Ford tuner Steeda has released its take on the S650 Mustang, called the Q850 StreetFighter. According to Steeda it’s “the most advanced performance Mustang” it’s ever released, thanks to 37 years of tuning pony cars. It’s also designed for road or track use. That’s some big talk.
A respected automotive brand is bringing manual transmissions back.
Of course, Steeda backs that up with some big improvements to the S650 Mustang GT. It starts with a Whipple supercharger bolted onto the Coyote V8, pushing peak output to 810-horsepower and 640 lb.-ft. of torque. That’s enough to get the pony really galloping.
But as they say, a lot of power is useless if you can’t control it. For that, Steeda developed a completely new G-Trac Fully Adjustable Suspension/Chassis Package. The company claims that adding just that to a stock Mustang shaves 7 seconds off the lap time at Sebring. Nice.
Included in the package are coilovers up front, shocks in the rear, bump steer correction kit, billet aluminum subframe support bushing inserts, IRS subframe bracing system, adjustable sway bars with CNC billet ends, and front chassis bracing. All that is supposed to tighten up handling and increase responsiveness, helping the Mustang to corner much better.
Plus, there’s a Stage II G-Trac Fully Adjustable Suspension/Chassis Package for customers looking to really get serious about handling.
Another offering for the Q850 StreetFighter is a carbon fiber package. Parts included are the race wing, lip spoiler, mirror caps, vents, and door sills. We’re unsure how much curb weight that sheds, but the parts look cool.
Customers can also get an upgraded brake system, four-point roll cage with rear seat delete, six-point safety harness, a leather and carbon fiber steering wheel, and a race-inspired leather upholstery package.
Buyers can also add bespoke upgrades to their Mustang, for a price.
Steeda says it used both Sebring International Raceway and the Nurburgring Nordschleife in the testing of the Q850 StreetFighter. That’s impressive and quite the testament to the company’s development process.
