KSP 5x112mm Wheel Spacers 12mm Hubcentric 66.56mm - Forged Tuning

In this review the KSP 5x112mm wheel spacers are evaluated for drivers who want a reliable hubcentric spacer to push wheels out for fitment or stance improvements while keeping road feel stable. The single biggest reason to buy is the use of real forged 6061-T6 aluminum with a precisely machined 66.56mm hub bore that aims to mount with minimal clearance and reduce vibration; the reviewer found this build approach gives confidence in fit and lightness compared with crude cast alternatives. The pack of two, plus zinc open end acorn lug nuts and thread locker, makes these spacers a practical choice for owners of later-model Audi G-chassis cars and other 5x112 vehicles.

Key Features

• Real forged construction: 6061-T6 aluminum forging and CNC machining deliver a consistent, lightweight spacer that holds tight tolerances for hubcentric mounting.
• 66.56mm hubcentric bore: Precisely sized bore reduces runout and helps retain factory driving feel when installed correctly.
• 12mm thickness: Provides a predictable offset change to correct clearance or achieve a modest flush look without extreme wheel protrusion.
• Zinc open end acorn lug nuts: Included hardware offers greater seating surface and helps prevent lug stud damage during installation.
• Thread locker supplied: Fastening aids are included to secure the spacer and help maintain clamp load when mounted per instructions.

Who It's For

These spacers are aimed at owners of vehicles that use a 5x112 bolt pattern and a 66.56mm hub bore, notably newer Audi G-chassis models such as A4, S4, A5, S5, A6, S6, A7, S7 and A8 Quattro from 2019 onward. They suit enthusiasts who want a lightweight, machined spacer that keeps a near-stock driving feel while improving wheel fitment or stance.

Those needing larger offsets, extreme track use, or who expect repeated heavy impacts should look for thicker spacers or specialized track hardware; also avoid models incompatible with the listed bolt pattern or hub bore. Installers who rely on impact guns should not use them here and should follow the cold forged steel lug and thread locker guidance supplied.

Pros & Cons
