LIGHTER & MORE STABLE

After a long CAD development, based on 3D scans of the original subframe, you now have the opportunity to upgrade your Audi Coupe Quattro with brand new, rust-free subframes.

The axle carriers are made from T45 tubes and S355 metal sheets, which are also used in rallies. These offer increased rigidity and an enormous weight reduction.

With a total weight of only 7,2 kg for the front axle subframe and 9,5 kg for the rear axle frame, you save around 5,5 kg at the front and 3,5 kg at the rear compared to the original subframe.
All components are TIG welded. The holders for mounting on the body are also designed to be very robust, so that they can withstand even the most extreme forces.

EASY INSTALLATION

The frame is easily mounted on the body using the original screw points. All original parts can also be attached to the new subframe with plug & play, which means that no further modifications are required. The original wishbones or Audi Sport wishbones can also continue to be used. In addition, the front beam has front anti-roll bar mounts, as well as mounts for 6-speed gearbox (01E). The wishbone height is also adjustable (-20mm or +20mm via OEM setting).
There are also additional reinforcements for the rear tie rods.

ALSO AVAILABLE IN YOUR FAVORITE COLOUR

You are free to choose from the entire RAL range! Simply specify the desired RAL color when placing your order. The default color is black. Another color costs €50,00 extra.

DETAILS

Note: Only available for off-road, track and racing applications. We recommend having the subframe installed by a qualified and experienced workshop.

Delivery: 1x front subframe, 1x rear subframe, front and rear anti-roll bar aluminum mounting inserts with screws, screws for fixing the body, 1x screws for the wishbones

T45 is a very unique carbon-based seamless steel tube used in a wide variety of industries such as the aerospace industry. It offers significantly better properties than, for example, Cr-Mo 4130, which is also used in motorsport.
This allows T45 to withstand extremely high G-forces without breaking or splintering.
It is carbon manganese based and conforms to full British Standards aerospace specifications.
