What vehicles is the TREVORA PR-1 rear diffuser compatible with?

The TREVORA PR-1 Carbon Fiber Rear Diffuser is designed specifically for the 2024 and newer BMW M5 Sedan G90 and the 2024 and newer BMW M5 Touring G99. Fitment on the G60 5 Series or other BMW models is not confirmed.

Is the PR-1 diffuser compatible with the BMW Towing Package?

No. The TREVORA PR-1 rear diffuser is not compatible with the factory BMW Towing Package, which is available on M5 models outside the North American market. Buyers with the Towing Package fitted to their vehicle should contact Bulletproof Automotive to confirm compatibility before purchasing.

Does the PR-1 diffuser retain the factory integrated rear brake light?

Yes. The PR-1 rear diffuser is specifically engineered to retain the factory integrated rear brake light in its original position. No wiring modification or relocation is required, and the brake light continues to function as standard after installation.

Does installation require drilling or permanent modification to the rear bumper?

No. The PR-1 rear diffuser integrates with the factory rear bumper without requiring drilling or permanent modification to the vehicle structure. Professional installation is recommended to ensure correct alignment across all sections of the multi-piece assembly.

How does the PR-1 diffuser improve aerodynamic performance?

The sculpted geometry of the PR-1 manages the transition of underbody airflow as it exits beneath the rear of the car, reducing turbulence at the rear end and contributing to improved aerodynamic balance at speed. On the G90 and G99 M5, where performance at higher speeds is a core part of the car's capability, the functional contribution of a well-engineered rear diffuser complements the visual upgrade with a measurable aerodynamic benefit.

Will this product require freight shipping?

Due to its size, the PR-1 rear diffuser may require freight shipping rather than standard parcel delivery. Buyers should confirm the shipping method and any associated freight costs with Bulletproof Automotive at the time of purchase before completing the order.

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.
