KSP PERFORMANCE 15mm 5x112 Wheel Spacers for BMW 66.56mm Hubcentric – Forged 6061-T6, Anodized Pair

KSP PERFORMANCE 15mm 5x112 wheel spacers are forged 6061-T6 aluminum hubcentric adapters that safely push wheels outward 15mm to correct clearance and create a more aggressive stance for many newer BMW models.

If your wheels rub on calipers, sit too far inside the fenders, or you simply want a wider visual footprint without changing wheels or suspension, these spacers offer a precise, lightweight solution. Machined from real forged and anodized 6061-T6 aluminum, the pair is engineered to match OEM hub dimensions (66.56mm center bore) and a 5x112 bolt pattern, minimizing runout and vibration when installed correctly.

How do these spacers improve wheel clearance and stance?

By adding 15mm of offset, the adapters move the wheel flange outward, which can resolve interference with brake calipers, struts, or inner fender lips. The result is a more aggressive visual stance and corrected wheel fitment without permanent modifications.

• 15mm thickness shifts wheel outward for extra clearance.
• 66.56mm hubcentric bore aligns with OEM hubs to reduce vibration.
• Anodized finish resists corrosion and keeps a clean appearance.

What materials and manufacturing features ensure durability?

These spacers are forged from 6061-T6 aluminum, then CNC-machined to precise tolerances to maintain strength while keeping weight low. Anodization provides a protective barrier against environmental wear, and laser-engraved part info helps with identification and correct pairing.

• Real forged 6061-T6 aluminum construction for strength and lightness.
• CNC machining for accurate bolt pattern and center bore sizing.
• Laser-engraved markings and anodized surface for longevity.

How are these spacers installed and what comes in the box?

Installation requires removal of the wheel, fitting the spacer to the hub, and securing it with the appropriate bolts; some vehicles may need longer wheel bolts—contact KSP PERFORMANCE for bolt recommendations by model and year. Each package includes two 15mm spacers, KSP stickers, and a professional instruction manual; thread locker is included for secure fastening.

• Includes two 15mm spacers, instruction manual, stickers, and thread locker.
• May require longer bolts—reach out with vehicle details for correct hardware.
• Pockets around the spacer allow prying without damaging material during removal.

Will these spacers cause vibration or affect driving safety?

When matched to the hubcentric 66.56mm bore and torqued to specification, these spacers are designed to minimize runout and vibration. Proper installation, correct bolt length, and periodic torque checks are essential to maintain safe operation and to avoid uneven stresses on studs and bearings.

• Hubcentric design reduces the chance of vibration when fitted correctly.
• Follow torque specs and recheck after initial driving miles.
• Contact KSP PERFORMANCE support for fitment questions or bolt recommendations.

Who is this for: Enthusiasts and technicians working on newer BMW platforms (M3, M4, X2, X6, i3, i4 and many 1–8 Series models) who want a precise 15mm offset to fix clearance problems or achieve a wider stance without changing wheels. These spacers suit owners who prioritize OEM-style hubcentric alignment, lightweight forged construction, and those who will confirm bolt compatibility before installation.
