Does the BILSTEIN B12 Pro-Kit for 991 Carrera 4 work with PASM?

BILSTEIN lists this kit for the 2013 to 2019 Carrera 4 and the Carrera 4 GTS with PASM, and for the 2013 to 2019 Carrera 4S. For the Carrera 4 without PASM, BILSTEIN makes a separate B12 Pro-Kit, which Bulletproof Automotive also stocks.

What ride height range does the kit give the 991 Carrera 4?

For the 991 Carrera 4, BILSTEIN quotes lowering of 20mm to 25mm at the front and 15mm at the rear compared with the factory ride height. The springs set that height on the 991 Carrera 4, so it stays fixed once installed. The B12 Pro-Kit for 991 is rated for axle loads up to 800kg front and 1,215kg rear.

Why replace the dampers when lowering the 991 Carrera 4?

The factory dampers on the 991 Carrera 4 are valved for the factory springs. Shorter, firmer lowering springs on worn or stock dampers can leave the 991 Carrera 4 underdamped and shorten damper life. Here BILSTEIN valves each damper for its Eibach spring, which keeps the 991 Carrera 4 controlled at the new height.

Does the kit need a wheel alignment?

Yes. Lowering changes camber and toe, so the 991 Carrera 4 needs a four-wheel alignment once the new springs and dampers have settled. Because the ride height of the 991 Carrera 4 is fixed by the springs, one alignment after installation is normally all the kit asks for, unless other suspension parts change later.

Who supports the kit after purchase?

Bulletproof Automotive does. BILSTEIN backs the B12 Pro-Kit kit with its Limited Lifetime Warranty, and any claim for the 991 Carrera 4 goes through us to BILSTEIN, so the owner has one point of contact from order to support. The kit for the 991 Carrera 4 is made in Germany to the standard BILSTEIN applies to its original-equipment work.

Description

BILSTEIN B12 Pro-Kit for 991 Porsche 911 Carrera 4 with PASM

BILSTEIN’s B12 Pro-Kit for 991 Porsche 911 Carrera 4 with PASM pairs BILSTEIN dampers with Eibach Pro-Kit springs for the all-wheel-drive 991, from the 2013 Carrera 4 and 4S to the 2019 Carrera 4 GTS. It lowers the car 20mm to 25mm at the nose and 15mm at the tail, closing the wheel gap of a stock 991 without the cost or setting-up of coilovers.

Design and Performance

The kit replaces all four springs and dampers with parts BILSTEIN tunes as a set, so the lower ride height comes with damping made for it. The drop is moderate by design, which keeps travel for real roads.

About BILSTEIN

BILSTEIN was founded in 1873 by August Bilstein in Altenvoerde, now Ennepetal, Germany, where its engineers are still based. In 1957 it fitted the first monotube gas pressure shock absorber to a Mercedes-Benz series production car, and Audi, BMW, Porsche and Volkswagen are among the carmakers that have used its dampers as original equipment since. BILSTEIN develops its suspension on its own test circuit in Papenburg and on the Nürburgring Nordschleife, and it has been part of thyssenkrupp since 2005.

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.
