Questions, answered

Yes — we ship parts anywhere in the world. If shipping isn't set up for your region, email sales@horizonmotorsport.com or DM @horizon.motorsport for a shipping quote.

Duties and import taxes are the buyer's responsibility and are not included in the shipping fee.

Every order ships fully insured for its full value at no extra cost. If your package arrives damaged, email sales@horizonmotorsport.com within 10 days of delivery with photos of the damaged item, the original packaging, and the shipping label. We'll file the claim on your behalf and work toward a replacement, repair, or refund.

For confirmed shipping damage on domestic orders, we cover return and replacement shipping. For international orders, shipping costs may fall to the customer — we'll work with you on a fair resolution.

Important: do not install a visibly damaged part — attempting to install voids your damage claim. Hold onto all original packaging until the claim is resolved.

Once the carrier confirms delivery, Horizon's responsibility for the shipment is fulfilled. If tracking shows delivered but the package isn't there, check with neighbors and building management, contact the carrier, and email us — we'll help file a claim.

Standard orders can be cancelled at no charge before shipment — reach out as soon as possible. After shipment, the standard return process and 20% restocking fee apply.

Special order, made-to-order, custom, pre-order, or built-to-spec items cannot be cancelled, returned, or exchanged once the order is placed — production or procurement begins immediately. Products are marked accordingly on the product page. If you're unsure, contact us before ordering.

Some. Our in-house HM-branded line (skid plates, intakes, select carbon fiber) is designed and engineered by us. Everything else is sourced from a short list of manufacturing partners — primarily in Asia, with a handful in Mexico and the US — that we've vetted over 7+ years.

We spend most of our time upstream: comparing material quality, finish consistency, and fitment tolerances across suppliers before a part even makes our catalog. By the time you see it on our site, it's passed our internal benchmarks — which is the real difference between ordering from us and rolling the dice on a random seller.

We specialize in BMW M-chassis (F80, F82, F83, F87, G80, G82, G87, plus classics like E46/E90 M3). If your car is in that family but a specific year isn't listed, message us — fitment often carries over and we'll confirm.

For non-M BMWs we can sometimes help, but it's not our core focus.

Most bolt-ons are plug-and-play. A handful of parts (certain intakes, downpipes, exhaust valvetronic mods) benefit from a tune or coding — when that's the case, it's called out clearly on the product page under FITMENT.

The following are final sale and cannot be returned or exchanged:

• Items that have been installed or modified in any way (sanding, drilling, adhesive, painting, wrapping)
• Suspension components of any kind — springs, coilovers, control arms, sway bars, end links, camber arms, etc.
• Special order, made-to-order, custom-built, built-to-spec, or pre-order items
• Items returned after the 21-day window
• Items missing original packaging or not in resalable condition

We strongly recommend dry test-fitting all parts before making any permanent modifications. If you discover an issue during test-fit, contact us before modifying the part.

If we ship the wrong item or a defective product, we correct it at no cost to the customer for domestic (US) orders — including return and replacement shipping.

For international orders, the customer may be responsible for shipping costs due to the higher cost of international freight, though we'll work with you to find a reasonable solution.

This is separate from ordering the wrong part yourself — in that case the standard return policy applies (21-day window, 20% restocking fee, customer return shipping). It's the customer's responsibility to verify fitment before ordering. Contact us before purchasing if you're unsure.

Certain products carry a manufacturer's warranty — typically 90 days — covering manufacturing defects only. Warranty does not cover installation damage, misuse, neglect, or wear.

Professional installation is required for warranty eligibility. We cannot initiate a warranty claim on parts installed by the owner — the manufacturer requires proof that a professional installer attempted and documented the install before a claim can be processed. Keep your installer's invoice and install photos.

Warranty claims are facilitated through Horizon — email us your order number, professional install documentation, and photos of the defect, and we'll handle it with the manufacturer. Final sale items aren't eligible for return but may still be covered under warranty for manufacturing defects.

Absolutely — reach out anytime. DM @horizon.motorsport or email sales@horizonmotorsport.com and we'll help with what we can: confirming fitment, answering product-level questions, flagging known gotchas on specific chassis, and pointing you toward the right resources.

For full step-by-step install walkthroughs, a BMW-specialist installer is going to give you the best experience — they have the tools, factory docs, and hands-on reps to get things dialed in correctly. If you'd like an installer recommendation, just ask.

Good to know: warranty eligibility requires professional installation — see Returns & Warranty above for details.

Yes — we keep a short list of BMW-specialist installers in major US metros that we trust. Email us your city and we'll share names.

Professional installation is our recommendation on every part, both for quality of the install and for warranty eligibility (see Returns & Warranty for details).
