Rear Lightweight Tubular Subframe Drag - VAG RS3 S3 A3 TTRS TTS TT Golf Mk5 Mk6 Mk7 Seat Leon

After extensive CAD development based on a 3D scan of the OEM subframe, CAD FEA (Finite Element Analysis) testing, and road testing, you can now purchase a branded subframe for the rear of your Audi/VW/SEAT/Skoda cars based on the MQB platform with Haldex. See the list of cars below.

Using the same T45 tubing found in WRC cars, our subframes provide increased stiffness and reduced weight. All factory parts are bolted to this unit, so no other modifications are necessary.

This version is designed for cars looking for the lightest possible rear subframe solution – drag cars. For cars used on the racetrack (road course), we have this version – the WAS-564 .

Benefits:
- 12 kg. This equates to a saving of 6 kg compared to the OEM MQB steel subframe or a saving of 6.5 kg compared to the OEM PQ35 steel subframe (TT 8J, A3 8P).
- Adjustable tilt, convergence and impact.
- Additional brake system mount for upper control arm - provides improved camber gain and roll center position (requires adjustable rocker arm to maintain camber adjustment).
- Single subframe mounting position eliminates subframe movement under the vehicle. No subframe required.
locking kit / aluminum rear subframe inserts (weight saving).
- Increases chassis stiffness, improving handling.



Characteristics:
- better access to the car's chassis and the ability to replace the wishbones without dismantling the subframe
- T45 tubes (BS4T45 to BS4T100) imported from Great Britain and S355 sheets
- all elements welded using the TIG method
- delivered painted (powder coated) in black or on special order (50 euros) in any RAL color
- can be used with OEM control arms or our adjustable control arms
- Attaches to OEM bodywork and no other modifications are needed to fit the subframe
- includes mountings for two OEM xenon taillight sensors
- Can be used with exhausts up to 4 inches in diameter. OEM positioning.
- there is no need for subframe inserts or our aluminum subframe bushes as the subframe is equipped with solid mounts to the body

What's included:
- rear subframe powder coated at the rear.
- set of 3 mm metal control arm position adjustment shims for positions -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5 mm.
- printed installation instructions

Used in PQ35 and MQB platform cars (type numbers in brackets):

Audi A3/S3/RS3 (8Y 2021) AWD
Audi A3/S3 (8P and 8V and 8VFL 2012-2021) with Haldex
Audi RS3 (8V and 8FV 2013-2021)
Audi TT/TTS (8J and 8S 2006-2021) with Haldex
Audi TTRS (8J and 8S 2009-2021)

SEAT León Mk3 (5F) (2006-2013) with Haldex
VW Golf Mk5 Mk6 Mk7 Mk8 (2003) with Haldex (AWD)

Note: Does not work with Audi RS3 8P and VW Golf R32. The battery is located under the car behind the rear subframe. Our subframe can be used, but the battery compartment must be relocated.

T45 is a unique seamless carbon-based steel tube used in a variety of applications across industries. It is stronger than the Co-Mo 4130 inner tube also used in motorsports. It is widely used in the aerospace sector in equipment such as pilot and crew seats due to the materials' ability to withstand high G-forces without cracking or fracturing. This material is carbon-manganese-based and complies with full British Standards aerospace specifications.

Properties
Tensile strength: 700 – 900 MPa,
Efficiency 0.2% Minimum 620 MPa
Hardness test: 201 min – 262 max HB or 210 min – 275 max HV.

Note: Sold exclusively for off-road, track, and racing applications. Fitting a subframe may increase the vehicle's noise, vibration, and harshness (NVH) levels. Our tests on a stock VW Golf 7R showed a very minimal increase in NVH only at idle. We strongly recommend having the subframe installed by a qualified and experienced workshop.
