Performance Redefined

That is what the Steeda Q500 Enforcer™ Edition is all about. We know that it's not just about who's the first one into a corner that matters, but who's the first one out that counts, so our engineers created a balanced performance package using our sophisticated Steeda G/Trac Suspension components. When you strap into a Steeda Q500 Enforcer™ Edition.....ignite the engine.....and challenge the road ahead, you'll know we just didn't cobble together a few performance parts and call it a day. This vehicle is built to the highest quality standards incorporating our proprietary performance parts that are designed, engineered, and manufactured under rigorous ISO 9001:2008 Compliant Standards. The Steeda Q500 Enforcer™ Edition is put through it's paces under the toughest conditions imaginable and the result is a muscular yet refined balanced performer that has no equal.

Argument Against Status Quo

Power means nothing without stability and control, the Steeda Q500 Enforcer™ Edition G-Trac Suspension and chassis modifications that have been strategically engineered into every Q500 Enforcer are designed to break the performance boundaries of the new S550 Mustang. The result is a level of performance that makes for an unbeatable combination on the street, racetrack or drag istrip – all without sacrifice.

Designed From Scratch. Pushed To The Limit.

For the Steeda Q500 Enforcer™ we have undertaken unprecedented measures focusing on dramatically enhancing its driving dynamics. We have developed the most comprehensive collection of suspension and chassis upgrades of any manufacturer in the market today – that when taken together, provide power and control on a master scale that is unmatched. With newly found impressive driving dynamics, the Steeda Q500 Enforcer™ provides a level of excitement and driving that delivers practically zero pitch and roll and a level of suspension refinement that has never been experienced in a production Mustang before.

Innovation & Speed Technology

The Steeda Engineering Team developed a proprietary Cold Air Intake system that incorporates an industry exclusive integrated billet aluminium velocity stack. This feature dramatically increases and stabilises the flow of cool incoming air to the engine and when combined with our performance engine calibrations, the results are nothing short of spectacular. From idle to redline, our Steeda special engine calibration starts where others left off – delivering a confident power that is rapid and responsive. Throttle response is immediate and predictable and when coupled with our exclusive suspension and chassis modifications, you have the perfect combination of control allowing for closer contact with the road ahead.

Aerodynamic Design

As speed increases, the air rapidly thins out – which is why attention to aerodynamics is so critical in a performance vehicle. Subtle, yet muscular in style, our Steeda aerodynamic changes are designed for function. From the Steeda lowering springs that provide the optimum height for aerodynamic and suspension performance, to the front fascia that provides minimum drag and the appropriate level of downforce (aiding the front tires to get more grip and providing reduce understeer tendencies), everything is done with the goal of maximising performance in mind.

Hand-built with exquisite attention to detail and uniquely serialised, the 2018-2023 STEEDA Q500 ENFORCER is built by Mustang Motorsport under licence by Steeda Performance Vehicles.

Steeda Q500 Enforcer™ Edition - The Iconic 5.0 Reborn

The Steeda Q500 Enforcer™ Edition was designed for hardcore, power-hungry performance enthusiasts who want the most Mustang muscle for their money, period. It starts with the 5.0-litre aluminium block V8 that’s a modern interpretation of the legendary Ford power plant. With a bevy of Steeda performance upgrades, this naturally-aspirated beast will churn out plenty of pure pony power to humble the competition. Power means nothing without control, so the Q500 precision-engineered suspension and chassis modifications keep the driver in command and deliver the level of performance that make it an unbeatable combination delivering pure driving excitement.

*All horsepower & torque ratings are estimates of engine power based on engineering prototypes, and laboratory tests under optimum conditions using a minimum of 93 octane Premium Fuel. Actual figures may vary. Supercharged horsepower ratings are quoted from Whipple Superchargers ( and are 775HP (Stage 1) or 825HP (Stage 2). All power ratings listed are calculated crankshaft ratings based on RWHP readings from a chassis dynamometer. NOTE: When comparing RWHP ratings assume a 20%- 25% RWHP Dyno Correction Factor Chart to accommodate for transmission and drivetrain power losses. Additional factors to consider in the calculations include inherent vehicle powertrain variabilities, ambient temperature, relative humidity, altitude of the test location, etc.
