VERKLINE Rear Lightweight Tubular Subframe - A90/A91 Supra

After an extensive development and testing program, we made this rear subframe available to everyone. The car was 3D laser scanned, the subframe was CAD developed, we have tested the CAD model FEA (Finite element method) and performed road-going tests so you can now buy a new lightweight tubular adjustable subframe. Using the same T45 tubing as in WRC cars, our subframes provide increased stiffness, mass reduction and delivers more precise handling.

Benefits:

• 6,5 kg is lighter than the OEM rear subframe. This is 33% less weight on the rear axle of the vehicle!
• The rear final drive moved 10 mm up (around ⅜”) to reduce loads on the C.V. joints. We’re changing its position because if you lower the car down, the shafts are often in the wrong position. This is made to avoid early wear of C.V joints.
• Removed rubber mounts of a rear subframe to the body and made only one mounting position. We’ve changed our subframe to be bolted directly to the chassis through smaller mounting holes. This is made to avoid shifting the rear subframe under high overloads.
• Additional bump steer adjustment on the subframe. You can now change the amount of bump steer moving up and down the pickup point of a rear toe link.
• Replaced rear final drive rubber mountings with race car black polyurethane. Under torque, the trans moves around on factory mounts. Our polyurethane 85ShA mounts reduce this movement substantially helping with the drivetrain torque transfer to the shafts and wheels by removing the slop in the drivetrain.

Features:

• Much more space to access the underbody of the car.
• Increased chassis rigidity, thanks to tubular frame construction for improved handling performance. Made from T45 (BS4T45 to BS4T100) tubing imported directly from the steel mill and S355 metal sheets.
• We’ve kept the OEM mounting points of the wishbones, sway bar, brake line wires, exhaust system, and headlight range sensor - Plug & Play!
• Designed, fabricated, validated, and tested proudly in Poland. Every piece fabricated is validated by our trained staff. Weldings are crack detected and the whole product is checked before shipping.
• Gorgeous looks!
