S550 Suspension Package

S550 Suspension Overhaul Package

The Vertex Motorsports S550 Suspension Overhaul Package is a comprehensive chassis and suspension upgrade designed to completely transform how your Mustang handles, responds, and puts power to the ground. This package addresses the factory S550’s known weak points—wheel hop, rear-end deflection, vague steering feel, and inconsistent alignment—resulting in a planted, predictable, and confidence-inspiring driving experience.

At the core of the package are performance coilovers, delivering improved ride control, sharper turn-in, and reduced body roll while maintaining street usability. Upgraded polyurethane bushings, cradle lockout, and lower control arm bushings eliminate unwanted movement in the rear suspension, dramatically improving traction and throttle response under load.

To further stabilize the IRS, this package includes IRS bracing, adjustable toe rods, toe link bearing kit, and adjustable camber links, allowing precise alignment control for aggressive street driving, track use, or drag-focused setups. A 2-point front subframe chassis brace ties the front end together, improving steering feedback and chassis rigidity during hard cornering and braking.

The package is completed with professional installation and a precision wheel and tire alignment, ensuring everything works together as a cohesive, dialed-in system.
