Our BMW carbon fiber parts sale covers the G80 M3, G82/G83 M4, G87 M2 and X3M/X4M, from front splitters to rear diffusers. Discounts change over time, so at any given moment some items here are at their regular price. The product page shows the current price, and a reduced part has its sale price next to the regular one.
Several of our own designs are in the sale, including the SPL1 and SPL2 splitters, the G87 M2 side skirts with winglets and both X3M/X4M front splitters. There are engine bay parts too. Sale parts have the same 1-year warranty and fitment guarantee as everything else we sell.
Sale buying guide
What the sale collection covers

Check fitment before the price
Four details trip people up in this collection. The CSL-style grille comes in versions with and without the front radar. The X3M/X4M splitters are made either for pre-LCI cars or for the 2022-on LCI. The rear corners for the M3 are different from the M4 ones, and the Performance-style mirror covers are for left-hand-drive cars. The fitment line on each product page has the final say. To compare options, go to your car's page, for example G80 M3 parts or G87 M2 parts.
Sale parts marked Coming soon
A few reduced parts are also marked Coming soon, including the X3M 3-piece diffuser and the G80/G82 diffuser with an F1-style brake light. You can order them, but they don't have a ship date yet, so ask us about timing first. Everything else usually ships within 5 business days unless the product page shows a longer lead time.
Frequently asked questions
Why isn't every item in the Sale collection marked down?
Parts can stay in this collection between promotions, so some of them are at their regular price at any given time. The product page always shows the current price: when a part is reduced, the sale price appears next to the regular price. If you only see one price, the item is at its regular price for now.
Do sale parts get the same warranty and fitment guarantee?
Yes. Every product we sell has a 1-year warranty against defects in materials and workmanship. If a sale part doesn't fit the car listed on its product page, contact us before you install it and we'll pay the return shipping for a refund or replacement. Our warranty page has the details.
Can I return a part I bought on sale?
Yes. Sale parts follow our normal return policy unless the product page marks them as clearance. You can return uninstalled parts in new condition and in their original packaging within 14 days of delivery for a refund (shipping isn't refunded), or between 14 and 30 days for store credit. We can't take back clearance items, custom orders or anything that has been installed or modified. Please read the return policy before you order.
