Cheap BMW 8 Series Wheel Hub

The BMW 8 Series was produced as a single generation, the E31, from 1990 to 1999, so all cars share the same basic platform — however, engine variants across that range (from the 840i through to the 850CSi) can differ in braking and running gear due to the significant differences in power and weight they carried. A hub from another E31 is likely your closest match, but you should confirm with the breaker that the specific engine variant of their donor car matches yours, as larger-engined models may carry uprated components. Never assume fitment is guaranteed without checking against your registration.

The E31 8 Series ran from 1990 to 1999 and received a mid-life update, but it remained the same generation throughout — the fundamental suspension and hub architecture did not change with the visual updates. That said, whether a specific hub from, say, a 1992 car will cross directly to a 1997 car is worth confirming with the breaker against both registrations, as running gear can vary with engine specification changes introduced during that period. Use your registration to get an exact match rather than relying on year alone.

Trim level on the E31 8 Series does not directly determine which wheel hub you need — fitment is driven by the engine variant and the resulting brake and suspension specification, not by cosmetic or equipment differences between specifications. If you are sourcing a used hub, the engine size of the donor car is what matters most, so focus on matching that rather than worrying about spec names. Be aware that a hub from a higher-powered variant may look similar but carry different bearing or brake interfaces, so always confirm with the breaker.

Yes — wheel hubs on the BMW 8 Series are handed, meaning the nearside (NS, passenger side) and offside (OS, driver side) are not interchangeable due to the geometry of the hub and in some cases the ABS sensor position. Always tell the breaker which side you need and double-check they are quoting you the correct side from their donor vehicle. Fitting the wrong side is a common and avoidable mistake, so be specific when you contact the dismantler.

The 840i and 850i are both E31 platform cars, but the 850i is a significantly heavier and more powerful vehicle and may carry a larger brake package with correspondingly different hub specifications. The two may not be directly interchangeable, and this is exactly the kind of engine-size-driven variation that can catch buyers out on this model. Confirm with the breaker whether the hub from their donor car was fitted to an 840i or 850i and cross-reference against your registration before purchasing.

Although the E31 8 Series shares some engineering DNA with other large BMW models of the same era, wheel hubs are running-gear components tied to specific suspension geometry, brake sizing, and bearing specifications that vary between model lines. Cross-model fitment of this kind is not something that can be confirmed reliably without detailed part-number checking, so you should not assume compatibility based on the cars being from the same manufacturer or era. Ask the breaker to verify against your specific registration rather than relying on general BMW interchangeability.
