Product Description
OPTIMA D51R AGM batteries are ideal for track/race BMWs because it is a smaller size and lighter weight than a full-size battery. If you no longer have many of the electronics or power-drawing accessories, why are you lugging around the battery for them? The D51R is used by BimmerWorld in many of our in-house builds. But with that reduced weight and technology comes reduced size, and that means that the factory battery mounts won't work. Many BMW owners will put something together that sort of works, but it won't necessarily be an exact fit, let alone the safety issues of having a battery not securely mounted. At BimmerWorld, we can do much better than that
We've designed and manufactured high-quality, chassis-specific, billet aluminum battery mounts for precise fitment of OPTIMA D51R batteries in your BMW track/race car. Our goal was to provide an exact-fit solution that would not require any modifications to or replacement of wires, and to do so with factory-quality components and BimmerWorld's renowned attention to detail. Needless to say, that's exactly what we've done.
The OPTIMA D51R Style 3 Battery Mount Kit uses factory mounting points, includes an additional bracket for holding the power-distribution box on later models. It fits E82 1-series coupe*, E90 3-series sedan, E91 3-series wagon, E92 3-series coupe, and E85/E86 Z4 BMW models. Because the D51R is taller than standard BMW sizes, the top battery cover/tray will no longer fit. The D51R is only for track or race cars that do not carry anything in the trunk. Terminal post covers are strongly recommended if you transport anything in the trunk (even groceries).
Note for E82 1-series: The D51R is taller and the cargo floor may no longer be flat. Resting anything on top of the battery is not considered safe. We include E82 in our applications for cars that no longer have trunk interior panels and will not be transporting anything in the trunk.
We have D51R battery mounts for other BMWs as well - see chart below for all fitment options.
