Coilover Systems

Coilovers are used in double wishbone suspension systems, and are often a component of MacPherson struts. abbreviation of “coil-over shock absorber”

Coilover Benefit: Adjustment

  • Lower the vehicle’s centre of gravity
  • Adjust the ride height
  • Increase the roll stiffness of the vehicle
  • Reduce weight transfer in direction change
  • Adjust camber and caster angles (if compatible with adjustable top mounts)

This high degree of adjustment is what gives coilovers an advantage over typical MacPherson struts.

Typical Modes of Adjustment

  • Roll stiffness (Spring rate)
  • Ride height (threading or seating)
  • Compression and rebound (dampers)
  • Camber and caster (top mounts)

CorteX Coilovers, Optimized for Mustangs

  • Adequate bump travel at the lowered right height
  • Optimized the valving and spring rates
  • Minimized noise, vibration and harshness (NVH)
  • Adaptable, 7 damper options for our rear coilover system
  • Durable, proven performance tested under extreme stresses

CorteX Coilover Types

For our “Street,” “Track,” and “Race” Coilover suspension system kits, we have taken the time to ensure they work perfectly for your application. They are available for Ford Mustangs and a variety of chassis, in double and single adjustable systems.

Durable, Bolt-on Suspension Upgrade

Since we build and race our products, CorteX Coilovers are proven durable and designed to be compatible with our Xtreme-Grip™ suspension components.


Street coilovers have spring rates and valving suitable for street driving with treaded tires.  Softer spring rates are required for both ride comfort and also to maximize the mechanical grip available from less than sticky race tires. On mustang with solid rear axles the motion ratio in bump is different than the motion ratio in roll. The further the springs and shock can be moved toward the tires the closer bump and roll motion ratios come to each other allowing a more harmonious balance.  

CorteX “Street” coilovers allow for softer spring rates with more roll resistance minimizing unsprung weight.

Well designed coilovers are better able to provide a compliant ride than separate dampers with coil spring mounted further inboard on the axle housing.

Track coilovers have spring rates and valving suitable for track driving with competition rated tires. Competition tires are generally have a tread rating of less than 100 but are typically DOT approved.  These tires can handling spring rates nearly as stiff as racing slicks although the car the utilize them may still be at full street weight and used for dual purpose. Our

CorteX “Track” coilover systems are primarily focused on performance rather than ride comfort or NVH.

Race coilovers are for dedicated race cars that are not street driven. Spring rates are optimized for racing slicks not hard street tires.

CorteX “Race” coilovers may only allow racing alignments with high camber angles and require lower ride heights be set for the vehicle.

The dampers may also need more frequent maintenance features that are intended to keep dirt away are not included since they increase friction ultimately affecting handling.

Spec Mustang coil overs are a track-use system that is specifically configured to meet the Spec Mustang SMG rules, including required spring rates and valving that comply with SCCA series rules.
