What does the KW ESC Module for 991 do?

It replaces the signal the factory adaptive dampers send to the car once those dampers are removed for a KW coilover installation. Without it the car logs faults and puts warnings on the instrument cluster. The module keeps the vehicle electronically satisfied that its original suspension is still connected.

Do the in-cabin drive modes still work?

Yes. The module maintains the function of the drive mode selection inside the cabin after the factory electronic dampers have been removed, so the mode switch continues to operate normally rather than returning an error. Damping itself is then set by hand on the KW coilovers.

Do I need this module with KW coilovers?

Only if the car left the factory with electronically adjustable dampers. Where it did, removing that hardware to fit conventional coilovers requires this module to prevent fault codes and dashboard warnings. A car built without adaptive damping does not need it at all.

Is the ESC Module for 991 a plug-in installation?

The module connects into the existing factory damper wiring in place of the original units. It is normally fitted at the same time as the coilover kit, since both jobs involve the same connectors, and no dealer coding or software work is required for the module itself.

Which vehicles does this module cover?

This part number covers the Porsche Boxster, Cayman and 911 built between 2012 and 2025, across 28 listed variants shown under Applications. KW builds separate modules for other generations, so match the part to the exact chassis before ordering.

Where is the KW ESC Module for 991 made?

KW designs and manufactures the module at its headquarters in Fichtenberg, Germany, alongside the coilover systems it is built to work with. KW has produced suspension there since 1995 and supplies vehicle manufacturers, professional tuners and race teams worldwide.

Description

KW ESC Module for 991 Porsche Boxster, Cayman and 911

KW’s ESC Module for 991 Porsche Boxster, Cayman and 911 is the small component that makes a proper coilover conversion possible on a car built around its own adaptive dampers. Remove those dampers and the car objects immediately, with fault codes and cluster warnings no amount of mechanical work will silence. This module, developed and built by KW in Fichtenberg, Germany, takes the place of the factory damper signal so the car accepts the change, and it keeps the in-cabin drive mode selection working as before. It is not a part anyone buys for its own sake; it is the part that lets the suspension underneath be chosen on merit rather than dictated by the wiring loom.

Why It Is Needed

Vehicles delivered with electronically controlled dampers expect to see them on the bus, and fitting conventional KW coilovers removes that hardware, which the control unit reads as a fault. The ESC Module for 991 supplies what the control unit is looking for, so the dashboard stays clean and the drive mode switch keeps functioning, while damping is set by hand at the coilover itself.

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.
