It also changes the math on your lug bolts. Push the wheel out 6 to 8mm and the factory bolts lose that much thread engagement in the hub. That is not a place to guess.\u003c\/p\u003e\n\u003cp\u003eThese Dinan lug bolts are the M12x1.5 cone seat bolts built for BMW E-chassis cars running Dinan spacers. At 35mm long, they are sized for Dinan's 6mm, 7mm and 8mm spacers, so the bolt reaches as deep into the hub as a factory bolt does on a car without spacers. Steel construction, black zinc coating, and a set of 10 covers two wheels.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy Dinan Lug Bolts Are Matched to Spacer Thickness\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eDinan sells its lug bolts in lengths paired to specific spacer sizes instead of one long bolt for everything. Too short and you lose thread engagement. Too long and the bolt can bottom out behind the hub. The 35mm length here is the one Dinan specifies for 6mm, 7mm and 8mm spacers. If you run a thicker spacer, pick the longer Dinan bolt for that size.\u003c\/p\u003e\n\u003cp\u003eThe cone seat taper matches the OEM-style seat used on BMW wheels, and the black zinc coating resists corrosion and keeps the bolts from standing out behind dark wheels.

Dinan's guide is simple: E-chassis BMWs use a 5x120 bolt pattern with M12x1.5 lug bolts. F-chassis cars use M14x1.25, and G-chassis cars use M14x1.25 on a 5x112 pattern. An M12x1.5 bolt will not fit an M14x1.25 hub. Check the thread size of your factory bolts before you order. These bolts do not affect emissions.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e10 Dinan cone seat lug bolts, M12x1.5 thread, 35mm length, black zinc coated\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eM12x1.5 thread for BMW E-chassis 5x120 hubs\u003c\/li\u003e\n  \u003cli\u003e35mm length, matched to Dinan 6mm, 7mm and 8mm wheel spacers\u003c\/li\u003e\n  \u003cli\u003eOEM-style cone seat\u003c\/li\u003e\n  \u003cli\u003eSteel construction with black zinc coating\u003c\/li\u003e\n  \u003cli\u003eSet of 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eVehicle Fitment\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eFits by chassis family, per Dinan's spacer and bolt application guide:\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBMW E-chassis with 5x120 bolt pattern and M12x1.5 lug bolts, used with Dinan 6mm, 7mm or 8mm spacers\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eExceptions: Dinan states that E39 5 Series and E-chassis X5\/X6 applications are unique and are not covered by any Dinan spacer and bolt combination.
