Unmatched Power & Performance
At the heart of the Steeda Q850 StreetFighter is a Whipple supercharged 5.0L Coyote V8, delivering an earth-shaking 810 horsepower and 640 lb-ft of torque. However, raw power means nothing without a properly engineered suspension system to harness it—this is where Steeda’s expertise truly shines.
A Revolutionary Suspension & Chassis System
The Q850 StreetFighter features the all-new Steeda G-Trac Fully Adjustable Suspension/Chassis Package, a comprehensive engineering marvel designed to redefine precision handling and maximize power delivery to the pavement. During rigorous, like-for-like testing at Sebring International Raceway with naturally aspirated Mustangs, this suspension system proved to be 7 seconds per lap faster than a comparable stock Mustang.
Unlike conventional suspension upgrades, this complete performance system optimizes every aspect of chassis dynamics, ensuring superior handling, control, and driver confidence. This meticulously engineered system has been developed and track-tested for thousands of hours, resulting in a suspension package that outperforms all competitors.
