Lose Your Innocence in 3.1 Seconds

The guiding Steeda principal is simple - Speed Matters®. Maximum Performance is achieved by a unique blend of More Power, More Traction, and More Refinement. For the Q850 StreetFighter™ Edition we’ve given it everything it needs – not just to survive on the street & racetrack – but to blow others away. From idle to redline, our special engine calibration starts where others left off – delivering a confident power that is rapid, responsive, and optimised for maximum performance. Throttle response is immediate and predictable and when coupled with our exclusive suspension and chassis modifications, you have the perfect combination of unrivalled performance for every twist and turn in the road ahead.

Argument Against Status Quo

Realising 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 platform. The result is a level of performance that makes for an unbeatable combination on the street, racetrack or drag strip – all without sacrifice or compromise.

A Sum Far Greater Than The Parts

We have undertaken unprecedented measures focusing on dramatically enhancing 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. The Steeda Q850 StreetFighter™ Edition a level of excitement and driving that delivers practically zero pitch and roll and a level of suspension refinement/performance that has never been experienced in a production Mustang before.

The fitment of lightweight staggered 20” wheels and Nitto NT555 G2 Ultra High Performance tyres round out the package and not only adds an aggressive look, but they also reduces un-sprung weight, further enhancing performance and providing a far superior level of car-to-road adhesion.

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 to function at speed. From the Steeda lowering springs that provide the optimum height for aerodynamic and suspension performance, the front fascia that provides minimum drag and the appropriate level of downforce (aiding the front tyres to get more grip and providing reduce understeer tendencies), to the rear spoiler that achieves the proper balance of downforce and drag. All of our aerodynamic enhancements not only improves the overall appearance of the car, but also it’s traction, grip, and lateral dynamics, which together hint at the car’s hunger for optimum performance.
