Steeda 2018+ Q500 Enforcer SSV Mustang GT

The Steeda Q500 was designed for hardcore, power-hungry performance enthusiasts who want the most Mustang muscle for their money, period.  

It starts with the 5.0-liter aluminum 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.

Inspired by the track

Engineered for the road

Steeda Q-Series Mustangs are the most uncompromising and best performing road cars Steeda has ever produced. Homologated and registered in the UK as a STEEDA Mustang, and NOT as a Ford, these incredible cars take the Mustang to a whole new level in Europe. Collectable and driveable, the Q-Series Mustangs are the perfect choice for the driving enthusiast.

Strategically engineered to meet the challenging demands of motorsports enthusiasts, every Q-Series Mustang is optimized for maximum performance by pushing the limits to the extreme – both on & off the track.  

The Q-Series Mustangs offers appearance & performance that is defined by being muscular, powerful and athletic making a clear statement of unrivalled performance at every twist and turn in the road ahead.

Pumped-up Mustangs not doing it for you? Then Steeda’s more subtle changes could be the answer

A modified Mustang that's made better without monster power. No, really...

It feels tight and together on the road. Genuinely. It goes down a B-road with way more control and precision than the standard car.


Realizing that power means nothing without stability and control, the Steeda G-Trac Suspension and chassis modifications have been strategically engineered to break the performance boundaries of the S550 Mustang.   The result is a level of performance that makes for an unbeatable combination on the street, racetrack or dragstrip – all without sacrifice.

For our Steeda Q-Series Mustang, we have undertaken unprecedented measures focusing on dramatically enhancing the driving dynamics of the  S550 Mustang.  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 Q-Series Mustang 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.

The fitment of lightweight staggered 20” wheels and Michelin High Performance tyres round out the package and not only adds an aggressive look, but they also reduces un-sprung weight, further enhancing the performance and providing a far superior level of car-to-road adhesion.


The Steeda Special Operations Team developed a proprietary Cold Air Intake system that incorporates an industry exclusive integrated billet aluminum velocity stack.  This feature dramatically increases and stabilizes the flow of cool incoming air to the engine and when combined with our performance engine calibrations, the results are nothing short of spectacular. 

Properly calibrating a modern Mustang is exceptionally difficult because of the increased complexity built into the vehicles electronics and the interconnected 22 different computer modules. We have successfully calibrated the new advanced Ford system and have developed and refined hardware and calibrations for both naturally aspirated and supercharged applications that provide a level of performance that is unrivaled in the industry today - all without compromising drivability or durability.  

We are the only aftermarket manufacture today that offers these increased levels of power with the delicate refinement needed for everyday driving.   From mild to wild, from street to track, our performance tuning provides sharper throttle response, intense power, and unprecedented performance – all delivering on the Steeda motto that says “Speed Matters®”
