The 4–5mm spacer range is one of the most common fitments for closing the gap between wheel and arch on F and G chassis BMWs, and 33mm is the dedicated hardware match for those thicknesses. Dinan machines these bolts to OEM cone-seat spec in black zinc-coated steel — the same 60-degree cone geometry and M14x1.25 pitch as factory hardware — with the added shank length needed to restore proper hub thread engagement through a 4mm or 5mm spacer. Sold as a set of 10.
Features:
+ M14x1.25 thread, OEM cone-seat geometry — F/G chassis application
+ 33mm shank length, for use with 4mm and 5mm 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.
