Fitment Notes

• This listing is for a single wheel. Sold individually.
• Wheel size: 17x5 in. | Bolt pattern: 5x114.3mm (5x4.5 in.) | Offset: -21mm | Backspace: 2.18 in. | Center bore: 78.1mm
• FRONT ONLY. This is a narrow drag front runner wheel designed exclusively for the front axle on all listed applications. It is NOT intended for rear fitment.
• BRAKE CLEARANCE WARNING: This wheel will NOT clear 6-piston Brembo or larger front brake calipers. Excluded applications due to factory front brake incompatibility: 2015-2022 Shelby GT350 (all years) and 2020+ Shelby GT500 (S550). All other listed S550 Mustang trims (GT, V6, EcoBoost) are compatible.
• SFI 15.1 and 15.2 certified - approved for use at sanctioned drag racing events.
• Center bore is 78.1mm. Hub-centric rings may be required depending on your vehicle's hub bore. Verify before installation.
• Requires 60-degree conical seat lug nuts. Factory lug nuts may not be compatible with Weld's lug pocket design. Weld-branded lug nut kits are available separately and strongly recommended.
• The raised center cap design provides added axle clearance on applications with longer axle hardware.

Features

• 17x5 in. narrow drag front runner wheel - minimizes front-end rotating and unsprung mass on the listed Mustang, Nissan 350Z/370Z, and Toyota Supra MK4 drag platforms for maximum weight transfer, faster 60-foot times, and reduced elapsed times
• 1-piece Rotary Forged (Flow Formed) monoblock construction with inner and outer barrel knurling - bead knurling mechanically improves tire bead retention under hard launches without a full beadlock assembly
• SFI 15.1 and 15.2 certified - meets sanctioned drag racing safety standards for front runner wheel use
• Raised center cap design provides added axle clearance for the longer hub hardware on the listed platforms
• Gloss black field with precision-milled spoke windows and diamond-cut polished lip - the Ventura S155 split-spoke design delivers a visually distinct aesthetic from the Laguna S152 mesh-spoke, while sharing the same underlying construction and drag performance geometry
• 5-spoke split-spoke design with exposed lug pockets for a clean, lightweight visual profile
• 1,600 lb rated load capacity per wheel
• Non-Beadlock - lightweight and low maintenance for street and strip use at standard tire pressures
• True Directional: No - mounts in any rotational orientation
• Engineered using FEA (Finite Element Analysis) for optimal strength-to-weight ratio and minimum rotational moment of inertia
• Designed and manufactured in Kansas City, Missouri, USA

Product Description

The Weld Racing S1557C067N21 is a 17x5 in. Ventura Drag S155 Rotary Forged front runner wheel in Gloss Black with Milled Spoke Windows and Diamond Lip, built for the 5x114.3mm (5x4.5 in.) bolt pattern covering the FoxBody Mustang through S550 Mustang continuum, as well as the Nissan 350Z/370Z and Toyota Supra MK4. It is the Ventura S155 counterpart to the Laguna S152 S1527C067N21 front runner - sharing the identical 17x5 / -21mm / 2.18 in. BS / 78.1mm bore specification, load rating, and SFI certifications, but presenting Weld's distinct Ventura split-spoke design rather than the Laguna mesh-spoke profile. For builders choosing between the two, the decision is entirely aesthetic - both deliver the same front runner drag wheel performance geometry and construction on these platforms.

At 17x5 in. and just 17 lbs (consistent with S155 construction at this size), this wheel removes a significant quantity of rotating and unsprung mass from the front axle - the modification that produces the largest proportional improvement in drag strip weight transfer, 60-foot times, and elapsed times relative to almost any other hardware swap on a front-engine, rear-wheel-drive drag car. The Rotary Forging (Flow Forming) process densifies the aluminum barrel for near-forged wall strength, while the inner and outer barrel knurling mechanically interlocks with the tire bead under the sudden load spikes of hard drag launches, improving bead retention without the weight or maintenance overhead of a full beadlock assembly. SFI 15.1 and 15.2 certification makes this wheel legal at sanctioned drag racing events.

Important notes: this wheel will not clear 6-piston Brembo or larger front calipers - the Shelby GT350 (all S550 years) and 2020+ Shelby GT500 are specifically excluded. All other S550 Mustang trims, all S197 Mustangs, all SN95/New Edge Mustangs, FoxBody Mustangs, Nissan 350Z/370Z, and Toyota Supra MK4 are confirmed compatible front-position fits. Hub-centric rings may be required. Requires 60-degree conical seat lug nuts - factory lug nuts are not compatible. Sold as a single wheel. Made in Kansas City, Missouri, USA.
