The oversized tabs are designed to work with the original oil pump disc, so drilling smaller holes in the disc is not required. The D300 will also work with our rebuilt vanos without any other modifications.
The D300 hub price includes a fully refundable $50 core deposit for your old hub (broken or not). You can return your old hub to us using the supplied UPS return label in the box and we will refund your $50 core deposit to you within 1-2 business days for a net price of $800.
