How long does shipping take?
In-stock items typically ship within 3–5 business days. Preorders generally ship within 2–3 weeks. Made-to-order products, including some exhaust systems and specialty parts, have lead times listed on their individual product pages. Tracking information is provided once your order ships.
What's the difference between in-stock, preorder, and made-to-order?
In-stock products are ready to ship and typically ship within 3–5 business days. Preorders generally ship within 2–3 weeks. Made-to-order products are produced specifically for your order and may have longer lead times, which are listed on the product page.
Will this part fit my BMW?
Fitment varies by product and BMW chassis. Bimmer Source lists the compatible BMW model, chassis, and application on individual product pages. If you're unsure about fitment, contact us with your BMW model and year and we'll help verify compatibility.
Do I need professional installation?
Professional installation is highly recommended. Bimmer Source's Fitment Guarantee applies only when the product is professionally installed. DIY installation is performed at your own risk.
What is your return and refund policy?
Returns and refunds are subject to Bimmer Source's current Refund Policy. Because some products are made to order or specially produced for a specific vehicle, customers should review the applicable policy and product terms before ordering.
Do you ship internationally?
Bimmer Source currently offers shipping throughout the contiguous United States and Canada. Shipping rates are calculated based on the order's weight, dimensions, and destination.
How can I contact Bimmer Source?
You can contact Bimmer Source at support@bimmersource.us or through Instagram @bimmer_source. The team typically responds within 24 hours. For faster assistance, include your order number, BMW model/year, and a brief description of your question.
