KSP 5X120mm Wheel Spacers 12.7mm Hubcentric Forged Tuning Spacer

In this review the KSP 5X120mm wheel spacers are evaluated for BMW owners who want a simple, reliable way to push wheels outward for improved stance or to clear brakes and suspension. The single biggest reason to buy is that these spacers are real forged from 6061-T6 aluminum and CNC machined to the documented 72.56mm hub bore, delivering a precise hubcentric fit that minimizes vibration when installed correctly. They are aimed at enthusiasts who value build quality, correct fitment and a subtle but meaningful change in wheel position.

Key Features

• Real forged construction: Forged 6061-T6 aluminum provides higher strength and durability compared with cast alternatives, improving long-term reliability.
• Precise hubcentric fit: The 72.56mm center bore with a hub lip is machined to match OEM hub dimensions, helping reduce runout and vibration when mounted properly.
• Exact thickness: The 12.7mm (1/2 in) thickness moves the wheel outward enough to fix clearance or aesthetic issues without excessive offset change.
• Anodized finish: The black anodized surface resists corrosion and keeps the spacer looking clean on exposed wheel faces.
• Installation features: Circumference pockets allow prying the spacer off without damaging the material, making removal easier during maintenance.
• Clear identification: Laser-engraved sizing and part number make it easy to confirm fitment before and after installation.

Who It's For

This product is best for BMW owners with a 5X120mm bolt pattern who need a thin, hubcentric spacer to correct wheel tuck, create an aggressive stance, or clear brake calipers and suspension components. Enthusiasts who prefer forged parts and factory-style tolerances will appreciate the fit and finish.

It is less suited for drivers seeking large offset changes or thick adapters for wheel fitment extremes; those users should look for wider spacers or wheel options. Also, anyone uncomfortable with wheel torque specs or hub-centric alignment should have a professional install these spacers to avoid safety issues.

Pros & Cons

Pros

• High-quality forged 6061-T6 aluminum construction provides strength without excessive weight.
• Accurate 72.56mm hub bore and CNC machining deliver a snug hubcentric fit that most users report as vibration-free.
• Practical design features like pockets and anodized finish make installation and longevity better.
• Laser-engraved sizing helps confirm correct part before fitting.

Cons

• Some users report vibration at certain speeds, so careful installation and hub/bolt condition check are important.
• Includes only two spacers and no lug bolts; buyers must source compatible lug hardware separately for some BMW models.

Frequently Asked Questions

Will these spacers fit my BMW with a 5X120mm bolt pattern?
Yes, they are designed for 5X120mm bolt patterns and a 72.56mm hub bore, which matches many BMW models that use that specification.

Do the spacers include lug bolts?
No, the set includes two spacers, stickers and an instruction manual; compatible lug hardware may need to be purchased separately for some BMWs.

Will these cause vibration?
Most users report a vibration-free fit thanks to the hubcentric machining, but occasional vibration has been reported by some at certain speeds, so ensure clean mating surfaces and correct torque during installation.
