The Mirror Polished version is carefully finished to create a bright, reflective surface that gives the wheel center a more refined and premium appearance.

MG Hexagonal Nuts – Frequently Asked Questions
Which thread size should I choose for my BBS RC 300 wheels?

Choose either 58 mm or 71 mm according to the original wheel-center thread. If you are unsure, confirm the original configuration before ordering.

Are all MG Hexagonal Nuts mounted in the same way?

No. The mounting system depends on the wheel application. Selected BBS models use direct 58 mm or 71 mm thread configurations, Lenso BSX uses its compatible internal wheel-center thread, while other applications use a dedicated MG-line mounting adapter.

Which products use the 58 mm or 71 mm thread options?

Compatible BBS RC 300 Series, BBS RS / RSII / RC and BBS RC 041 / BMW Style 29 applications are available with 58 mm and 71 mm thread configurations. The correct option must correspond with the original threaded wheel center.

Which products use a dedicated mounting adapter?

BBS RC 090 / BMW Style 5, BBS Styling 101 and BBS RT075 configurations use dedicated mounting adapters. The Mirror Polished BBS RF Series version also uses an adapter-based mounting solution.

What is the difference between CNC Machine Finish and Mirror Polished?

CNC Machine Finish retains the visible machined surface for a more technical and raw appearance. Mirror Polished versions are further finished to achieve a smooth, highly reflective surface with a more classic and premium character.

Do these nuts replace the way the wheel is attached to the vehicle?

No. MG-line Hexagonal Nuts are wheel-center components and do not replace the original wheel-to-hub mounting system.

Are these original BBS or Lenso products?

No. They are aftermarket products manufactured by MG-line and designed for compatible wheel applications. Wheel manufacturer and model names are used to identify compatibility.
