At 15mm and 17mm, spacer thickness begins to meaningfully shift the wheel outboard — and the bolt length has to follow. Dinan's 45mm M14x1.25 lug bolt is engineered for exactly these thicknesses, providing the full thread engagement depth needed to secure the wheel properly through a double-digit spacer stack. OEM cone-seat geometry, black zinc-coated steel construction — same spec as the rest of the line, scaled for the task. Sold as a set of 10.
Features:
+ M14x1.25 thread, OEM cone-seat geometry — F/G chassis application
+ 45mm shank length, for use with 15mm and 17mm 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.
