Does the Vorsteiner E46 M3 CSL rear diffuser fit the standard rear bumper?

The V-CSL rear diffuser is shaped to the E46 M3 rear bumper profile and recreates the CSL-style lower valance. It installs in the stock diffuser location on the M3 bumper; standard 3 Series bumpers use different geometry and are not compatible.

What finish options are available for the E46 M3 CSL rear diffuser?

Two options are offered: Carbon Fiber PP 1x1 Glossy with the exposed weave under clear coat, and a Primered version prepared for paint so it can be color matched to the body by a paint shop.

What is the CSL rear diffuser made from?

Vorsteiner builds the diffuser from resin pre-impregnated 1x1 weave carbon fiber, vacuum formed and cured in an autoclave at its California facility. The result is roughly 20 to 30 percent stiffer and stronger than an equivalent wet lay-up part.

Is this diffuser part of a limited run?

Yes. The V-CSL Carbon Fiber Program is limited to 103 units in honor of the horsepower per liter of the original BMW E46 CSL, and the rear diffuser is produced as part of that anniversary program.

Can I combine the CSL rear diffuser with the other V-CSL parts?

Yes. The rear diffuser is designed to pair with the rest of the V-CSL collection, including the front bumper with splitters, bootlid, and center console, for a complete CSL-inspired E46 M3 build.

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.
