AP Coilover Suspension – BMW 1 Series E81 / E82 / E87

Upgrade the suspension of your BMW 1 Series with the AP Coilover Suspension Kit, combining adjustable ride height with a sport-focused damper setup for improved stance, handling and everyday road performance.

AP coilovers are designed to offer a balance between sportiness, comfort and value, making them a strong option for drivers who want more adjustability than conventional lowering springs without moving to a more complex damping-adjustable suspension system.

AP part number:

11520039

Alternative reference:

GF20-039

Adjustable Ride Height

This kit provides threaded height adjustment at both the front and rear axles.

Approximate adjustment range:

• Front: 35–65mm lowering
• Rear: 35–65mm lowering

Ride height can be adjusted using the threaded spring perch, allowing the car to be set up around stance, wheel fitment and intended road use.

Galvanized Steel Construction

The coilover struts use galvanized steel construction to provide additional protection against corrosion.

Key construction features include:

• Galvanized steel damper bodies
• Corrosion-resistant spring coating
• Threaded height adjustment
• Aluminium spring perches
• Twin-tube damper construction

This makes the kit suitable for road cars that may see year-round use, provided the threaded components are kept clean and maintained correctly.

Fixed Damping Setup

This AP kit does not feature user-adjustable damping.

The dampers are pre-set by AP to provide a sportier response than standard suspension while retaining a degree of everyday ride comfort.

This makes the kit particularly suitable for drivers who want:

• Adjustable ride height
• Sportier handling
• A straightforward suspension setup
• No need to manually tune damper settings

Designed for Fast-Road Use

The AP setup is aimed primarily at road and fast-road applications.

Potential benefits include:

• Reduced body movement
• Lower centre of gravity
• Improved steering response
• More controlled cornering
• More aggressive vehicle stance
• Greater suspension adjustability than fixed lowering springs

The fixed damping configuration also makes the kit relatively simple to set up compared with more track-focused adjustable coilovers.
