E9X M3 Aluminum Transmission Undertray

The factory transmission undertray on the E9X M3 is No Longer Available (NLA) from BMW, and even when it was, the composite construction became brittle with age — cracking or breaking under normal driving, road debris, or track use.

After releasing our E9X M3 Aluminum Engine Undertray, the most common request was for a matching transmission tray. This is it: a direct aluminum replacement that reuses all of the factory mounting locations for a fully bolt-on install with no cutting or drilling, keeping the factory fit, airflow, and clean OEM+ look underneath the car.

Features

• Lightweight aluminum construction
• Direct replacement for the factory transmission undertray
• Reuses all factory mounting locations: no cutting or drilling
• Increased protection against road debris and impacts
• Maintains factory underbody airflow, OEM+ fit and finish

As enthusiasts ourselves, we know how frustrating it is when another OEM part disappears. Rather than chase down used trays that are already cracked or worn, we built a permanent replacement made to last the life of the car.

Launch note: the first 50 units are offered at an introductory price; once they're gone, pricing returns to normal. Fulfillment begins July 22nd.

Fits:

• E9X M3: DCT and 6-speed manual
