Application and purpose

The presented set belongs to the Leaf springs and coil springs category and is dedicated to the rear suspension of the Audi TTS 8J generation. The set includes springs mounted on the left and right sides, which allows for the simultaneous replacement of both axle components and maintains uniform suspension performance characteristics.

The springs work with rims of a specific width, which is important when configuring wheels and tires for vehicle stability and handling. Using original suspension components reduces the risk of improper deflection, excessive body roll, and uneven wear of other suspension parts.

Construction and technical characteristics

The rear coil spring set has been designed for the sports Audi TTS 8J model, where precise handling and repeatable response to loads are crucial. The properly selected spring rate supports stability at higher speeds while maintaining comfort during everyday driving.

The springs work in conjunction with the rear axle shock absorbers, being responsible for:

• supporting the vehicle's weight and maintaining proper ride height,
• controlling deflection during acceleration, braking, and cornering,
• reducing the transmission of vibrations from the road surface to the body.

Thanks to being matched to the specific vehicle model and axle, the set ensures consistent operation with the factory suspension geometry and wheel systems with the intended rim width.

Benefits of using the original set

Choosing the original spring set for the Audi TTS 8J translates into a number of practical operational benefits:

• Structural compatibility – perfect fit for mounts, geometry, and vehicle weight without the need for modifications.
• Consistent performance on both sides – complete replacement of both rear axle springs minimizes differences in deflection and improves driving stability.
• Predictable suspension behavior – maintaining factory spring characteristics, which is especially important in a car with a sports purpose.
• Professional rim fitment – the design takes into account cooperation with wheels of a specific width, which promotes even loading of suspension components.

Condition and service application

The offered set comes from disassembly and is a used item, making it an attractive alternative to new parts while maintaining the manufacturer's original specifications. This type of component is suitable for both standard suspension repairs and for restoring factory handling parameters after previous modifications.

Replacing both rear axle springs in a single service process helps reduce differences in suspension performance, thereby improving the vehicle's predictable behavior in corners and under load.
