Steeda S550 Mustang 'Ultimate' IRS "Stop The Hop" Pack - Mach 1 / GT350
Our IRS 'Stop the Hop' Package addresses wheel hop issues notorious with the S550 chassis 2015-2023 Mustang. The Steeda IRS Subframe Bushing Support System helps with rear subframe deflection which is a direct cause of wheel hop. These bushing supports stiffen the rear subframe allowing the car to increase traction to the rear wheels. In conjunction with the bushing we also include our IRS Subframe Alignment Kit, which ensures your subframe is directly aligned to your chassis, and results in straight launches off the line. Even though the Mustang Mach 1 and Shelby GT350 do offer an improved subframe setup from the factory, make no mistake, our Steeda setup will markedly improve your package!
This "Ultimate" Stop the Hop pack is aimed for forced induction/ Supercharged cars or for drag strip focussed cars, when putting power down is the main aim! Our "street" pack is perfect for road cars or track day cars.
Our Steeda Vertical Links are far superior to the stock vertical links on your S550 Mustang. They feature billet steel bushing sleeves and spacers, providing less deflection than the rubber bushings in the stock links, without increasing NVH. The strength of the billet that the Steeda Vertical Links are made of will provide a more solid feel to your suspension and will not flex under load. The street pack version is the polybush equipped vertical links rather than the Delrin equipped links from the "Ultimate" stop the hop pack, which is more suited to supercharged or drag focussed cars.
Our Steeda Mustang IRS Subframe Support Braces tie this Handling package together. These quality 4120 chrome moly steel braces are engineered to connect 3 very important points on the S550 chassis. The result of this solid connection is added rigidity that lacks in the rear of the 2015-2023 Mustang. By stiffening the connections of the rear of the chassis, this one component is able to limit IRS subframe movement, reduce wheel hop, and improve handling during cornering.
Our Steeda Adjustable Rear Toe Links improve the handling characteristics and improve your vehicle's overall handling response. These toe links have a large range of adjustability and adjustments can be made while they're installed on the car.
