Sporting Variety

The entry-level option is the RC-Design RC27, sized 8.0×18 ET15 with 225/60 R18 tires. Its timeless double-spoke design is available in Gloss Black and Crystal Silver, offering a durable and refined look for everyday use.

In the 19-inch segment, four distinctive designs are available – all in 8.5×19 ET26 with 245/50 R19 tires.
The RC-Design RC34 and RC36 feature a dynamic Y-spoke layout that adds a sporty accent to the vehicle. Both carry full ECE approval, just like the entire lineup. The Brock B41 and B43 are also available in 19 inches and bring more angular or technical styling options – ideal for drivers looking to enhance the factory look with subtle individuality.

For a bolder visual statement, the Brock B41 in 20 inches offers a powerful staggered setup: 9.0×20 ET24 / 255/45 R20 at the front and 10.5×20 ET44 / 285/40 R20 at the rear. Available in Gloss Black, Gloss Black Full Polished, and Ferric Grey, the B41 strikes a confident balance between sportiness and elegance.

The most striking fitment is the Brock B43 in 21 inches: 9.0×21 ET24 / 255/40 R21 at the front and 10.5×21 ET44 / 285/35 R21 at the rear. Finishes include Gloss Black, Gloss Black Full Polished, and Cosmic Grey Matt – ideal for those aiming for a high-impact upgrade with certified performance.
