Vossen RS74-42 x Champion Motorsport Forged Monoblock Wheel ET42

The Vossen x Champion Motorsport RS74 is a premium forged monoblock wheel engineered specifically for Porsche enthusiasts. Born from a collaboration between Vossen Wheels and Champion Motorsport — a celebrated name in global Porsche racing — the RS74 delivers an uncompromising combination of lightweight construction, aggressive concavity, and race-inspired aesthetics. The -42 designation (ET42) refers to the wheel's offset specification.

Constructed from aerospace-grade 6061-T6 aluminum, each RS74 wheel begins as a proprietary forging and is precision-machined through Vossen's exclusive six-step manufacturing process. Fitment accuracy is achieved by measuring over 100 data points per vehicle application, with CAD models validated using Finite Element Analysis (FEA) to maximize concavity while ensuring SAE and TUV compliance.

Key Features:

• Forged aerospace-grade 6061-T6 aluminum monoblock construction
• Classic Y-spoke design engineered for strength and reduced weight
• Available in centerlock and standard 5-lug fitments
• Exposed centering pins — a signature RS74 styling element enabling deeper spoke cuts
• Proprietary forging allows 8.5" width with concavity equivalent to a 12.5" wide wheel
• FEA-optimized weight-reducing pockets milled into the back pad
• Inboard lip engraved with wheel specifications, serial number, and personalized note
• Color-matched wheel weights and cap finish options (polished, brushed, or color-matched with red 'V' shield)
• Available in Vossen's full range of solid and transparent finish options
• Industry-leading 5-year workmanship warranty and lifetime structural warranty

The RS74 is available in 20" and 21" diameters and can be configured across Vossen's extensive palette of solid and transparent color finishes. Each wheel is individually inspected at every stage of production, with runout tolerance verified prior to shipment. The RS74-42 represents the pinnacle of Porsche-specific forged wheel engineering, combining motorsport heritage with meticulous craftsmanship.
