Aragosta 10-20K/12-24K Type SS 2 Way Suspension Kit w/ Pillowball Upper Mounts for E90 & E92 BMW M3

As Aragosta’s flagship coilover, the Type SS is specifically designed for track-focused applications, providing a variety of custom spring rate options. These coilovers come equipped with 2-way remote reservoirs to counteract damper oil heat soak and individual adjustability for compression and rebound settings. The Type-SS also incorporates low-friction, WPC-treated inverted struts, height-adjustable Rana springs, Kashima-coated forged aluminum cylinders, specially formulated synthetic damper fluid, and Aragosta’s distinctive low friction seals.

The Ultimate in Smooth Performance

  • The Aragosta Type S Coilover Suspension system employs an ultra-lightweight, high-pressure forged aluminum cylinder treated with next-generation film treatment and Kashima coating. The unique impregnation of molybdenum ensures remarkable lubricity within the cylinder itself. This results in substantial friction reduction and unmatched durability, surpassing conventional hard alumite coatings. As a result, the coilover system delivers exceptional basic performance, showcasing high-level linearity, smoothness, and outstanding traction ability.

High-Precision Machining with the Highest Priority on Performance

  • Aragosta places a strong 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 an advanced honing treatment to enhance the surface accuracy and roundness inside the cylinder, aligning precisely with the specified values. This level of precision in processing all their cylinders is exceptionally rare among damper manufacturers.

Superior Finishing Technology

  • The steel cylinder and outer case undergo a superior cationic electrodeposition coating, widely regarded as the best choice for rust prevention, impact resistance, and durability. This coating process ensures reliable electrodeposition to every corner of the thread, providing maximum coverage and significantly extending the lifespan of the components.

Equipped with High-Performance Spring as Standard

  • As a standard feature, all Aragosta coilovers come equipped with Rana springs, which embody the ideal of a series-wound spring. Alongside their high quality and exceptional durability, these springs’ linear characteristics play a key role in maximizing the overall damper performance.

Sharpened Internal Structure

  • Aragosta’s exceptional performance is backed by damper pistons and needles capable of finely controlling damping characteristics even at extremely low speeds. This broad range of control allows the dampers to seamlessly transition from comfort-oriented settings to sportier ones, resulting in a significant improvement in traction performance. Furthermore, the external damping force adjustment mechanism offers a clear and precise 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 undergoes 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 but play a crucial role in delivering exceptional results.

Main Specifications

  • The Premium Rana springs offer unmatched consistency in rates and exceptional durability.
  • The forged aluminum cylinders, coated with Kashima, deliver exceptional strength and outstanding resistance against corrosion.
  • The high rigidity steel inverted struts, featuring cation coating, guarantee prolonged durability and seamless operation.
  • The coilovers come equipped with remote reservoirs, offering 2-way damper settings for precise fine-tuning, with 11 compression and 20 rebound characteristics to choose from.
  • Easily adjustable for height.
  • Included as standard, the coilovers feature pillowball upper mounts.

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.
Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.
We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at with any inquiries.
