Reinforcement Kit

BMW subframe reinforcement kits are essential for preventing structural fatigue and failure in high-stress areas of the chassis, particularly in performance-driven and older BMW models. Over time, repeated stress, aggressive driving, and factory design limitations can lead to subframe cracking, metal fatigue, and mounting point failure, compromising handling and safety. Common issues include rear subframe tearing, misalignment, and excessive flex, which can result in clunking noises, poor suspension response, and potential structural damage. Installing a BMW subframe reinforcement kit strengthens weak points, prevents costly repairs, and enhances chassis rigidity for improved stability and longevity. Our selection of premium BMW subframe reinforcement plates and weld-in kits provides a durable, long-term solution, ensuring superior performance and reliability for daily driving and track use.

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)

Verkline's journey to develop an exceptional suspension set for the Supra A9X and BMW Z4 G29 began from day one, and it was significantly influenced by Robert from Apex Nürburgring YouTube video. With a profound understanding of high-speed driving dynamics, Verkline collaborated with Apex to craft a suspension set that pushes the boundaries of performance. Key Components in the Full Set: Rear Lightweight Tubular Subframe (WAS-401) Front Caster Adjustable Control Arms (WAS-410) Front Lower Adjustable Control Arms (WAS-411) Front Bump Steer Adjustable Tie Rod Ends (WAS-412) Front Sway Bar End Links (WAS-413) Rear Adjustable Traction Links (WAS-421) Rear Upper Adjustable Lateral Straight Links (WAS-422) Rear Upper Adjustable Lateral Bent Links (WAS-423) Rear Adjustable Toe Links with a lockout kit (WAS-424) Rear Spring Wishbone Bushings with lockout kit (WAS-425) Rear Knuckle Bushings (WAS-426) Rear Sway Bar End Links (WAS-427) Comprehensive installation and suspension setup instructions (66 printed pages) Toyota Supra A9X and BMW Z4 G29 were designed for an exhilarating driving experience on the streets, but their factory settings may not suffice for those seeking high-performance capabilities. The issue lies in rear-end bump steer, which affects the toe angle during suspension travel. The Consequences of Bump Steer: Rear toe changes unpredictably, impacting stability and handling. During hard acceleration, the rear end tilts, resulting in toe-in. Under hard braking, the rear suspension rises, leading to toe-out. Verkline's Solution: To address these issues and enhance performance, Verkline offers three suspension setup presets (Track, Street, Drag) tailored to various driving styles. These presets provide precise alignment, ride height suggestions, and arm lengths, ensuring optimal kinematics for every designated use of the car. Say goodbye to unpredictable handling issues and experience stable and controlled driving with Verkline's Suspension Set for Toyota Supra A9X and BMW Z4 G29. Transform your car's performance with the expertise of Verkline and Apex Nürburgring. Fits these models: Toyota Supra A90 Toyota Supra A91 BMW Z4 G29
