Both bolt patterns are drilled and threaded in the same hub, so you can switch between wheel sets without changing hardware. Ideal for drift builds running Japanese-spec wheels (5x114.3) while keeping the option to run BMW-spec wheels (5x120) or vice versa.\u003c\/p\u003e\n\n\u003ch3\u003eWhat It Does\u003c\/h3\u003e\n\u003cp\u003eThe 5x120 BMW bolt pattern is uncommon in the drift wheel market, which is dominated by 5x114.3 Japanese-spec wheels. Adapters work but add unsprung weight, change offset, and introduce another failure point. Dual-drilled hubs solve that problem at the source: the hub itself has both bolt patterns drilled and threaded, so any wheel in either pattern bolts directly to the hub.\u003c\/p\u003e\n\n\u003cp\u003eThe set includes 2 front hubs and 2 rear hubs, covering all four corners of the car in one purchase. Both patterns are tapped with the OEM lug bolt thread pitch (M12 x 1.5), so factory or aftermarket lug bolts in either pattern work directly.\u003c\/p\u003e\n\n\u003ch3\u003eConstruction\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOEM 5x120 BMW bolt pattern (factory wheels)\u003c\/li\u003e\n\u003cli\u003eAdditional 5x114.3 Japanese bolt pattern\u003c\/li\u003e\n\u003cli\u003eBoth patterns tapped at M12 x 1.5 (OEM thread)\u003c\/li\u003e\n\u003cli\u003eFactory brake rotor set screw hole retained\u003c\/li\u003e\n\u003cli\u003eFront hub modeled after OEM 31226757024\u003c\/li\u003e\n\u003cli\u003eRear hub modeled after OEM 33411093567\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCritical Note: Rotor Drilling Required\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eTo properly use the 5x114.3 pattern, you must drill your OEM rotors with the additional 5x114.3 bolt pattern.\u003c\/strong\u003e The hubs come dual-drilled, but the rotors don't - you'll need to add the extra pattern to your rotors yourself, or run a rotor that's already drilled for 5x114.3 (some aftermarket options exist).\u003c\/p\u003e\n\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eVerify your specific VIN against the OEM part numbers before ordering.\u003c\/strong\u003e The front hub (OEM 31226757024) fits a wide range of BMW E36, E46, Z3, and Z4 models.
