Sometimes you need longer studs if running alloy wheels. The Minilite wheels (genuine) have wheel bolts with a deep sleeve arrangement, so standard studs are fine, whilst some others need longer studs. You need to measure your wheen material depth. Mini Spares could help with the correct length if you tell them the thickness of the wheel and type of wheel nut used.
