Do the BILSTEIN B16 PSS9 Coilovers for GD STI fit the 2004 STI?

BILSTEIN lists this kit for the 2005 to 2007 WRX STI and the 2007 STI Limited. The 2004 STI appears on a different BILSTEIN B16 kit for the GD and GG Impreza, so check the model year against both applications before ordering.

How much lower will the GD WRX STI sit?

For the GD WRX STI, BILSTEIN quotes lowering of 20mm to 40mm at the front and 30mm to 40mm at the rear compared with the factory ride height. The B16 PSS9 Coilovers for GD set the exact height inside that range on their threaded bodies. Corner weights and wheel fitment decide how low the GD STI can run in practice.

How does the B16 PSS9 kit differ from a fixed-damping kit?

A fixed-damping kit such as BILSTEIN B14 has one valving setting for the GD WRX STI. The B16 PSS9 kit adds a 9-position adjuster on each damper, so an owner of the GD STI can soften the car for daily use and firm it up for a track day or a fast mountain road without changing any parts.

Does the kit need a wheel alignment afterwards?

Yes. Any change to ride height alters camber and toe, so the GD WRX STI needs a four-wheel alignment once the suspension has settled at its final height, and again after any later height change. Settle on the final height of the GD STI before the alignment, so it is only paid for once.

Who supports the kit after purchase?

Bulletproof Automotive does. BILSTEIN backs the B16 PSS9 kit with its Limited 5-Year Warranty, and any claim for the GD WRX STI goes through us to BILSTEIN, so the owner has one point of contact from order to support. The kit for the GD STI is made in Germany to the standard BILSTEIN applies to its original-equipment work.

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.
