S650 Ford Mustang Wheels

The S650 supports 19-inch and 20-inch wheels as the standard diameters for street and performance builds. On a staggered setup, the most common configuration is 19x10 or 20x10 up front with a 19x11 or 20x11 out back. Square setups run 19x10 or 20x10 on all four corners. For track use, 19-inch setups are preferred for the unsprung weight advantage. All fitments on this page are verified for the full 2024-2026 S650 platform.

Yes. The S650 shares the same 5x114.3 bolt pattern, 70.6mm center bore, and compatible offset range as the S550. Verified fitments that worked on a 2015-2023 S550 translate directly to the 2024-2026 S650. The key difference is the Dark Horse with the Handling Package, which requires a 19-inch minimum diameter on all Dark Horse models.

All S650 Mustangs use a 5x114.3 bolt pattern; five lugs at a 114.3mm pitch circle diameter. This applies to every trim including the GT, EcoBoost, and Dark Horse. Lug hardware is M14x1.5, and the factory torque spec is 150 ft-lbs.

The S650 Mustang uses a 70.6mm center bore. Project 6GR wheels are machined to this exact measurement, making them a true hub-centric fitment. No centering rings or adapter hardware are required.

The Dark Horse Handling Package runs a factory front offset of +24mm on a 20x10.5 front wheel, which is the most aggressive front geometry on any production Mustang. This creates a wider and more planted front track width compared to the standard GT or base Dark Horse. The front fender extensions are fitted exclusively to this configuration. Project 6GR verifies fitment against the HP's specific front geometry and Brembo package as a separate configuration.

No. The Dark Horse's Brembo brakes feature a 6-piston front caliper with 390mm front rotors and requires a minimum 19-inch wheel diameter on all Dark Horse models regardless of trim or package. GT and EcoBoost models without the Performance Pack can run select 18-inch setups, but this is not applicable to any Dark Horse configuration.

Staggered runs a wider rear wheel than the front, typically 19x10 or 20x10 up front with 19x11 or 20x11 out back. It delivers a more aggressive visual stance and adds rear traction on high-power builds, but it does not allow front-to-rear tire rotation. Square runs the same size on all four corners, enabling tire rotation, reducing understeer, and keeping handling neutral under lateral load. Track and road course use consistently favors a square 19x10 setup on the S650.

Yes. Every S650 fitment on this page is verified for clearance with the Dark Horse Brembo's. No spacers, no modifications, and no changes to the brake hardware are required. If your car is running an aftermarket big brake kit, contact the team directly to confirm clearance for your specific application.

Spun Forged (flow formed) starts with a cast aluminum blank that is spun and formed under high pressure while heated. The process compresses the barrel material, producing a wheel that is lighter and structurally stronger than a conventional cast wheel. Monoblock Forged is machined entirely from a single 6061-T6 aluminum billet. Monoblock Forged is the higher-performance construction and carries a higher price point. Both are available across all verified S650 fitments.

Yes. Project 6GR wheels are designed to accept the factory Ford TPMS sensors that came on the S650 from the factory. No sensor replacement or additional hardware is required.

Yes. The verified offsets published on this page are compatible with common lowering spring and coilover configurations running a standard to moderate drop. For builds running an aggressive suspension drop, aftermarket fender work, or non-standard brake hardware, contact the team to confirm clearance before ordering.

Project 6GR wheels carry a lifetime structural warranty and a one-year finish warranty. The structural warranty covers manufacturing defects under normal use. Road hazards, improper tire sizing, unauthorized modifications, and damage from incorrect installation or maintenance are not covered. Full warranty terms are available at project6gr.com/warranty/.
