Fitment Notes

• Ford Mustang fitment is confirmed for EcoBoost models equipped with the Performance Package only - non-Performance Package Mustang EcoBoost and V8 GT/GT350/Shelby variants are not confirmed for this SKU.
• Hub bore is 72.6mm; hub-centric rings may be required depending on the specific vehicle's hub bore diameter - verify before installation.
• Offset is +45mm (backspacing: 6.03 in, frontspacing: 2.48 in) - verify clearance with your specific brake and suspension setup before installing, particularly on WRX STI models with Brembo calipers.
• This is the Hyper Silver finish variant. For the Gunmetal finish in this same size, bolt pattern, and offset, see part number 442-875-6545GM.
• The EKM3 is available in 17 and 18 inch diameters. For the 17x7 version in 5x114.3, see 442-770-6545HS.
• This wheel is sold individually; a set of four (4) is required for complete vehicle fitment.
• A center cap is included with purchase.

Features

• 10-spoke mesh design in a Hyper Silver finish - a premium two-tone machined and painted aesthetic that provides a more upscale appearance compared to standard silver or matte finishes, suited to refined sport sedan and muscle car builds alike.
• Single bolt pattern (5x114.3) - unlike dual-drilled SKUs, this wheel is purpose-built for 5x114.3 platforms, ensuring clean hole placement and a properly engineered spoke structure optimized for this specific bolt circle.
• The 18x7.5 size at +45mm offset delivers a wider tire contact patch than narrower 18-inch options while the conservative offset maintains flush-fitting, OEM-adjacent stance geometry on the WRX and Mustang platforms.
• Exposed lug design integrates the lug seat directly into the wheel face, contributing to the EKM3's clean, sport-oriented aesthetic consistent across the Performance Series lineup.
• Engineered and tested to Enkei's proprietary Spec-E standard, which exceeds JWL requirements by demanding a higher drop point in the impact test and 20% more cycles in both rotary bending fatigue and dynamic radial fatigue testing.
• One-piece cast alloy construction provides a consistent, balanced wheel structure with no multi-piece joint variance and predictable performance across all four wheels in a set.
• Available in Hyper Silver and Gunmetal in 5x114.3 at this size, as well as a range of other bolt patterns and offsets across the EKM3 lineup including 5x100, 5x112, and 5x110 configurations.
• Load rating of 1,522 lbs per wheel provides ample capacity for the sport sedan and sport coupe platforms this configuration targets.
• Backed by Enkei's Lifetime Structural Warranty and 1-Year Finish Warranty through authorized dealers.

Product Description

The Enkei EKM3 (442-875-6545HS) is an 18x7.5 Performance Series wheel in a Hyper Silver finish, drilled for the 5x114.3 bolt pattern at +45mm offset. The EKM3's 10-spoke mesh design and Hyper Silver finish represent a step above the standard silver and matte options in the Enkei catalog - the machined accent work in the Hyper Silver treatment creates a premium, multi-tone appearance well suited to the sport sedan character of the Subaru WRX and WRX STI platforms, as well as the more muscular proportions of the Ford Mustang EcoBoost with Performance Package. Confirmed fitments span the 2015-2025 WRX, three generations of WRX STI (2005-2021), and the 2015+ Mustang EcoBoost PP, giving this single SKU meaningful coverage across both Japanese all-wheel-drive sport sedans and American rear-wheel-drive sport coupes.

The 5x114.3 single-drill configuration - unlike the dual-drilled EDR9 and J10 SKUs - means the wheel's bolt hole geometry is optimized entirely for this one bolt circle, without the structural compromise of secondary holes. At 23.2 lbs per wheel and with a 1,522 lb load rating, the one-piece cast alloy construction meets Enkei's Spec-E testing standard, which demands a higher impact drop point and 20% more fatigue test cycles than mandatory JWL minimums. The +45mm offset and 6.03-inch backspacing position the wheel face conservatively inboard, making this a flush-fitting, daily-driver-friendly choice that doesn't require fender modifications on standard-height WRX or Mustang suspension configurations.

This wheel is sold individually and a set of four is required for complete fitment. Hub-centric rings and lug nuts are not included - verify hub bore compatibility at 72.6mm before purchase. A center cap is included. Mustang fitment is confirmed for EcoBoost models with the Performance Package only; non-PP and V8 variants are not confirmed for this SKU. For the Gunmetal finish in this same size and configuration, see 442-875-6545GM. For the 17x7 Hyper Silver version, see 442-770-6545HS.
