Enkei 460-885-6648SP PF01 Racing 18x8.5 Silver 5x114.3 +48mm Subaru WRX/STI

Vehicle Fitment

• 2015-2017 Subaru WRX (Base, Premium, Limited, AWD, 2.0L H4 Turbo)
• 2005-2007 Subaru WRX STI (AWD, 2.5L H4 Turbo)
• 2008-2014 Subaru WRX STI (AWD, 2.5L H4 Turbo)
• 2015-2017 Subaru WRX STI (Base, Limited, Series.Gray, AWD, 2.5L H4 Turbo)

Fitment Notes

• Fitment is confirmed for 2015-2017 WRX and 2005-2017 STI generations only. The 2018-2024 WRX and 2018-2021 STI share the same 5x114.3 bolt pattern but are not confirmed for this specific SKU - verify independently before purchasing for those model years.
• Hub bore is 75mm - larger than the 72.6mm bore found on most Enkei Performance Series wheels. Hub-centric rings may be required for vehicles with a hub bore smaller than 75mm. Verify your vehicle's hub bore before installation.
• Offset is +48mm (backspacing: 6.64 in) - this is the deepest-inboard offset option among the 18x8.5 PF01 5x114.3 variants. Verify clearance with your specific brake and suspension setup, particularly on STI models with Brembo calipers.
• This is the Silver finish variant. For the Matte Black version in this same size and offset, see part number 460-885-6648BK.
• The +48mm offset on this 18x8.5 wheel is noted by owners to closely match the OEM fitment geometry of the VA-chassis WRX/STI and also meets SCCA Street Class offset rules - useful for club racing applications.
• This wheel is sold individually; a set of four (4) is required for complete vehicle fitment.
• A center cap and valve stem are included with purchase.

Features

• Built using Enkei's MAT (Most Advanced Technology) flow-forming process, which combines a cast aluminum center with a rim-spinning operation that pressure-shapes and densifies the barrel section, producing a wheel that is significantly lighter than conventional casting alone while maintaining equivalent or superior structural strength.
• Ultra-lightweight at 18.5 lbs per wheel - within the performance range typically associated with forged wheels, and substantially lighter than standard cast alloy wheels of equivalent diameter and width.
• Split 5-spoke design is derived directly from Enkei's motorsport racing wheel program, with subtle dimensional edge detailing along each spoke face that adds visual depth while contributing to lateral stiffness under cornering loads.
• Roulette pattern grooved into the inside of the rim barrel reduces the slippage ratio between tire and wheel during extreme acceleration and deceleration, maintaining optimal tire bead seating and wheel assembly performance under motorsport-level stress.
• Large brake caliper clearance is built into the spoke architecture and 18-inch diameter, making the PF01 compatible with upgraded big brake kits and high-performance factory Brembo setups on the WRX and STI platforms.
• The +48mm offset / 18x8.5 combination closely replicates the OEM wheel fitment geometry of the VA-chassis WRX STI, making this one of the most direct OEM-replacement-geometry options in the PF01 lineup for that platform.
• Engineered to meet Enkei's Spec-E testing 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.
• Backed by Enkei's Lifetime Structural Warranty and 1-Year Finish Warranty through authorized dealers.

Product Description

The Enkei PF01 (460-885-6648SP) is an 18x8.5 Racing Series wheel in silver, drilled for the 5x114.3 bolt pattern at +48mm offset. The +48mm offset combined with the 8.5-inch width makes this one of the most precisely tuned PF01 SKUs for the VA-chassis Subaru WRX and WRX STI platforms - owner reviews consistently note that the 18x8.5 / +48mm geometry closely replicates the OEM wheel fitment of the STI, providing a direct drop-in upgrade in terms of stance and clearance. It also satisfies SCCA Street Class offset regulations for competitive autocross and club racing applications, making it a practical dual-purpose wheel for both street and entry-level motorsport use.

The PF01 is built using Enkei's MAT flow-forming process - a rim-spinning operation that pressure-densifies the barrel section of the wheel after the center is cast, dramatically improving the material properties of the rim without the full cost of a forged wheel. The result is an actual weight of 18.5 lbs per wheel, which is well within the performance range typically reserved for forged alternatives at two to three times the price. The split 5-spoke design provides lateral stiffness under cornering and includes the motorsport-derived roulette groove inside the rim barrel, which helps maintain the tire bead seat and minimize slippage under extreme acceleration and braking. Large spoke clearance ensures compatibility with the Brembo calipers fitted to the WRX STI across all confirmed fitment years.

Confirmed fitment covers the 2015-2017 WRX, 2005-2007 STI, 2008-2014 STI, and 2015-2017 STI per the OAKOS authorized dealer fitment list. Buyers with 2018-2021 STI or 2018-2024 WRX should verify fitment independently before purchasing, as those years are not confirmed for this SKU. The wheel is sold individually and a center cap and valve stem are included. Hub-centric rings and lug nuts are not included - verify hub bore compatibility at 75mm for your specific vehicle. For the Matte Black version, see 460-885-6648BK. For the 5x100 / +48mm version designed for the BRZ and GR86, see 460-885-8048SP.
