The BMW M Performance retrofit kit central locking (we reported about it in 2022) is a unique synthesis Motorsport technology and everyday practicality, which is previously unknown to us in large-scale production. For the first time, BMW is offering these models M2G87, M3G80, M4G82 and G83 the possibility of one Central locking system to convert it, as is typically used in the DTM. The modification takes the sporty design and exclusivity of the “M” to a new level by replacing the conventional fastening of the wheels with five wheel bolts Central locking screw replaced. The retrofit kit enables a special design and a very special wheel styling, for example in combination with the M Performance rims Y-spoke 963M.

BMW central locking retrofit kit

At the heart of the system are the item numbers 31208837297 and 31208837298, which Central locking wheel bearing and Central locking screws include. To ensure the uniqueness and functionality of the system, certain additional parts necessary. These include this special tools with the number 83305A89462 1-inch torque wrench (83305A5C2D3) with a measuring range of at least 1.000 Nmwhich release tool 83305A6FE33, the Aluminum paste Würth Al 1100 (83195A97536) and that Syntheso Glep 1 grease (83239407778). With a price of over 10.000,00 € The scope of delivery not only reflects the high-quality components, but also the exclusivity of the retrofit kit.

No DIY installation solution for the end user!

Each set contains four Central locking wheel bearing, Central locking screws and hub caps. However, the installation of the central locking is not for the layman thought, because it requires one Modification of the wheel suspension, whereby Bremsanlage, brake disc and wheel hub removed and replaced with the specific components. Furthermore, a precise application of Lubricants essential on the contact surfaces to reduce the coefficient of friction and correct transmission of torque to ensure. The tightening torques are heavy 930 Newton meters for the central lock and 170 Newton meter for the locking screw, which makes the use of specialized tools essential.

Better do it again!

Final is in our eyes a follow-up check of the tightening torque essential after an initial journey in order to guarantee long-term safety and performance. The switch to a Central locking system is not just a question of design, but also of technical expertise and care. The fact is: With the retrofit kit, BMW M Performance offers an exclusive and ultra-cool update for M vehicles that is otherwise only found in professional racing - an exceptional option for enthusiasts who value attention to detail and performance.
