Please ensure your correct model is selected

Information is one of the most important tools in making your car faster, handle and brake better, and just be more reliable. Supplemental gauges have long been an easy and effective method of gathering and monitoring data on how the engine is performing, cooling system performance, engine tuning, oil pressure and temp, chassis dynamics, and just about anything else you can think of. Race teams employ teams of data engineers that study and articulate changes in the never ending quest of going faster.

Data acquisition and interpretation does not have to be a black art, however. We offer products that collect and present vital information in an easy to understand display. Think of these as smartphones for your car - sophisticated, touch-button operation, easy installation, and immensely valuable.

The gears that drive the odometer in older BMW's had a habit of wearing down or breaking, leading to faulty reading on vehicle mileage. Unfortunately, these are not items you can get directly from BMW. Lucky for us, the team over at Odometer Gears started their business specifically for specialty items such as these.

Using plastic injection molding, Odometer Gears are able to create identical gears that restore perfect function to your odometer. The process is relatively simple and allows for your car to show correct mileage. 

This third gear is an E3 48x14 gear with a plastic neck and only fits E30 BMW's with the VDO gauge cluster.

This is easily determined by checking the back of the cluster when it is removed for the VDO logo on the exposed portion of the circuit board. In addition to needing to identify the specific type of gauge cluster, either VDO or MotoMeter, you must also identify the total amount of teeth this gear has. There is no way to determine this from any external part numbers and the teeth must be physically counted to ensure you are ordering the correct part. The E3 gear has 48 teeth on the outside and either 12 teeth or 14 teeth on an attached underside gear. This is the number that must be verified, 12 or 14.
