Steeda 'Stop the Hop' Drag Ultimate Kit (555-2129-D-7GPP) - 2024-2026 Mustang w/ Brembo
Take your 2024-2026 Ford Mustang with the factory Brembo Brake Package to the next level at the drag strip with the Steeda 'Stop the Hop' Drag Ultimate Kit. Purpose-built for S650 Mustang GT, EcoBoost, and Dark Horse models equipped with Brembo brakes, this complete IRS suspension package eliminates wheel hop, minimizes suspension deflection, and maximizes traction for harder launches and quicker elapsed times.
The factory IRS allows excessive movement through soft rubber bushings, causing wheel hop and inconsistent launches that rob your Mustang of valuable performance. Steeda's Drag Ultimate Kit reinforces the IRS subframe, eliminates unwanted compliance, improves suspension geometry, and replaces key rubber bushings with precision-engineered performance components. The result is a more stable rear suspension that puts more power to the pavement, improves 60-foot times, and gives you the confidence to launch harder run after run.
