German automaker BMW has released its factory Motorsport parts catalogs intended for track and racing use to customers in the U.S. for the first time.

“Now, for the first time ever in the United States, you can purchase authentic BMW Motorsport parts to offer true BMW performance, available at select BMW centers. It’s the only way to push your track-approved BMW model to its limits,” the company announced in its website.

The launching of the Motorsports catalogs, which were previously available only in Europe, aims to increase BMW’s impact on motorsports as it competes at the American Le Mans Series through a partnership with the Rahal Letterman Racing Team, the company said in a statement.

The catalogs include parts and components for the Z4 (2009 to current) M3 (1995 to current ) and 3 Series sedan (2006 to current). They feature parts from full-on race engines and body pieces to the smallest O-rings and assorted gaskets.

Motor Trend reported that currently only four BMW dealers in the U.S. have been authorized to handle these parts, which included BMW dealerships in Westmont, Illinois; Atlanta, Georgia; Stratham, New Hampshire; and Solon, Ohio.
