The 034Motorsport Billet Aluminum Rear Subframe Insert Kit for the BMW F2x/F3x chassis is designed to limit movement in the factory rear subframe mounts to maintain proper suspension geometry when cornering, and improve the responsiveness of the rear suspension and differential. By filling small voids in the four factory mounts as well as limiting vertical movement, this insert set eliminates the associated slop to ensure that you experience a more refined, connected driving experience, especially when driving at the limit. These billet aluminum parts will not pack and wear over time and offer a lasting performance improvement. The BMW F2x/F3x chassis use rubber rear subframe mounts that deflect under load, causing the rear end to feel vague and loose, as well as leading to less-than-optimal suspension geometry and increased understeer. These precision-machined billet aluminum inserts are designed to fill voids in the factory rear subframe mounts, and limit subframe movement without sacrificing ride quality or introducing any perceivable additional noise, vibration, or harshness into the cabin. The result is a more refined, connected driving experience, as well as improved effectiveness of aftermarket rear sway bar upgrades and suspension components. Designed to work in conjunction with the factory rubber mounts, this insert package was engineered using CAD software and thoroughly tested and refined to provide a significant improvement in handling performance and feel. These inserts were tested extensively by 034Motorsport and independent BMW enthusiasts before release on multiple F2x/F3x vehicles. Installation is very simple, can be performed in under an hour, and is completely reversible. Kit includes: (2) Upper Front Inserts (2) Upper Rear Inserts (2) Lower Front Inserts (2) Lower Rear Inserts FEATURES: 6061 Billet Aluminum Construction CNC-Machined Clear Anodized Finish for Durability Engineered to Fill Voids In Factory Rear Subframe Mounts Helps Maintain Proper Suspension Geometry When Cornering Reduces Rear Subframe Movement During Launches & Acceleration Improves Shifting Feel, Resulting in Crisper Shifts Virtually No Additional NVH Transfer Inside Cabin Easy, Straightforward Installation

The BMW F2X/F3X Chassis uses rubber differential mounts that deflect under load, causing the delay of power transfer to the rear tires, as well as leading to less-than-optimal handling characteristics during on-throttle and off-throttle transitions. These precision-machined billet aluminum inserts are designed to fill voids in the factory rear differential mounts, and limit differential movement under load without sacrificing ride quality or introducing any perceivable additional noise, vibration, or harshness into the cabin. The result is a more refined, connected driving experience. Designed to work in conjunction with the factory rubber mounts, this insert package was engineered using CAD software and thoroughly tested and refined to provide a significant improvement in handling performance and feel. These inserts were tested extensively on 034Motorsport's in-house F30 BMW 340i Development Vehicle before release. Installation is very simple and is completely reversible. FEATURES: CNC-Machined Billet 6061 Aluminum Construction with Clear Anodized Finish Application-Specific Design for Optimal Fitment and Performance Engineered to Fill Voids in Factory Differential Mount Bushings Reduces Rear Differential Movement During Shifting, Acceleration, and Deceleration Virtually No Additional NVH Transfer Inside Cabin Straightforward Installation WHAT’S INCLUDED: (Qty. 2) Front Bushing Inserts (Qty. 1) Rear Bushing Insert (Qty. 1) Insert Washer PART NUMBER EXCHANGE: Front Bushing: 33 31 6 792 513 (33316792513) Rear Bushing: 33 31 6 880 637 (33316880637)

Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) factory rubber subframe bushings were engineered to provide a balance of control while keeping the ride quality soft and supple. As a factory bushings age, they become brittle and begin to harden. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver. 

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.
