Description

The fifteen52 Vertex RSR is a lightweight mesh wheel designed for enthusiasts seeking a perfect balance of performance, style, and durability. Originally introduced as a forged wheel, the Vertex RSR is now available in a flow-formed construction that offers enhanced strength while reducing weight. Its split 7-spoke design features scalloped spokes that optimize rigidity and reduce unsprung mass, making it ideal for both street and track use.

Specifically engineered for Subaru WRX models from 2015 to 2024 and STI models from 2011 to 2021, the Vertex RSR delivers excellent brake clearance and aggressive styling. Available in 18×9.5 size with a 5×114.3 bolt pattern and 38mm offset, this wheel fits perfectly on these vehicles, enhancing handling and aesthetics without compromising reliability.

Key Features

The Vertex RSR combines advanced engineering with practical design elements to meet the demands of performance drivers. Key features include:

• Flow-formed A356-T6 aluminum construction for a lightweight yet durable wheel
• Split 7-spoke mesh design with scalloped spokes to reduce weight and increase strength
• Multiple face profiles offering maximum brake caliper clearance and lip size options
• Variable depth lug bowls to minimize weight without sacrificing structural integrity
• Reinforced outer lip and oversized lug pockets for track-ready durability
• Ball cut scalloped spokes for enhanced aesthetics and reduced rotational mass
• Chassis-targeted fitment ensuring precise fit and optimal performance
• Tested to SAE J2530 standards with TUV certification where applicable
• Available in new colors with options for square and staggered fitments

Construction & Design

The Vertex RSR wheels are crafted using flow-formed A356-T6 aluminum, a process that combines the strength of forged wheels with the cost-effectiveness of casting. This method involves casting the wheel and then applying pressure to the barrel while spinning, which aligns the grain structure of the aluminum for improved strength and reduced weight.

The split 7-spoke design features scalloped edges that reduce material where it’s not needed, lowering overall weight while maintaining rigidity. The reinforced outer lip and oversized lug pockets provide additional durability, especially under the stresses of aggressive driving and track conditions. Multiple face profiles allow for customization in brake clearance and lip size, accommodating a variety of brake setups.

Installation & Fitment

The fifteen52 Vertex RSR wheels are designed for direct fitment on Subaru WRX models from 2015 through 2024 and STI models from 2011 through 2021 with a 5×114.3 bolt pattern. The 18×9.5 size with a 38mm offset ensures proper clearance for factory and many aftermarket brake systems without requiring modifications.

Installation is straightforward with standard lug nuts and hardware. No special adapters or spacers are typically needed, allowing for a clean, factory-like fit. Always verify fitment with your specific vehicle and brake setup before installation.

What’s Included

• One fifteen52 Vertex RSR wheel in 18×9.5 size with 5×114.3 bolt pattern and 38mm offset
• One new aluminum RSR center cap (70mm diameter for 5×114.3 specifications)
