AST Suspension 97-06 BMW 325xi (E46) 5100 Series NCO (Inverted)

If you're looking to dial in the perfect road balance for your 1997-2006 BMW 325xi (E46), the AST 5100 Series NCO (Inverted) STREET COILOVERS are a solid option. These are designed to maximize grip by giving you precise control over your car's rebound and ride height, making a noticeable difference in how the car handles during everyday driving.

AST uses a monotube damper design in these coilovers. This means they have a larger piston inside, which allows for more accurate control over the rebound damping. Because there's no aeration or foaming with a monotube setup, you get more responsive valving. The front dampers are set up as coilovers, while the rear maintains a divorced setup similar to the factory configuration. This approach helps achieve a more comfortable ride while still delivering excellent road balance. You can easily fine-tune your setup using the rebound adjustment knob, which offers 12 distinct positions, or by altering the ride height. This adjustability lets you tailor the damper's return-to-extension speed to your specific driving needs and preferences.

These coilovers come with springs and are made to work with your car's original top mounts. The rear springs have vehicle-specific, fixed rates that are determined through AST's extensive development and testing process. Since these dampers are rebuildable, you can have them serviced at a certified AST service center if any issues arise down the road, ensuring a long service life for your suspension.
