At this time, we have no information or part numbers for these parts other than previously shared by BMW. If you must respond now to a bid, we can only suggest that you use the same item you use today and increase the price by 25% as a buffer against the new part cost and compensate for new tariffs on steel and aluminum. Hopefully the increase will be less. We will post new parts as soon as the information is available, but it won't be until May at the earliest. Call with any specific questions.
