WAS-550 Fitting Instructions

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 front of your Audi/VW/SEAT/Skoda cars based on the PQ35 platform. List of cars bellow.

Using the 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.

Benefits:
6 kg (13 lbs), it is 4 kg (8.8 lbs) saving over OEM subframe. It is 40% savings !
second, a higher set of control arms mounts to correct suspension kinematics to be used with our tubular wishbones
one mounting subframe position, eliminates subframe shifting under the car. No need for a subframe locking kit/deadset collar kit (weight savings).
increases chassis rigidity for improved handling performance. No need for additional lower bar/member brace (weight savings)
polyurethane dogbone mount, significantly reduces engine pitching back and forwards essential for performance driving, no need for additional dog bone insert or aftermarket mount

Features:
better access to car underbody and enables wishbones to 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
mounts to the OEM car body and no other modifications are needed to fit the subframe
includes two xenon lights mounts
can be used with OEM undertray
can be used with OEM or aftermarket dogbone support (mounts)

What is included:
front subframe painted with black polyurethane dogbone mount
printed install instructions

Subframe now is made for both LHD and RHD cars !

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 pilots seats and crews 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.

Properties
Tensile: 700 900MPa,
0.2% Yield 620MPa minimum
Hardness Test: 201min 262 max HB or 210min 275max HV.

Replaces:

Notice: Sold for off-road, track, and racing applications only. Installation of this product will introduce some additional NVH (noise, vibration, and harshness) transfer into the cabin. We strongly advise mounting the subframe in a qualified and experienced workshop.

Must use newer Gen3 steering rack. See the picture below. The old rack was mounted in some cars prior to 2008. It is possible to swap the old rack to the new one. Gen3 rack requires wiring harness 1K2 971 111 AJ, when installed in a car with a Gen 1 or Gen 2 rack. Please find three links that you might find helpful with the swap LINK1, LINK2, and LINK3. It is the customers responsibility to check whether the modification is possible in a workshop he wants to install the subframe before the purchase.
