Which vehicles need this 991 pasm cancellation kit?

It is for the 991 Porsche 911 GT3 and 981 Cayman GT4 (991 / 981) equipped with PASM adaptive dampers. Vehicles with conventional suspension do not need it.

What does the kit actually do?

It plugs into the factory damper harness and satisfies the vehicle electronics after the PASM adaptive dampers are removed, preventing dashboard warnings and stored fault codes.

Will this work with any coilover kit?

It is designed for use with Ohlins coilover kits, and works with conventional (non-electronic) dampers generally. If you are unsure about your combination, contact us and we will confirm.

Description

Ohlins PASM Cancellation Kit for 991 Porsche 911 GT3 / 981 Cayman GT4

This 991 pasm cancellation kit from Ohlins is required when fitting conventional coilovers to a 991 Porsche 911 GT3 and 981 Cayman GT4 equipped with PASM adaptive dampers. It plugs into the factory harness, silences suspension warnings, and prevents stored fault codes, so your Ohlins suspension performs cleanly with no electronic complaints.

Why You Need a Cancellation Kit

Vehicles equipped with factory electronically controlled dampers continuously monitor the suspension over the car’s electrical system. When those dampers are replaced with a conventional coilover kit, the missing connection triggers dashboard warnings and fault codes. The Ohlins cancellation kit plugs into the factory harness and satisfies the system, allowing the car to run aftermarket suspension cleanly, with no warning lights and no error codes stored.

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.
