CorteX Stage 2 Suspension System - 2015-2026 Ford Mustang S550 & S650
Take your 2015-2026 Ford Mustang suspension beyond a traditional spring-and-sway-bar setup with the CorteX Racing Stage 2 Suspension System. Building on the chassis and geometry improvements of Stage 1, Stage 2 adds the CorteX Xtreme-Grip Street Coil-Over System for greater ride height control, damping adjustability, and overall suspension precision.
The package is designed to reduce factory suspension compliance, maintain more consistent geometry under load, and give the driver greater control over how the car responds during aggressive street driving and track use. By combining adjustable coil-overs with upgraded sway bars, end links, toe links, vertical links, and mono-ball components, Stage 2 delivers a more planted, responsive, and confidence-inspiring Mustang chassis.
Features
- Complete Stage 2 suspension package for 2015-2026 Mustang S550 and S650 applications
- Designed for performance street and track use
- Adds fully adjustable CorteX Xtreme-Grip Street Coil-Overs
- Provides adjustable ride height
- Koni-based dampers with adjustable rebound
- Reduces factory suspension compliance and deflection
- Improves suspension geometry control under load
- Increases chassis response and feedback
- Provides greater alignment and handling adjustability
- Creates a more planted and predictable chassis during aggressive driving
CorteX Xtreme-Grip Street Coil-Over System
At the center of the Stage 2 package is the CorteX Xtreme-Grip Street Coil-Over System. This replaces a conventional lowering spring setup with a fully adjustable suspension solution that gives the driver greater control over ride height and damping characteristics.
- Adjustable ride height for precise stance and suspension setup
- Koni-based dampers with adjustable rebound
- Allows suspension response to be fine-tuned for street or track use
- Coil-over design improves chassis responsiveness
- Maintains street-friendly performance while adding greater control
Eibach Adjustable Sway Bars
Eibach adjustable sway bars increase roll stiffness and allow the front-to-rear balance of the chassis to be fine-tuned. This helps reduce body roll and gives the driver more control over handling balance.
- Adjustable stiffness
- Reduces body roll during aggressive cornering
- Improves chassis stability
- Allows front-to-rear balance adjustments
CorteX End-Link Kit
The CorteX End-Link Kit improves how effectively the sway bars transfer load into the suspension by reducing the compliance found in factory-style end links.
- Reduces unwanted end-link deflection
- Improves sway bar engagement
- Provides more consistent suspension response
- Improves feedback during aggressive driving
CorteX Toe Links
CorteX toe links help maintain rear wheel alignment under acceleration and cornering loads. By reducing unwanted toe changes, they contribute to a more stable and predictable rear suspension.
- Helps prevent unwanted rear toe change under load
- Improves rear-end stability
- Improves predictability during cornering and acceleration
- Provides greater durability than factory stamped components
CorteX Vertical Links
CorteX vertical links increase rear suspension stiffness and reduce deflection in critical mounting points, helping the suspension maintain more consistent geometry during performance driving.
- Reduces deflection from factory rubber bushings
- Improves suspension response
- Improves chassis control
- Helps maintain alignment under aggressive driving conditions
CorteX Mono-Ball Kit
The CorteX Mono-Ball Kit replaces compliant factory rubber bushings with precision spherical bearings. This significantly reduces suspension movement that does not contribute to wheel travel, improving steering feedback and chassis accuracy.
- Precision spherical bearing construction
- Dramatically reduces suspension deflection
- Improves steering feedback
- Improves chassis precision
- Provides motorsport-level suspension articulation and control
Designed for Street & Track Use
The Stage 2 system is intended for Mustang owners who want a significant increase in handling performance and adjustability without moving directly into a dedicated race-only suspension. Its combination of coil-over ride height adjustment, rebound tuning, upgraded chassis links, and reduced bushing compliance makes it well suited for spirited street driving, canyon roads, track days, and other performance applications.
