The BBS PFS hub centering ring is a wheel centric adapter with an 82mm outer diameter and a 70mm inner bore made to locate BBS wheels on Saab and Cadillac CTS applications requiring that hub size. It promotes proper wheel-to-hub alignment to reduce vibration and uneven wear, serving as a straightforward solution when aftermarket wheels or spacers need a matched center bore for secure, balanced installation.
