono-tube design helps control heat and maintain consistent damping under demanding conditions. The linear piston profile provides transparent feedback as grip builds, and independent ride height adjustment allows changes to stance without sacrificing travel or upsetting balance. With 30 clicks of simultaneous compression and rebound adjustment, you get a huge range of tuning—from comfortable daily duty to focused performance driving in just seconds.

For the professional-level racer or the extreme enthusiast, the BC Racing ZR Series addresses the unique geometric and thermal requirements of the E46 M3 platform. By utilizing inverted front struts with a massive 42mm piston shaft, the ZR Series provides extreme structural rigidity, preventing geometry deflection under heavy braking and cornering loads. The 3-way adjustment allows the driver to "dial in" the car for specific obstacles; for instance, softening high-speed compression to soak up aggressive curbing while keeping low-speed compression firm for immediate turn-in response. Combined with standard pillowball top mounts, this system eliminates the "mushy" feel of factory rubber, providing direct, unmediated feedback to the driver. Key Features: Reduced Damper Fade: Remote external canisters move fluid away from hot brake components to ensure consistent lap times. Camber Adjustable Top Mounts: High-quality aluminum plates allow for aggressive track alignments to maximize the tire contact patch. Pillowball Rear Mounts: Replaces rubber bushings with solid spherical bearings for increased response and precision. Patented Concave Locking Ring: BC Racing’s unique design ensures lower mounts remain securely locked, even under extreme track vibration. Fully Rebuildable: Every component is individual and replaceable, making this a long-term investment in the car's competitive potential Specifications: Vehicle Fitment: 2000–2006 BMW M3 (E46) Convertible / Coupe. Spring Rates (Default): Front: 8 kg/mm | Rear: 12 kg/mm. Construction: TIG-welded steel and CNC-machined aluminum.

For the E46 Convertible enthusiast looking to bridge the gap between a high-end street car and a dedicated race machine, the BC Racing ZX Series offers an unparalleled engineering approach. By moving the compression valving to the external canisters, the system maintains its integrity under high-stress, high-temperature conditions, effectively eliminating "damper fade." For the E46 Convertible—which lacks the structural rigidity of its coupe counterparts—the ZX Series' advanced damping provides the stability needed to maintain a flat cornering attitude. The system features bearing-mounted spring platforms to eliminate "spring binding" or popping during tight maneuvers. Fully rebuildable and customizable, the ZX Series is a long-term investment in the competitive potential of your BMW. Key Features: Enhanced Thermal Management: External canisters keep fluid away from brake heat, maintaining valving accuracy lap after lap. Camber Adjustable Top Mounts: High-quality aluminum plates eliminate factory rubber "mush," providing direct, unmediated steering feedback.

If you’re stepping into coilovers for the first time and refuse to trade comfort for capability, the BC Racing BR Series is one of the most well-rounded systems you can bolt on. Extensive chassis-specific R&D and real-world validation mean the setup arrives ready to perform — comfortable enough for daily duty, composed when the pace increases.

Dinan's Performance Spring set for the F22 M235i/M240i xDrive (AWD) provides greater control over body roll by virtue of carefully calibrated spring rates. Additionally, Dinan lowers the M235i/M240i by a 1/2" in the front and a full inch in the rear for improved suspension geometry and an even more aggressive stance. The Dinan springs are CNC wound with high tensile chrome silicon wire and shot-peened for stress relief to last the life of the car. The 10% increase in stiffness will reduce the rear suspension compression under acceleration and front suspension compression (or dive) under braking, giving your car a more controlled feel. The Dinan performance springs will also provide a noticeable improvement in grip for high-speed driving situations that will inspire confidence in your car's capabilities. The reduced body roll makes the steering more responsive to driver input and will be noticed at low speeds up to the top speed of the vehicle.

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: -1/4" (6mm)
R: -1/4" (6mm)

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).

Dinan spring specs -

F: -1" (25mm)
R: -1" (25mm)

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).
