The adapter bolts to your hub using extended bolts through the vehicle's original threaded holes, and the wheel then bolts directly onto the adapter's own threaded 5×112 holes. Extended bolts matched to your chosen thickness and hub era are required and sold separately.\u003c\/p\u003e\n\n  \u003cdiv class=\"be-fit-note\"\u003e\n    \u003cp\u003e\u003cstrong\u003eFitment note:\u003c\/strong\u003e the makes and models listed above are a guide to vehicles commonly using this hub and bore combination — they are not a guarantee of fitment.

Wheels drilled 5×112 with a 57.1mm bore (Audi A3\/S3\/RS3\/TT-style) need the other 57.1mm-to-57.1mm version of this adapter, not this one.\u003c\/p\u003e\n    \u003c\/details\u003e\n    \u003cdetails\u003e\n      \u003csummary\u003eDo I need to buy new bolts, or can I reuse my existing ones?\u003c\/summary\u003e\n      \u003cp\u003eYes, new bolts are needed.

As a guide, Mk3-era cars (Golf III, Jetta III, Corrado, Passat B3\/B4) use M12×1.5 bolts, while Mk4-era cars (Golf IV, Jetta IV, New Beetle, R32, Audi TT Mk1) use M14×1.5 bolts. \u003ca href=\"\/pages\/contact\"\u003eContact us\u003c\/a\u003e with your car and wheel details and we can source the correct bolts for you at an extra cost.\u003c\/p\u003e\n    \u003c\/details\u003e\n    \u003cdetails\u003e\n      \u003csummary\u003eWhat thickness should I choose?\u003c\/summary\u003e\n      \u003cp\u003e15mm gives a subtle offset change, 20mm is the most common choice for a noticeable stance improvement without pushing clearances, and 25mm is more aggressive — check clearance against your arch and suspension components before choosing 25mm.\u003c\/p\u003e\n    \u003c\/details\u003e\n    \u003cdetails\u003e\n      \u003csummary\u003eIs this adapter hubcentric on both sides?\u003c\/summary\u003e\n      \u003cp\u003eYes.
