Aragosta 9K/8K Type E Suspension Kit with Pillowball Upper Mounts for E85 & E86 BMW Z4 M

The Type-E series of dampers by Aragosta is a well-crafted combination of cutting-edge features from their high-performance Type-S and Type-SS coilovers. These dampers are specifically designed to excel in both spirited street driving and comfortable cruising. Key features include low-friction, WPC-treated inverted struts, height-adjustable rana springs, specially formulated synthetic damper fluid, and Aragosta’s unique low friction seals. The Type-E also boasts 12-step rebound adjustment knobs (available on select models) and pillowball upper mounts with camber adjustable options for specific applications.

The Ultimate in Smooth Performance

Crafted to perfection, the Type-E series showcases an ultra-lightweight, high-pressure forged aluminum cylinder with next-generation film treatment and Kashima coating. Through impregnating molybdenum, the cylinder gains remarkable lubricity, significantly reducing friction and enhancing durability. As a result, these dampers deliver outstanding linearity, smoothness, and traction ability, surpassing conventional hard alumite-based alternatives.

High-Precision Machining: A Testament to Performance Focus

Aragosta’s dedication to precision engineering is evident in the Type-E dampers. They achieve remarkable surface roughness accuracy, reaching 0.2 microns and 2/10000 mm for both aluminum and steel cylinders. The advanced honing treatment further enhances surface accuracy and roundness within the cylinder, an exceptional level of craftsmanship seldom seen in damper manufacturing.

Superior Finishing Technology for Enhanced Longevity

The steel cylinder and outer case undergo a state-of-the-art cationic electrodeposition coating process, renowned for its superior rust prevention, impact resistance, and overall durability. This comprehensive electrodeposition ensures even coverage throughout every corner of the thread, ensuring prolonged lifespan and maximum performance.

Equipped with High-Performance Springs as Standard

All Type-E dampers come standard with rana springs, embodying the ideal characteristics of a series-wound spring. These springs not only deliver top-tier quality and durability but also contribute to maximizing the overall damper performance.

Sharpened Internal Structure for Precise Control

Supporting Aragosta’s exceptional performance are their precision-engineered damper pistons and needles, capable of finely controlling damping characteristics even at extremely low speeds. The wide range of control, spanning from comfort to sports settings, dramatically enhances traction performance. Furthermore, the external damping force adjustment mechanism allows for precise and smooth characteristic changes across the 20-step adjustment range, catering to individual preferences and driving conditions.

High Hardness, High Efficiency WPC Processing

The Type-E’s inverted cartridge cylinder benefits from high hardness, high-efficiency WPC processing, a leading-edge technology for modifying metal surfaces. This process effectively reduces the wear coefficient and significantly improves oil film retention, a testament to Aragosta’s unwavering commitment to prioritizing performance, even in components that remain unseen.

Additional Information

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.

Shipping Policy

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.

BP Pricing Difference

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 sales@bulletproofautomotive.com with any inquiries.
