Wheel bolt thread — required, one choice for the whole order Not sure which thread your car uses? Remove a wheel bolt and measure it before ordering — you’ll need to check it against ours before fitting anyway.

Check before fitting: you must measure a bolt from your car and confirm the bolts you fit match it and that their threaded part is longer by the thickness of the spacer you’ve bought, then tighten to your manufacturer’s torque setting. Bolt checksBefore we dispatch: Once the order has been placed, we will email to confirm the model, make and year of the car to ensure that the bolts are correct before dispatch.

What's included

In every kit

2× hubcentric wheel spacers — bored to 74.1mm, in your chosen thickness

10× extended wheel bolts — M12×1.5 conical-seat. Standard bolts have about 26mm of thread; the threaded part of ours is extended by your wheel spacer's thickness (for example, 46mm of thread for a 20mm wheel spacer). We make every effort to send the correct bolts, but you must check them against the bolts on your car before fitting — thread, seat and threaded length. See bolt checks below. If your car uses wheel nuts and studs (not bolts), this kit will not work for you. Get in touch to see if we can help.

Before we dispatch: Once the order has been placed, we will email to confirm the model, make and year of the car to ensure that the bolts are correct before dispatch.

Before you fit — your responsibility

Check your bolts before fitting

We make every effort to send the correct bolts for your vehicle, but vehicles vary by model year, market, trim and previous modifications — we can’t see what is fitted to your car. It is the responsibility of the buyer and whoever fits these parts to check every bolt against the car before use. Do not fit any bolt you have not checked, even if it came from us.

Before we dispatch: Once the order has been placed, we will email to confirm the model, make and year of the car to ensure that the bolts are correct before dispatch.

Measure a bolt from your car.Remove one of your existing wheel bolts and measure its thread length, thread size and pitch, and check its seat type (the shape under the head — see step 2). Measure the threaded part only — from where the thread starts to the tip, not including the head. The threaded part of the new bolt must be longer than this by the thickness of the spacer you’ve bought: for example, a bolt with 28mm of thread used with a 20mm spacer needs a bolt with 48mm of thread. Standard thread length for this fitment is around 26mm — if yours differs, stop and contact us before fitting.
Compare it with the bolts you’ll fit — including ours.Thread size, pitch, seat type and head must match your original bolt exactly. What is the seat? It’s the shape of the underside of the bolt head — the part that presses against your wheel. It’s usually either cone-shaped (called “conical” or “60° taper”) or rounded (called “ball” or “radius”). It must match the shape of the bolt holes in your wheel: the wrong shape only touches the wheel on a thin edge and can work loose. Simple check: hold your old bolt next to the new one — the underside of the heads should be the same shape.
Check the extra length matches your spacer.The threaded part of the new bolt must be longer than the threaded part of your original by the thickness of the spacer you’ve bought — for example, a 20mm spacer needs a bolt 20mm longer. If you’ve bought different thicknesses for front and rear, keep each bolt set with its own spacers.
Confirm full thread engagement.Once fitted, each bolt must engage the hub by at least as much thread as your original bolt did without a spacer — never less — without bottoming out or fouling anything behind the hub. What is thread engagement? It’s how much of the bolt’s thread is actually screwed into the hub — this is what holds your wheel on. Simple check: when you take out an original bolt, count how many full turns it takes to come out once it’s loose. After fitting, each new bolt must take at least that many full turns to screw in by hand before its head reaches the wheel. Fewer turns means less thread holding the wheel on — do not drive the car. If a bolt stops turning before its head reaches the wheel, it may be too long or cross-threaded — don’t force it. Once every bolt is in, tighten them to your vehicle manufacturer’s specified torque setting using a torque wrench — check your owner’s handbook or a main dealer for the correct figure for your car.
If anything doesn’t match, don’t fit it.Contact us with photos and measurements before fitting and we’ll sort it out.

Fitting should be done by a competent person or a professional garage. Re-check all bolts after the first 50–100 miles. Brightstone Engineering cannot accept responsibility for problems caused by fitting bolts that have not been checked against the vehicle as described above.

These BMW wheel spacers are precision CNC-machined hubcentric track-widening spacers for the 74.1mm-bore 5×120 BMW chassis — the E39 5 Series, the E38 and E65/E66 7 Series, and every X5 and X6 from the E53 through to the F15/F16. Two bolt threads run on this bore: M12×1.5 for the 5 & 7 Series and E53 X5, M14×1.25 for the E70/E71 and F15/F16 X5 and X6. Your thread is chosen on this page and applies to the whole order. Machined in the UK from aerospace-grade 6082-T6 billet aluminium, every pair is bored to exactly 74.1mm so the spacer locates on the hub register itself — the hub carries the load, not the wheel bolts.

Fitting spacers pushes the wheel outboard, reduces the effective ET offset, widens the track and gives a flush, arch-filling stance without any change to the suspension.

Available in 10mm, 12mm, 15mm, 20mm, 25mm and 30mm. Need a custom thickness? Contact us.

Fitment

Designed for BMW models with a 5×120 PCD wheel bolt pattern and the 74.1mm hub bore. Two bolt threads run on this bore — pick the one that matches your chassis from the table below — you confirm it on this page, and the kit ships with the matching extended bolts.

Model	Chassis	Years	PCD	Bore	Thread	Seat
BMW 5 Series	E39	1995–2003	5×120	74.1 mm	M12×1.5	60° conical
BMW 7 Series	E38	1994–2001	5×120	74.1 mm	M12×1.5	60° conical
BMW 7 Series	E65 / E66	2001–2008	5×120	74.1 mm	M12×1.5	60° conical
BMW X5	E53	1999–2006	5×120	74.1 mm	M12×1.5	60° conical
BMW X5	E70	2006–2013	5×120	74.1 mm	M14×1.25	60° conical
BMW X5	F15 / F85	2013–2018	5×120	74.1 mm	M14×1.25	60° conical
BMW X6	E71	2008–2014	5×120	74.1 mm	M14×1.25	60° conical
BMW X6	F16 / F86	2014–2019	5×120	74.1 mm	M14×1.25	60° conical

All models above use 5×120 PCD and a 74.1mm hub bore. The E39, E38, E65/E66 and E53 X5 take M12×1.5 wheel bolts; the E70, E71, F15/F85 and F16/F86 X5 and X6 take M14×1.25 — choose your bolt thread on this page. Always confirm your vehicle's hub bore and bolt thread before ordering.

Not for the E46/E90 3 Series, E60/E61 5 Series, E63/E64 6 Series or the F10/F30-generation saloons — those are 5×120 with a 72.6mm bore. See the 72.6mm kit for those.

Wheel bolt requirement

Supplied with extended wheel bolts in your chosen thread. The correct length is:

required bolt length = OEM bolt length + spacer thickness

OEM shank length on these chassis is approximately 26mm . Minimum thread engagement must be at least 1.5× the bolt diameter. Bolts (M12×1.5 or M14×1.25 to match your selection) have a 60° conical (taper) seat to match BMW OEM alloy wheels; if you run aftermarket wheels with a ball / radius seat you will need ball-seat bolts instead — the seat is set by the wheel, not the spacer.

Fitting & bolt checks

Professional fitting recommended. Before fitting, you must check the bolts against your car.

Measure a bolt from your car. Remove one of your existing wheel bolts and measure it. Measure the threaded part only — from where the thread starts to the tip, not including the head. The threaded part of the new bolt must be longer than this by the thickness of the spacer you've bought: for example, a bolt with 28mm of thread used with a 20mm spacer needs a bolt with 48mm of thread.
Compare it with the bolts you'll be fitting — whether supplied by us or sourced yourself. Thread size, pitch, seat type and head must match your original.
What is the seat? It's the shape of the underside of the bolt head — the part that presses against your wheel. It's usually either cone-shaped (called "conical" or "60° taper") or rounded (called "ball" or "radius"). It must match the shape of the bolt holes in your wheel: the wrong shape only touches the wheel on a thin edge and can work loose. Simple check: hold your old bolt next to the new one — the underside of the heads should be the same shape.
Check the extra length. The threaded part of the new bolt must be longer than the threaded part of your original by the thickness of the spacer you've bought.
Confirm thread engagement. Once fitted, every bolt must engage the hub by at least as much thread as your original bolt did without a spacer — never less.
What is thread engagement? It's how much of the bolt's thread is actually screwed into the hub — this is what holds your wheel on. The spacer moves the wheel further out, which is why the bolt needs to be longer. Simple check: when you take out an original bolt, count how many full turns it takes to come out once it's loose. After fitting the spacer and wheel, each new bolt must take at least that many full turns to screw in by hand before its head reaches the wheel. Fewer turns means less thread holding the wheel on — do not drive the car. If a bolt stops turning before its head reaches the wheel, it may be too long or cross-threaded — don't force it. Once every bolt is in, tighten them to your vehicle manufacturer's specified torque setting using a torque wrench — check your owner's handbook or a main dealer for the correct figure for your car.
If anything doesn't match, do not fit them — contact us first.

We make every effort to send the correct bolts, but it is the buyer's and installer's responsibility to verify them before use.

Re-check all wheel bolts after the first 50–100 miles.
