Aragosta 7+3K/8K Type E Suspension Kit for E46 BMW M3

Aragosta’s Type-E dampers are designed to blend spirited street performance with comfortable cruising, drawing key technology from the Type-S and Type-SS coilover lineup. They feature low-friction, WPC-treated inverted struts, height-adjustable rana springs, specially formulated synthetic damper fluid, and Aragosta’s low-friction seals, along with vehicle-dependent 12-step rebound adjustment knobs at the base of each damper. Pillowball upper mounts are included, with optional camber-adjustable mounts available for select applications.

The Ultimate in Smooth Performance

• The Aragosta Type S Coilover Suspension system features an ultra-lightweight, high-pressure forged aluminum cylinder enhanced with state-of-the-art film treatment and Kashima coating. The specialized impregnation of molybdenum ensures remarkable lubricity within the cylinder itself. This results in substantial friction reduction and unparalleled durability, surpassing conventional hard alumite coatings. As a result, the coilovers deliver exceptional basic performance, offering high-level linearity, smoothness, and traction ability.

High-Precision Machining with the Highest Priority on Performance

• Aragosta places great emphasis on the precision of cylinder processing, achieving surface roughness levels of 0.2 microns and 2/10000 mm for both aluminum and steel cylinders. Additionally, they employ advanced honing treatment to enhance the surface accuracy and roundness inside the cylinder, ensuring it adheres precisely to the specified values. It is exceedingly rare for a damper manufacturer to carry out processing with such precision on all of their cylinders.

Superior Finishing Technology

• The steel cylinder and outer case undergo a top-notch cationic electrodeposition coating, which is widely regarded as the finest choice for rust prevention, impact resistance, and durability. This coating process ensures consistent electrodeposition to every corner of the thread, resulting in maximum coverage and an extended lifespan for the components.

Equipped with High-Performance Spring as Standard

• As a standard feature, all Aragosta coilovers come equipped with rana springs, embodying the epitome of a series-wound spring design. Alongside their exceptional quality and durability, these springs offer linear characteristics that play a key role in optimizing the overall damper performance.

Sharpened Internal Structure

• Aragosta’s remarkable performance is reinforced by damper pistons and needles that excel in controlling fine damping characteristics even at extremely low speeds. This broad range of control allows the dampers to adapt seamlessly from comfort-oriented settings to sportier ones, significantly enhancing traction performance. Moreover, the external damping force adjustment mechanism offers a clear characteristic change across its 20-step adjustment range, providing a smooth and direct click feel that corresponds perfectly to any desired setting.

High Hardness, High Efficiency WPC Processing

• The inverted cartridge cylinder is treated with precision shot peening (WPC processing), which stands as the leading technology for enhancing metal surfaces. In cartridge cylinders with high sway resistance, this process effectively reduces the wear coefficient and significantly improves oil film retention in the sway area. This manufacturing approach exemplifies a strong emphasis on performance, investing time and resources in parts that may not be immediately visible, yet play a crucial role in delivering exceptional results.

Features

• The premium rana springs offer unparalleled consistency in rates and exceptional durability
• High rigidity steel cylinders with Kashima coatings ensure long life and smooth operation
