Verkline Rear Lightweight Tubular Subframe for FWD Mk5 / Mk6 / MQB Platform

After long CAD development based on a 3D scan of the OEM subframe, you can now buy a brand new subframe for the Mk5 / Mk6 & MQB Platform Vehicles.

Tested with CAD FEA (Finite Element Method) and road going tests

Using the same T45 tubing as in WRC cars, this subframe provides increased stiffness and mass reduction. All factory parts bolt up to this unit, meaning no other modifications are necessary.

Benefits:

Weighing only 11kg, it is saving 2kg over the OEM steel subframe
Possibility of adjusting camber, toe and bump steer for improved suspension kinematics
Additional mounting for upper control arm – provides better camber gain and roll center position (requires adjustable control arm to keep camber adjustment)
One mounting subframe position, eliminates subframe shifting under the car. No need for subframe locking kit / billet aluminium rear subframe inserts (weight savings)
Increases chassis rigidity for improved handling performance

Features:

Better access to car under body and enables wishbone changes without subframe removal
T45 (BS4T45 to BS4T100) tubing imported from UK and S355 metal sheets
ALL Components are TIG welded
Delivered Painted (powder coated) Black
Can be used with OEM wishbones or Verkline adjustable wishbones
Mounts to the OEM car body and no other modifications are needed to fit the subframe
Includes mounts for two OEM rear xenon lights sensors
Can be used with exhaust up to 4 inch (OEM positioning)
No need for subframe inserts or aluminium subframe bushings as the subframe comes with solid mounts to the car body
T45 is a very unique seamless carbon based steel tube that has been used in many applications in different industries. It is stronger than Co-Mo 4130 tubing that is also used in motorsport. It is widely used in the aerospace sector in equipment such as pilot seats and crew seats due to the materials ability to withstand high G forces without snapping or splitting. This material is a Carbon Manganese based and conforms to the full Aerospace Specification laid down by British Standards.
