How does the residual thread work on an AP coilover kit?

The residual thread is the threading that remains outside the TÜV-tested adjustment range. Although it allows you to physically lower the car even further, the certified report is then no longer valid and an individual inspection is required.

What is the advantage of twin-tube damper technology (2-tube)?

In a twin-tube damper, the oil flows between the inner piston tube and the outer housing via controlled rebound valves. This provides sporty and stable damping while maintaining sufficient residual comfort for everyday use.

Key facts (TL;DR):
AP coilover kits allow individual lowering of up to 60 mm (and for specific car models even more). They are equipped with high-quality twin-tube damper technology, a galvanised steel alloy against corrosion and a trapezoidal thread for smooth height adjustment. All kits come with an official approval report (TÜV) and a 2-year factory warranty.

1. Technology & Features

High-quality twin-tube damper technology

The AP dampers consist of two housings: an inner tube (the piston housing) and an outer tube. During compression, the damping fluid flows via the base valve into the outer housing, after which special rebound valves allow the oil to flow back in a controlled manner during rebound. This guarantees direct response, stable cornering control and the preservation of sufficient residual comfort.

Adjustability & "The Residual Thread"

By adjusting the aluminium spring seat on the trapezoidal thread, you determine the exact vehicle height yourself. Depending on the vehicle, AP coilover kits feature a design-related residual thread outside the tested range. Note: if you lower the car further than prescribed, the report becomes invalid and an individual inspection is required.

The above price only concerns the indicative installation cost of the suspension and includes 3D alignment of your vehicle after installation.

Note: The exact installation hours depend on the condition of the vehicle. The hours are calculated afterwards. Your car must always stay with us for at least 1 working day for installation. If the spring kit needs to be adjusted via software (e.g. DCC dampers), additional costs may apply.

3. Frequently Asked Questions (FAQ)

What is the difference between an AP spring kit and an AP coilover kit?

With a regular spring kit (lowering springs) the drop is fixed and you often use the original shock absorbers. With an AP coilover kit you receive a completely new and matched system of sport dampers and springs, allowing you to set the ride height yourself to the millimetre via the threaded adjustment.

Will the car remain comfortable with an AP coilover kit?

Yes. AP sport suspensions are particularly popular due to their harmonious tuning. The dampers are set up to be sporty and dynamic to prevent the dangerous body roll in corners, yet they offer absolutely sufficient residual comfort for pleasant everyday road use.
