Steeda Mustang Ultimate IRS 'Stop the Hop' Package (15-18 All)
Give your 2015-2017 Mustang the proven performance of Steeda manufactured suspension parts. This Steeda Mustang Ultimate IRS 'Stop the Hop' Package for your 2015-2017 Mustang GT, EcoBoost, or V6 is designed to provide increased traction, stiffen the IRS subframe, reduce wheel hop, and improve overall handling characteristics.
Steeda IRS 'Stop the Hop' Package addresses wheel hop issues notorious with the new 2015 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.
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.
Steeda Mustang IRS Subframe Support Braces tie this Steeda Stage 3 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 2015-2017 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.
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.
