Modern clarity

The Brock B43 is available in several versions: as a 20-inch all-around option (8.5×20 ET24 with 255/45 R20), in a 21-inch all-around configuration, and as a staggered 21-inch combination with 9.0×21 ET26 on the front axle (255/40 R21) and 9.5×21 ET30 on the rear axle (275/40 R21). The applications are designed with ECE and ABE approval and, in conjunction with standard-compliant mounting and OE hub cap compatibility, enable a technically clean and precise fit. The clearly structured design blends harmoniously with the modern styling of the BMW iX3 and underscores its striking appearance.

The RC-Design RC36, a dynamically styled 10-spoke design, rounds out the portfolio. The 8.5×20 ET24 version with 255/45 R20 tires is ECE- and TTG-approved and is also designed for standard mounting and use with the OE hub cap. The precise lines blend harmoniously into the vehicle’s overall appearance and emphasize its modern character.

Both wheel models are available in Gloss Black and Full-Polished Gloss Black finishes, allowing for stylish coordination with different vehicle variants.

With the B43 and the RC36, Brock Alloy Wheels is expanding its range for the new BMW iX3 with precisely tailored wheel solutions—tailored to the vehicle architecture, standard tires, and verified technical requirements.
