KSP Hubcentric Wheel Spacers (5x120, 20mm) M12x1.5 for 72.56mm Hub Bore
Product description
Overview
If you’re trying to dial in wheel fitment, clearances, or stance on a 5-lug BMW setup, hubcentric wheel spacers like these KSP 5x120mm units are designed to make that kind of change feel straightforward. They’re built around a specific hub bore (72.56mm) and a specific stud thread pitch (M12x1.5), so they’re not the sort of thing you “make work” loosely.
On paper, they move your wheels outward by 0.79 inches (20mm), which can help with things like brake caliper clearance and correcting tire friction issues. That’s the headline benefit. The less glamorous part is that the fit depends heavily on the exact vehicle/year/chassis and the way your BMW is set up—this listing even calls out specific models/years to avoid, so double-checking matters.
What you’re really getting (and why it matters)
These KSP hubcentric wheel spacers are CNC-machined from forged 6061-T6 aluminum billet. The emphasis here is on durability rather than just looks. The surface is black anodized, intended to add resistance to corrosion, and the spacers use hardened 10.9 grade geomet bolts (conical seat extended studs are included as part of the package).
Where hubcentric design typically helps is centered support: instead of relying only on lug nuts to center the wheel/spacer assembly, the hub bore alignment is part of the system design. In practical terms, that can make wheel mounting feel more “locked-in” and reduce the odds of annoying vibrations that can show up when fitment is off.
That said, no spacer is magic if your baseline fitment is already fine. If your main goal is purely appearance, you may not need to solve clearance or friction problems—and that’s when these can feel like extra work for limited payoff.
Key points to verify before buying
Before you spend time and money installing, here are the details you should match to your vehicle:
- Fitment warning in the listing: The product notes it does not fit certain 328i models/years and specific F30 chassis variants. You’ll want to confirm you’re not in that excluded group.
- Bolt pattern: 5x120mm.
- Hub bore: 72.56mm.
- Stud/Nut thread pitch: M12x1.5.
- Spacer thickness: 20mm (the listed overall move outward is 0.79 inches).
- Recommended torque: 72–80 FT/LBS.
It also mentions that BMW lug bolts can be purchased separately (it lists an amazon search hint for specific ASINs). That’s useful if you discover your current hardware doesn’t match what’s required.
A small but important limitation: you don’t want to treat “20mm spacer” as a one-size-fits-all answer. Depending on your caliper clearance and tire setup, a spacer can help—or it can still leave you with clearance/friction issues if the rest of the setup doesn’t line up.
Build, driving feel, and real-world use
The “for what it’s for” part is pretty clear: 20mm hubcentric spacers are positioned to improve clearance and stance. The listing specifically points to fixing brake caliper clearance issues, correcting tire friction issues, and improving cornering stability (by way of stance/suspension fitment changes).
Imagine a common scenario: you install new tires and suddenly you hear rubbing on the inside edge near the suspension or caliper area. Moving the wheel outward can relieve that contact, especially when the caliper-to-wheel gap is tight. With a 20mm spacer, you’re aiming for a noticeable change, not a tiny adjustment.
Where this can be less convincing is if your problem isn’t clearance-related. If your wheel setup already clears properly and you mainly want aesthetics, spending on spacers may not feel worth it compared with simpler options like choosing different wheel widths/offsets or tire sizes.
Strengths and where it may fall short
What stands out: - CNC-machined forged 6061-T6 aluminum billet construction - Black anodized surface for corrosion resistance - Hardened 10.9 grade geomet bolts included - Hubcentric sizing based on the listed 72.56mm hub bore - The product includes a support policy (refund/replacement window is mentioned)
Where you should be cautious: - It’s not designed for every BMW in the broad “5x120” universe. The listing explicitly excludes certain 328i 2012–2013 sedan and F30 chassis variants. - Installation and safety depend on matching thread pitch and torque specs (72–80 FT/LBS is provided, but you still need to ensure your setup is correct). - If you’re expecting universal fitment without verifying year/make/model and related details, it may not suit you.
Included and essentials
The listing states you get 2pcs spacers and 10pcs conical seat extended studs. It also emphasizes support in case you have questions, and that you should recheck vehicle compatibility (year/make/model) in the product description before purchasing.
If you’re the type of buyer who likes to plan ahead, that’s a good sign: you can confirm your bolt pattern, hub bore, and thread pitch first, then decide whether 20mm is the change you actually need.
Final verdict
Is it worth it?
A solid pick if your BMW application matches the listed 5x120mm, 72.56mm hub bore, and M12x1.5 thread pitch—and you’re trying to address real clearance or tire friction problems with a 20mm spacer. If your goal lines up with what the product is meant to solve (caliper clearance, rubbing, and a more aggressive stance), it makes sense to consider.
You may want to skip it if you don’t want to verify compatibility carefully. The listing flags certain models/years as not fitting, and the spacer thickness is substantial—so mismatched fitment could create more headaches than it fixes. If you’re unsure whether your current wheel/tire setup needs a spacer, do that compatibility check first.
Mini FAQ
FAQ
Do I need different lug bolts for this setup?
The listing notes you can purchase BMW lug bolts separately if needed and provides an Amazon search hint (ASINs) for reference. If your existing hardware doesn’t match what’s required, that’s where this guidance may help.
Will 20mm spacers fix brake caliper clearance?
The listing states these can help with brake caliper clearance issues. Still, whether they solve your specific clearance depends on your wheels, offset, and tire size.
What vehicles should I avoid?
The listing specifically says they do not fit 2012–2013 328i Sedan and certain F30 chassis 328i xDrive Sedan setups. Confirm your exact year/chassis before buying.
What torque should I use during installation?
The recommended torque listed is 72–80 FT/LBS. Make sure your installation follows that guidance and that your hardware matches the setup.
Are they easy to maintain and resist corrosion?
They’re black anodized, which is intended to improve resistance to corrosion, and the listing also mentions the spacers can be dismounted more easily with special notch holes.
