Send us your oil pump disc and we will CNC drill new holes which are slightly smaller than the stock holes (9.75mm), eliminating as much play as possible. This will help reduce the chances of hub tab failures when used with a stock hub, or combine it with our Cryo hub above for unmatched durability.
Send us your oil pump disc: $150
Send us your oil pump disc and we can redrill new holes at 9.75mm (smallest possible size) and send it back out the same day in most cases, or by the following business day. You will need to completely disassemble the pump, keep ALL the small parts, and just send the bare disc itself. We recommend either UPS or USPS Priority/Express for shipping so you can track the shipment, and be sure to include your contact information inside the box. Once the disc arrives we will contact you for payment (Paypal or Credit Cards accepted) and desired return shipping options. The shipping address can be found on the Contact Us page. Sorry, we do not sell the oil pump disc on a core exchange basis as they are far too valuable
The D300 hub is a stock BMW hub that has been modified with heavy-duty oil pump tabs for maximum durability. The oversized tabs are designed to work with the stock oil pump disc, so drilling smaller holes in the disc is NOT required.
