Fitment Notes

• This listing is for a single wheel. Sold individually.
• Wheel size: 18x8 in. | Bolt pattern: 5x120mm | Offset: +15mm | Backspace: 5.10 in. | Frontspacing: 3.91 in. | Center bore: 78.1mm
• This wheel is used as a front drag wheel on the listed 5x120mm GM platforms. It provides a slightly wider front tire footprint compared to the 18x5 in. front runner option (PN S1558C022N23), making it appropriate for builds that benefit from a wider front stance while still optimizing rotating mass versus a street-width wheel.
• 2016+ CAMARO ZL1 (6th Gen) with factory Brembo 15.35 in. 6-piston front brakes: A 13mm spacer is required for brake clearance.
• CAMARO ZL1 1LE and models equipped with the BCD Copper Free Brake Kit: This 18 in. wheel is NOT compatible - a 19 in. front wheel is required for these configurations.
• Center bore is 78.1mm. The listed vehicles have smaller factory hub bores - hub-centric rings are required for all applications. Rings must be sourced separately.
• Requires 60-degree conical seat lug nuts (M14x1.5 for most GM applications). Factory lug nuts are not compatible. Weld-branded lug nut kits are available separately.
• True Directional: No - mounts in any rotational orientation.

Features

• 18x8 in. drag front wheel for the 5x120mm GM performance platform - wider than a front runner but lighter and lower-inertia than street-width front wheels, providing a balanced drag strip front end setup
• 1-piece Rotary Forged (Flow Formed) monoblock construction with bead knurling - Rotary Forging densifies the aluminum barrel for near-forged wall strength; bead knurling improves tire bead retention under drag launch loads without requiring a full beadlock assembly
• Ventura S155 split-spoke design delivers a bold, race-derived aesthetic purpose-built for the GM muscle car platforms on this bolt pattern
• Gloss black field with precision-milled spoke windows for a high-contrast finish
• 5-spoke split-spoke design with exposed lug pockets
• Non-Beadlock - lightweight and low maintenance for street and strip applications
• 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 S15588022P15 is an 18x8 in. Ventura Drag S155 Rotary Forged monoblock wheel in Gloss Black with Milled Spoke Windows, built for the 5x120mm GM performance platform covering the Pontiac GTO, Pontiac G8 GT, Cadillac CTS-V (Gen 2), Chevrolet SS Sedan, 5th and 6th Generation Chevrolet Camaro SS/1LE/ZL1, and the Chevrolet Corvette C6 Base and Z51. As a front drag wheel, the 18x8 occupies a specific role in the drag setup hierarchy for these platforms: it provides a wider front tire section than the ultra-narrow 18x5 front runner (also available in the S155 series as PN S1558C022N23), while still remaining significantly lighter and lower in rotational inertia than a full street-width front wheel. This makes it the preferred front wheel for builds that want a meaningful drag strip advantage without the extreme stance of a fully dedicated front runner configuration.

The Ventura Drag S155 construction applies Weld's Rotary Forging (Flow Forming) process to the barrel section of the aluminum monoblock, densifying the grain structure for near-forged barrel strength at reduced weight. Bead knurling on the barrel improves tire bead retention under the load spikes of hard drag launches. At +15mm offset and 5.10 in. backspace, this wheel is correctly positioned within the front wheel arch of all listed applications, clearing the factory brake systems on standard SS and CTS-V configurations - with the noted exception of the 6th Gen Camaro ZL1's 15.35 in. Brembo 6-piston setup, which requires a 13mm spacer.

Hub-centric rings are required for all listed applications - this wheel's 78.1mm center bore is larger than the factory hub bores on all listed GM platforms. Requires 60-degree conical seat lug nuts - factory GM lug nuts are not compatible. The Camaro ZL1 1LE and BCD Copper Free Brake Kit-equipped models require a 19 in. front wheel and are not compatible with this 18 in. wheel. Sold as a single wheel. Made in Kansas City, Missouri, USA.
