Stock floating center caps for BMW M-Series. These are made for stock/OEM wheels that match the size selected on this page.
Stock wheel fitment guide: This product is for stock BMW wheels that use 56mm, 68mm center caps. This page appears to offer: 68mm, 56mm. Check the guide below before ordering or contacting support.
BMW stock caps use only 56mm or 68mm sizes. If your exact year/model is not listed, enter your vehicle year, make & model on this page — we confirm whether 56mm or 68mm is correct before we build.
That does not always mean we do not carry the correct cap. Different wheel packages can use different cap sizes. Enter your vehicle year, make & model on this page — we confirm the correct size before we build.
Still no match — or running aftermarket/custom wheels? We now build custom small floating caps to your exact measurements — any vehicle, stock or custom wheels.
The BMW M-Series floating center cap with battery-free LED — the M logo stays centered and locked while your wheels spin, lit by kinetic energy with zero batteries required. Available in 56mm and 68mm with Blue, White, Red, or Rainbow LED.
Made for the full BMW M lineup and all BMW vehicles running factory 56mm or 68mm OEM center caps.

The LED option runs on zero batteries — ever. As your wheel spins, electromagnetic induction converts wheel rotation into electricity, lighting up the logo automatically the moment you start moving. It turns off when you stop and comes back on the instant you roll again. No charging. No wiring. No maintenance. Available in Blue, White, Red, and Rainbow multicolor. Simply select your preferred LED color from the variant selector above.
Constructed with a high-impact ABS plastic shell and stainless steel / anodized aluminum hardware. Fully weatherproof and car-wash safe — sealed against rain, road spray, and moisture. The UV-resistant finish won't fade, yellow, or crack over time. A precision bearing at the center keeps your logo spinning freely and silently at any speed — centered and level at 10 mph or 100 mph.
Remove your existing OEM center cap (pop or unscrew it from the hub) and snap the Float King cap directly into the same mounting point. No drilling, no wiring, no modifications to your vehicle. Comes as a set of 4 — one cap per wheel.
Enter your vehicle year, make & model on this page — we confirm the correct size before we build. All BMW models use either a 56mm or 68mm factory center cap — select the correct size from the variant dropdown. Use the paper trace method on our Sizing Guide for an accurate measurement. Sizes differ by as little as 1–2mm, so a ruler placed directly on the cap is not reliable enough.
Ready-made Stock Floaters are sized for OEM factory wheels. Running aftermarket wheels with a small center cap? We now build custom floating caps made to your exact measurements — any vehicle, stock or custom wheels. No adapters needed.
