BBS FI-R

20x9 +52 / 20x12 +44 | Centerlock | Diamond Black

Overview

The BBS FI-R is a precision-engineered, forged wheel designed for Porsche enthusiasts who demand uncompromising performance and style. Tailored specifically for the 2019–2024 Porsche 911 (991) GT3 3.8L, this wheel blends lightweight construction with motorsport-grade durability, making it ideal for spirited driving and track use. The centerlock mounting system underscores its racing pedigree, offering quick-change capability favored in professional motorsport environments.

Finished in a sleek Diamond Black, the FI-R’s design language combines aggressive concavity with clean, purposeful spoke geometry. This visual appeal is rooted in BBS’s rich motorsport heritage, where form follows function to optimize both aesthetics and performance. The staggered setup enhances the car’s stance, with a wider rear wheel delivering an aggressive, planted look that complements the Porsche’s dynamic character.

This specific staggered configuration—with a 20x9 +52 front and 20x12 +44 rear—provides an ideal balance between sharp steering response and maximum rear traction. The centerlock system not only reduces unsprung weight but also simplifies wheel changes, making this setup highly desirable for enthusiasts who appreciate both style and track-ready functionality.

Design & Construction

The FI-R features a striking multi-spoke design that emphasizes both strength and lightweight performance. Its concave profile enhances visual depth while maintaining structural rigidity, a hallmark of BBS’s forged monoblock manufacturing process. Crafted from high-grade forged aluminum, these wheels offer exceptional durability and reduced rotational mass, directly benefiting handling and acceleration.

The Diamond Black finish is expertly applied to ensure a smooth, matte-like surface that resists corrosion and wear, maintaining its aggressive appearance over time. The centerlock mounting system reflects BBS’s motorsport roots, utilizing a single central nut for rapid wheel changes and improved hub stiffness. This design not only reduces unsprung weight but also contributes to the wheel’s precise fitment and performance on track and street alike.

What's Included

Fitment Notes

This staggered setup features a wider rear wheel for increased traction and an aggressive stance, which means front-to-rear tire rotation is not possible. The centerlock mounting requires a compatible hub system specific to Porsche GT3 models. Confirm hub bore and caliper clearance for your specific vehicle. This listing is for a full set of 4 wheels only.
