Steeda Mustang 'Stop the Hop' Street Ultimate Kit (2015-2023)
Give your 2015+ Mustang the proven performance of Steeda manufactured suspension parts. This Ultimate IRS 'Stop the Hop' Package for your 2015+ Mustang GT, EcoBoost, or V6 is designed to provide increased traction, stiffen the IRS subframe, reduce wheel hop, and improve overall handling characteristics.
The Steeda IRS Subframe Bushing Support System helps with rear subframe deflection, a direct cause of wheel hop, while the included IRS Subframe Alignment Kit ensures your subframe is directly aligned to your chassis for straight launches off the line. The Steeda Vertical Links feature billet steel bushing sleeves and spacers for less deflection than the stock rubber bushings without increasing NVH. The IRS Subframe Support Braces are quality 4130 chrome moly steel pieces that connect three key points on the S550 chassis, adding rigidity that limits subframe movement, reduces wheel hop, and improves handling during cornering. Finally, the Adjustable Rear Toe Links improve overall handling response with a large range of on-car adjustability.
Note: Steeda IRS Subframe Support Braces will not fit convertible models. Will not fit 2024+ Mustangs equipped with Brembo brakes.
