Product Details

After an extensive development and testing program, Verkline is excited to make this innovative rear subframe available to automotive enthusiasts worldwide. Crafted with precision and performance in mind, this subframe is the result of 3D laser scanning, CAD development, Finite Element Analysis (FEA) testing, and rigorous road trials.

Key Benefits:

  • 33% Weight Reduction: This lightweight subframe is 6.5 kg lighter than the OEM rear subframe, significantly reducing weight on the rear axle for improved performance.

  • Enhanced Rear Final Drive Position: The rear final drive is adjusted 10 mm up, reducing stress on the C.V. joints. This adjustment prevents premature wear on the joints, especially when lowering the vehicle.

  • Sturdy Mounting: The rubber mounts have been removed in favor of a single, bolted mounting position, preventing rear subframe shifts during high overloads.

  • Bump Steer Adjustment: The subframe features additional bump steer adjustment, allowing users to modify the bump steer by moving the rear toe link pickup point up and down.

  • Polyurethane Mounts: Factory rubber mounts are replaced with race car black polyurethane mounts, reducing movement during torque transfer and enhancing drivetrain performance.

Key Features:

  • Ample Underbody Access: The subframe provides more space for underbody access, making maintenance and upgrades easier.

  • Improved Chassis Rigidity: Constructed with a tubular frame design using T45 tubing and S355 metal sheets, this subframe enhances chassis rigidity for superior handling.

  • OEM Compatibility: Verkline has retained the OEM mounting points for wishbones, sway bars, brake lines, exhaust systems, and headlight range sensors, ensuring a seamless plug-and-play installation.

  • Quality Assurance: Designed, fabricated, validated, and tested in Poland, each piece is meticulously inspected by trained staff. Weldings undergo crack detection, and the entire product is thoroughly checked before shipping.

  • Aesthetically Pleasing: In addition to its exceptional performance, the subframe boasts a stunning appearance that complements the vehicle's aesthetics.

What's Included:

  • Pre-assembled rear subframe powder coated in black (other colors available for an additional cost).

  • Set of steel lockout wishbone positioning shims (24 pcs.) for Toe Links positioning, allowing bump steer adjustment.

  • Bolt and nut kit for mounting Toe Links (Zinc plated, grade 10.9).

  • Set of steel lockout wishbone positioning shims (8 pcs.) for Camber wishbones positioning.

  • Race polyurethane mounts for the rear differential.

  • Mounting bolt for the exhaust system (Zinc plated, grade 10.9).

  • Printed installation instructions for a hassle-free setup.

Upgrade your vehicle's performance with Verkline's New Lightweight Tubular Adjustable Rear Subframe, offering weight reduction, improved handling, and enhanced rigidity. Ensure a precise and responsive driving experience with this innovative subframe.
