Steeda 'Stop the Hop' Ultimate Street Kit (555-2129-7GPP) - 2024-2026 Mustang w/ Brembo
Upgrade your 2024-2026 Ford Mustang with the Steeda 'Stop the Hop' Ultimate Street Kit and experience improved traction, sharper handling, and dramatically reduced wheel hop. Specifically engineered for S650 Mustang models equipped with the factory Brembo Brake Package, this comprehensive IRS suspension package reinforces the rear suspension while maintaining excellent street manners with virtually no additional noise, vibration, or harshness (NVH).
The factory independent rear suspension allows unwanted movement through compliant rubber bushings, leading to wheel hop, inconsistent launches, and reduced handling precision. Steeda's Ultimate Street Kit addresses these shortcomings by strengthening the IRS subframe, properly aligning the rear cradle, reducing suspension deflection, and improving rear toe control. The result is a more planted Mustang that launches straighter, corners with greater confidence, and delivers improved overall driving performance.
