CNC Hexagonal Nut Kit for BBS RT075 wheels

The MG-line Hexagonal Nut Kit CNC is developed specifically for compatible BBS RT075 wheel centers.

A dedicated MG-line adapter is used to mount and position the hexagonal nut correctly within this wheel configuration. The system therefore does not rely on the direct 58 mm / 71 mm threaded fitment used by selected other BBS applications.

The exposed CNC-machined surface gives the center a precise, technical character while the traditional hexagonal form complements the classic BBS wheel design.

Key features

A distinctive classic wheel-center upgrade

A distinctive classic wheel-center upgrade

The MG-line Hexagonal Nut gives the wheel center a stronger and more distinctive character while preserving the classic motorsport-inspired shape associated with traditional multi-piece and tuning wheels. It works as a visual focal point that can completely change the appearance of the finished wheel.

Precision-machined construction

Precision-machined construction

Each MG-line Hexagonal Nut is precisely machined to achieve clean geometry, sharp edges and a high-quality fit. The substantial hexagonal form creates a solid technical appearance that works particularly well with classic BBS and period-inspired wheel designs.

Raw CNC machine finish

Raw CNC machine finish

The CNC Machine Finish leaves the machined surface visible, highlighting the geometry and manufacturing character of the component. The result is a clean, technical appearance with a raw aluminum-style look that works especially well on motorsport, OEM+ and classic builds.

Fitment designed around the original wheel center

Fitment designed around the original wheel center

Each Hexagonal Nut configuration is designed around the mounting system of the compatible wheel. Depending on the application, the nut uses the original threaded wheel center or a dedicated MG-line mounting adapter prepared specifically for the wheel geometry.

Why choose the CNC Hexagonal Nut Kit for BBS RT075?

The BBS RT075 combines classic wheel proportions with a distinctive center area. The CNC Hexagonal Nut makes this area a stronger visual feature and adds a purposeful mechanical detail that suits period-inspired and OEM+ builds.

What’s Included
Visual overview of the components included in the set.

Visual overview of the components included in the set.

One complete MG-line Hexagonal Nut set includes four hexagonal wheel-center nuts together with the dedicated MG-line mounting adapters required for four compatible wheels.

The adapter system is developed specifically for the intended wheel-center geometry and allows the Hexagonal Nut to be positioned correctly without relying on a direct threaded mounting interface.

The nuts and corresponding mounting components are supplied as a complete wheel-center solution.
Installation
This Hexagonal Nut configuration uses a dedicated MG-line mounting adapter developed for the compatible wheel center.

The adapter is installed according to the supplied configuration and positions the Hexagonal Nut correctly within the wheel center. This version does not use the direct 58 mm / 71 mm threaded installation used on selected BBS applications.

Always check that the mounting components seat correctly before final installation.
MG Hexagonal Nuts – Frequently Asked Questions
How is the Hexagonal Nut installed on BBS RT075 wheels?

The BBS RT075 version uses a dedicated MG-line mounting adapter rather than a direct threaded wheel-center connection.

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.
