Tubular lightweight subframe (front) for PQ35 platform

After long CAD development based on 3D scans of the OEM subframe, tests with CAD FEA (finite element method) and practical tests, you can now buy branded subframes for the front of your Audi/VW/SEAT/Skoda based on the PQ35 platform. The vehicle list can be found below.

By using the same T45 tubes as in WRC vehicles, our subframes offer increased rigidity and weight reduction. All factory parts are bolted to this unit, no further modifications are required.

Product advantages:

• Weighs only 6kg (13 lbs), which is 4kg (8.8 lbs) less than the OEM subframe - weight reductionof 40%!
  
• Second, higher wishbone brackets to correct the suspension kinematics for use with our tubular wishbones.
  
• A single subframe mounting position prevents the subframe from slipping under the vehicle. No subframe locking kit/deadset collar kit required (weight saving).
  
• Increased chassis rigidity for improved handling. No additional lower link strut required (weight saving)
  
• Polyurethane sway bar mount significantly reduces the forward and backward pitching of the engine, which is important for sporty riding. No additional sway bar insert or aftermarket bracket required.

Product features:

• Better access to the underbody and wishbone replacement without dismantling the subframe.
  
• T45 (BS4T45 to BS4T100) pipes from Great Britain and S355 sheets.
  
• All components TIG-welded.
  
• Supplied painted black (powder-coated) or on special order (50 euros) in any RAL color.
  
• Can be used with OEM swivel joints.
  
• Mounted on the OEM body, no further modifications required for the subframe.
  
• Including two xenon headlight brackets.
  
• Can be used with OEM underbody.
  
• Can be used with OEM or aftermarket sway bar mounts.

T45 is a unique seamless carbon-based steel tube that is used in many applications in various industries. It is more robust than Co-Mo 4130 tubing, which is also used in motorsport. It is often used in aerospace for equipment such as pilot and crew seats as it can withstand high G-forces without breaking or splintering. The material is carbon-manganese based and meets the full aerospace specifications of British Standards.

Product features:

• Tensile strength: 700-900 MPa,
  
• 0.2 % yield strength: at least 620 MPa
  
• Hardness test: 201 min.-262 max. HB or 210 min.-275 max. HV.

Replaces OEM part number:

• 1K0199313AL / 1K0 199 313AL

Note: Only available for off-road, racetrack and racing applications. Fitting this product will result in additional noise, vibration and roughness being transmitted into the cabin. We strongly recommend that the subframe is fitted by a qualified and experienced workshop.

You must use a newer Gen3 steering rack. See illustration below. The old steering rack was installed in some vehicles before 2008. It is possible to replace the old steering rack with a new one. The Gen3 steering rack requires wiring harness 1K2 971 111 AJ when installed in a vehicle with a Gen1 or Gen2 steering rack. Here you will find three links that may be helpful for the replacement: LINK1, LINK2 and LINK3. It is the customer's responsibility to check whether the modification is possible in the workshop where they wish to fit the subframe before purchasing.
