When running 2mm or 3mm wheel spacers on an F or G chassis BMW, the OEM-length lug bolt no longer provides adequate thread engagement — you need additional shank depth to restore the factory spec. Dinan's 30mm M14x1.25 lug bolt is the correct solution: OEM cone-seat geometry, black zinc-coated steel, and precisely the shank length needed to maintain full engagement through a 2–3mm spacer. Sold as a set of 10.
Features:
+ M14x1.25 thread, OEM cone-seat geometry — F/G chassis application
+ 30mm shank length, for use with 2mm and 3mm spacers
+ Steel construction, black zinc corrosion-resistant coating
+ Set of 10
Thread sizing: E chassis BMWs typically use M12x1.5. F and G chassis models use M14x1.25. Verify your spacer thickness and chassis thread spec before ordering.
