After long CAD development based on 3D scan of OEM subframe, tested with CAD FEA (Finite element method) and road going tests you can now buy brand subframe for rear of your Audi/VW/SEAT/Skoda cars based on MQB platform with haldex. List of cars bellow.
Using same T45 tubing as in WRC cars, our subframes provide increased stiffness and mass reduction. All factory parts bolt up to this unit, no other modifications are necessary.
This version is for cars looking to maximum lightweight solution for the rear subframe – drag cars. For cars that are used on race track (road course) we have this version – WAS-564.
– 12 kg. It is 6 kg saving over OEM steel MQB subframe or 6.5 kg savings over OEM PQ35 (TT 8J, A3 8P) steel subframe.
– Possibility of adjusting camber, toe and bump steer.
– Additional drag setup 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.
– better access to car under body and enables wishbones change without subframe removal
– T45 (BS4T45 to BS4T100) tubing imported from UK and S355 metal sheets
– all components TIG welded
– delivered painted (powder coated) black or on special order (+50 euro) any RAL color
– can be used with OEM wishbones or our 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 our aluminium subframe bushings as the subframe comes with solid mounts to the car body
What is included:
– rear subframe powder coated in back.
– 3 mm metal adjustable wishbone position shims
– printed install instructions

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 also used in motorsport. It is widely used in the aerospace sector in equipment such as pilot’s seats and crew’s 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.
Tensile: 700 – 900MPa,
0.2% Yield 620MPa minimum
Hardness Test: 201min – 262 max HB or 210min – 275max HV.
Notice: Sold for off road, track and racing applications only. Mounting the subframe may increase some noise, vibration, and harshness (NVH) in the car. Our tests on stock VW Golf 7R showed very minimal NVH increase only at idle. We strongly advice to mount the subframe in qualified and experienced workshop.
