After much anticipation, we are pleased to release our lowering spring kit for the BMW M3 G80 platform! Taking our experience from our highly popular F80 springs, the goal with this offering was to lower the M3 by a tasteful amount while keeping ride quality the same or better than stock. After multiple prototypes and valuable user feedback, we believe that we met our goal. 

Our lowering springs are specifically designed to utilize the factory dampers. They are fully compatible with both standard as well as adaptive suspension. Each spring is made in the USA to our unique specifications for rates and geometries. The springs are made of high tensile chrome silicon and each unit is shot peened, pre-set, and 100% tested to ensure all the critical dimensions and rate/loads are within tolerance. The springs are then powder-coated with a stealth black finish for an OEM appearance.

Front Lowering: 1.4"

Rear Lowering: 0.7"

Stock Front Rate: 186 lb./in.

EMD Auto Front Rate: 194 lb./in.

Stock Rear Rate: 608 lb./in.

EMD Auto Rear Rate: 645 lb./in.

Enhance rear-end control and put more power to the ground with a straightforward 3-piece design that installs with ease. The factory rubber may favor ride comfort, but it struggles to keep up when driving gets aggressive. As it wears, the OEM bushing can soften and deform, reducing stability and allowing wheel hop to creep in when you need traction most.

Our 95A durometer polyurethane bushings solve that problem. Engineered to strike the perfect balance between soft factory rubber and harsh solid mounts, they significantly reduce differential movement without introducing excessive vibration. The result is more efficient power transfer, so your torque goes straight to the rear wheels instead of being lost in drivetrain flex.

Features & Benefits:

Minimizes differential movement and instability to help eliminate wheel hop
Two-piece 95A split polyurethane design for easier installation
Precision-fit insert reinforces the bushing and strengthens mounting points
Resistant to road salt, oils, and harsh chemicals
Compatible with dual mount differential plates
Design:

Type II Anodized 6061-T6 CNC billet aluminum inserts for superior corrosion resistance and durability.
95A Polyurethane 2-Piece Isolator.
Product Development:

Our Rear Differential Bushings are designed, engineered, tested, and quality inspected by our Research & Development team. Our development process includes leading-edge product technology: FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

The BMW G80 M3 and G82/G83 M4 Front Radius Arm Bushings (Caster Adjustable) are performance-focused components designed to optimize the suspension dynamics of these high-performance vehicles. These bushings allow for adjustable caster angles, enhancing steering response and overall handling characteristics.

Key Features:

1. Adjustable Caster Angle:

   • These bushings enable fine-tuning of the caster angle, which significantly impacts steering feel, straight-line stability, and cornering performance. Increased caster provides better tracking and stability at higher speeds while enhancing cornering grip.

2. Performance Enhancements:

   • Designed specifically for the BMW G80 M3 and G82/G83 M4, these bushings contribute to a more precise suspension setup, allowing for sharper steering and improved driver feedback. This is crucial for both track performance and spirited driving on the road.

3. High-Quality Construction:

   • Typically made from durable polyurethane, these bushings are engineered to withstand the demands of high-performance driving. They offer improved longevity and resistance to wear compared to stock rubber bushings.

4. Improved Handling Dynamics:

   • By minimizing bushing deflection, these components help maintain optimal suspension geometry, resulting in enhanced stability, reduced body roll, and better traction during aggressive maneuvers.

5. Direct Fitment:

   • Specifically tailored for the G80 M3 and G82/G83 M4 models, these bushings ensure a perfect fit and seamless integration with the existing suspension system.

6. Installation Considerations:

   • Installation involves removing the radius arm from the suspension assembly. While some experienced enthusiasts may choose to perform this upgrade themselves, professional installation is recommended for precise alignment and performance tuning.

Benefits of Upgrading to Caster Adjustable Bushings:

• Customizable Handling: The ability to adjust the caster angle allows drivers to personalize their vehicle's handling characteristics, accommodating various driving styles and conditions.
• Enhanced Stability: Improved caster settings can lead to greater straight-line stability and control, particularly beneficial during high-speed driving.
• Increased Steering Precision: Less flex in the bushings translates to more responsive steering and an overall more connected driving experience.

In summary, the BMW G80 M3 and G82/G83 M4 Front Radius Arm Bushings (Caster Adjustable) are an excellent upgrade for drivers seeking to enhance their vehicle's handling and performance. With adjustable caster capabilities, these bushings offer improved stability, precision, and a more engaging driving experience, making them ideal for both everyday use and track applications.
