Front lightweight tubular subframe MQB - Audi TTRS TTS TT 8S RS3 S3 A3 8V Golf Mk7

The WAS-570 weighs just 6.5 kg - saving 6 kg over the steel MQB subframe and 3.5 kg (8.8 lbs) over the aluminum version (MK7.5 Clubsport, MK8). That is a 50% weight reduction from the steel variant. The savings come from T45 seamless tubular construction - the same aerospace-grade carbon manganese steel specified for FIA-homologated roll cages. T45 delivers minimum 620 MPa yield strength and 700-900 MPa tensile strength - exceeding Chromoly 4130 tubing commonly used in aftermarket motorsport fabrication. The result is a subframe that weighs half as much while providing dramatically higher torsional rigidity than both OEM variants.

The primary benefit of a tubular subframe is not weight - it is geometric consistency. Every suspension pickup point is held in a fixed position relative to the chassis, regardless of lateral, longitudinal, or combined loads. Your instant centres, roll centre heights, camber curves, and side view swing arm geometry remain where they were designed to be - throughout every phase of a corner, under braking, and on throttle. This means your alignment settings, your anti-dive behaviour, and your bump steer curves all work as intended, not as approximations that shift with every chassis flex. The result is a car that behaves predictably at the limit and responds consistently to setup changes.

The WAS-570 ships with a polyurethane dogbone mount pre-installed via a dedicated dog bone adapter (WAS-570-47-A). The red polyurethane version is standard - significantly reducing engine pitch under power while maintaining acceptable NVH for mixed use. A black, stiffer version is available for dedicated track and race applications. One fixed mounting position eliminates subframe shifting entirely - no locking kit or deadset collar required. The integrated design also eliminates the need for a separate lower chassis brace or membrane brace - the tubular structure provides equivalent or greater rigidity as a single component. Additional practical benefits: the tubular open structure enables wishbone replacement without subframe removal, and includes two xenon headlight sensor mounts as standard.

The WAS-570 you receive today is the latest production revision - the result of multiple documented engineering revisions spanning 7 years. In 2022, VERKLINE undertook a complete structural redesign: all mounting point geometry re-engineered from 3D scans of production vehicles, new welding jigs with tighter tolerances, and a universal steering rack interface that clears both MQB rack variants with a single geometry. Since that redesign: zero fitment-related complaints across the entire WAS-550/560/570 subframe family. A high revision letter is a direct indicator of product maturity - it means the part has been validated under real conditions across 30+ countries and refined based on measurable data.

VERKLINE marks every product revision with a sequential letter. Revision A is the first production version. Each subsequent letter means the product has been refined based on specific findings - whether from customer feedback, installation data, or internal testing. A high revision letter is a direct indicator of product maturity. It means the part has been validated under real conditions, refined based on measurable data, and improved where it counts. You always receive the latest production revision.

An OEM stamped subframe is designed to flex under load - the sheet metal bends and returns to shape. A tubular structure behaves differently. It is far more rigid, but when loads exceed its design envelope, it does not flex and recover - it reaches its limits. The original WAS-570 design (2019) was strong enough for road tyres and semi-slick use, but feedback from hardcore track users running full slick tyres on prepared surfaces showed that the dogbone mounting area and the wishbone brackets were not fully optimised for the extreme forces that slicks generate on circuit.

VERKLINE collected real-world data from these track users and in 2022 executed a complete redesign - not a reinforcement patch, but an entirely new subframe structure. The full design was re-developed using FEA (Finite Element Analysis) to handle slick tyre loads across the entire operating envelope. Both the dogbone mount and the LCA brackets were completely re-engineered with new geometry and reinforced load paths - while preserving the low weight that makes tubular construction worthwhile. The original compromise between strength and lightness was re-balanced at a significantly higher level.

All mounting point geometry was also re-engineered from 3D scans of production vehicles for precise fitment. Since the 2022 redesign, VERKLINE has received zero fitment-related complaints and zero structural issues across the entire front subframe product line (WAS-550, WAS-560, WAS-570). The current production versions represent the most refined designs ever produced.
