Perfect parts and fast delivery to the UK!
“Recently purchased some diff mounts for my S2, I was very impressed with the quality of the parts, and the fit was perfect. After seeing the quality of those diff mounts etc, I don’t want to use anyone else. For this very reason, I will be placing another order for even more parts next week.”

Product Description

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 new, rust free, subframe for rear of your Audi B5 inc. A4 S4 RS4 and B4 80 / 90 Sedan/Avant inc. S2 and RS2.

Using same T45 tubing as in WRC cars, our subframes provide increased stiffness and mass reduction. Our subframe also has reinforced rear anti-roll bar mount. All factory parts bolt up to this unit, no modifications are necessary.

– all components TIG welded
– delivered painted (powder coated) black or on special order (+50 euro) any RAL color
– solid mounts to the car body for increased stiffness and additional mass reduction
– reinforced rear anti-roll bar mount. No other reinforcement necessary (weight savings)
– can be used with OEM wishbones
– mounts to the OEM car body and no other modifications are needed to fit the subframe
– includes extra hole 25 mm higher for drag racing -> anti-squat system

What is included:

For cars with older type rear subframe used in B4 cars, to use our subframe, newer longer type (320 mm, old type has 300 mm) of track rods have to be used (8D0 501 530) in the car.

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 also used in motorsport. It is widely used in the aerospace sector in equipment such as pilot’s seats and crew’s 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:
– 8D0505235J / 8D0 505 235J

Notice: Sold only for off road, track and racing applications. We strongly advice to mount the subframe in qualified and experienced workshop that would know what are doing.

frequently asked questions

Is this product in-stock?

We keep 100s of Verkline products in-stock at any one time. If you urgently require a product please message the team prior to ordering to confirm stock availability.

 Can I install this myself?

Installation instructions are provided for almost all products to aid with installation.

What’re the benefits of adjusting the roll centre?

Without getting too deep into it, generally speaking, the higher the roll centre the less the vehicle will roll, the lower the roll centre the more the car will roll. Talking about road cars which are adapted to motorsport, on lowered cars without adjustable roll centres (pretty much all cars without motorsport suspension) they tend to roll more than standard. Raising the roll centre higher repositions the roll centre so that there is less roll.

What’re the benefits of adjusting the camber?

Precisely setting the camber on your car is essential for optimising the tyres contact patch under load which evenly distributes the forces across the tyre. Too much, or too little camber can cause the load to be distributed more on the inner or outer edge which can lead to accelerated wear and poor performance.

What’re the benefits of adjusting the toe?

Precisely setting the toe on your car is essential for optimising multiple aspects which contribute to performance such as corner entry handling, tyre wear (heat) and straight line stability.

What’re the benefits of adjusting the castor?

Precisely setting the castor is very important as this can increase the amount of outside wheel negative camber gain and inside wheel positive camber gain when cornering, further improving the tyre contact patch, whilst running less ‘static’ camber for reduced tyre wear in a straight line.

What’re the benefits of adjusting bump steer?

Bump-steer adjustment can reduce or increase the amount of toe change there is with suspension travel.

What’re the benefits of adjusting camber gain?

Camber-gain adjustment can reduce or increase the amount of camber change there is with suspension travel.

 What’re the benefits of eliminating deflection?

Factory rubber bushes allow for the suspension to move around in ways that allow the wheel alignment to change as they load up, making your car feel less precise and often more unstable. With the Verkline spherical bearings there is no movement which results in a direct and consistent feeling.

What is the warranty on these products?
