Employing championship racing experience and rigorous engineering, research, and development methodologies, Steeda has earned its place as a top-tier Mustang tuner. But the 2010 Steeda Q550 "Streetfighter" Mustang might just be the best all-around Mustang ever built. --TMSBrad


The Los Angeles Auto Show was the forum for the world debut of an all-new ultimate street performance vehicle: The 2010 Steeda Q550 Streetfighter Edition. Destined to reign supreme in the Pony Wars – this high performance muscle machine is part of our continuous evolution of Steeda Autosports building the best performing Mustangs available anywhere. Conceived as the ideal Mustang that can be comfortably driven daily, it has all the necessary equipment to be a weekend warrior on the racetrack/drag-strip without worry.

Equipped with the most extensive amount of standard suspension upgrades we have ever included on one of our production vehicles - including our Watt’s Link Suspension system - this performance Mustang can easily pull 1.2gs, and with it’s broad range of brutal power it has on demand, it can rip off 0-60 times that are less than 4 seconds with quarter mile times comfortably in the 11 second range. There is simply no other serialized Mustang available today that offers the performance, styling, and performance attitude that this Mustang has.

"The Steeda Q550 Streetfighter achieves its massive power output from the Ford Racing/Whipple Supercharger assembly. We selected the Ford Racing/Whipple supercharger application because it provides its power reliably over a broad rpm range on 93 octane fuel and is fully 50 state emission legal”, commented Dario Orlando, President of Steeda Autosports. "Delivering smooth power throughout the power curve is what this power package provides and it is a perfect power source for the Steeda Q550 Streetfighter Edition. When mated with our unique performance pulley system and our other engine performance enhancements, this package really delivers the mail!

Jamie Allison, Ford Racing Performance Group Manager adds: “Dario Orlando and the entire team at Steeda Autosports have been a longtime and valued partner of Ford Racing and have many aftermarket offerings to choose from. We are excited and proud that they chose the FR 550HP supercharger to power their new Q550 Streetfighter Edition”.


In addition to the supercharger assembly, the Q550’s powertrain also is equipped with:

• Steeda custom engine calibration
• Steeda 11-13 psi belt drive kit
• Steeda Tri-Ax® Shifter
• Speed of Sound A-Pillar gauge cluster with Aeroforce gauges

Engine power is just part of the success story about the Q550 Streetfighter. While the exterior shares the same aerodynamic body modifications of the Q350 with the unique Steeda front fascia with openings for front brake duct cooling, the facia also incorporates unique vented openings for additional cooling. Additional exterior enhancements include:

• Steeda rear spoiler tuned for maximum down force with the least amount of aerodynamic drag
• Steeda rear facia that exhausts air from under the vehicle with extreme aero efficiency and minimal aerodynamic drag
• Unique Steeda vented hood that exhausts the hot power robbing engine heat out and over the hood into the vehicle’s slipstream with amazing efficiency.

“The real beauty of this performance monster lies underneath the vehicle. That is where we deployed every performance handling trick we have in our arsenal” commented Steve Chichisola, Master Mechanic/Technician at Steeda Autosports. “We have integrated the knowledgebase we acquired over the last 21 continuous years of building high performance Mustangs – more than any other Mustang aftermarket modifier - all into one fully cohesive package where ALL the parts are perfectly tuned to work in harmony towards delivering maximum suspension performance.” The suspension modifications include:

• Steeda/Tokico D-Spec shocks and struts
• Steeda Upper Strut Mount Kit
• Steeda Adjustable 3rd-Link Trailing Arm Kit
• Steeda Lower Trailing Arm relocation brackets
• Steeda Billet Lower Trailing Arms
• Steeda X5 Ball Joint Kit
• Steeda Bumpsteer Kit
• Steeda Rear Swaybar
• Steeda Rear Swaybar billet endlinks
• Steeda Adjustable Front Swaybar
• Steeda Watts Linkage kit
• Steeda 3-point Frame Rail & Torque Box Brace Kit

The interior is yet another area where this vehicle speaks performance. Inside you will find it’s interior very sleek, athletic, and totally ready for aggressive driving. From the illuminated Steeda doors sills that greet you when you open the door, the interior includes the following performance related amenities:

• A thick, Alcantara leather wrapped steering wheel assures a firm and secure grip during performance maneuvers
• Body hugging, adjustable, leather covered, carbon fiber backed Steeda Sport Seats
• Safecraft Safety Equipment 6-Point Safety Harness
• Safecraft fire extinguisher system
• Four-point, leather wrapped DOM steel roll bar with cross bracing
• Steeda floor mats

To plant the power to the pavement and also to ensure secure stopping power during the most aggressive conditions, the Q550 Streetfighter includes:

• HRE Monoblock P40 wheels (20” x 9.5” front, 20” x 11” rear) with a brushed finish
• Nitto NT05 High Performance tires (275/35 front, 315/35 rear)
• Steeda/Baer 6-Piston High Performance Brake Package (six piston front –and- six piston rear brakes) with 15” crossed drilled and slotted rotors

The Steeda Q550 Streetfighter Edition will be available in the 1st quarter of 2010 from select Steeda Autosports authorized dealers. Look for additional updates in the near future regarding pricing and availability of this limited edition performance vehicle.

 

Those HRE Monoblock wheels are sick and compliment the new 2010 body style so well. There are afew tuner stangs using those wheels now. They may be end up being the aftermarket equivalents to the CCW deep dish wheels on the 03 04 cobras.

Too bad they are deathly expensive.

 

Can it really rip off sub 4 second 0-60 and 11 second range 1/4 mile times with the stock wheels and tires? My GT500 has problems hooking up on the 19's and with these 20's I would imagine it's worse. Looks like a real nice aftermarket GT though!

 

That's the best looking 2010 I've seen yet. GORGEOUS! 1.2G's? 0-60 < 4?

I'm off to rob a bank...

 

Very nice.
Not sure what "Alcantara Leather" on the steering wheel is though -- doesn't it have to be one or the other?

 

Probably uses the GT500 Steering wheel

 

Is this thing at the LA auto show? I'm going tommorrow.

Dave

 

Yup, I can't wait to see it either

Need a getaway driver? I need just enough to buy one of these... and maybe a new Saleen...

 

Love that front bumper and wheels! I would love to get that when I finally get mine!

Props to Steeda, those numbers are impressive. I could only imagine how much more potent that would be with the 5.0 in it and some work done....

 

HRE P40s are huge in the Porsche community. Love them...I wouldn't do 20's I'd stick with 19's. A 355/35/20 is 28.6" tall..why would they use that size? A 325/35/19 would be just under 27" (OEM) at 26.77" along with the 285/35/19's at 26.73". Granted these sizes aren't available with the NT05's but they are available with the Invo's.

Can I get in on this? Somebody has to look out for cops!

And thanks for the pics TN. Best looking front valance yet

 

This. Gus, if you're reading this, when can we get the front bumper separately for those who already got a '10?

I like the wheels, but I don't want to know how much they cost.

 

They're HRE's. They're going to be expensive.

 

Delete the side stripes and the Q550 in nothing less than impressive. The only questionable item is there is no mention of upgraded internals to sustain such level of performance not to mention the justification for its likely price tag.

 

I want those seats. Time to go look at the Steeda site!

 

In that size $5K for just the wheels....

Dave

 

Well, those aren't in the catalog just yet I suppose.

 

Any estimate on price yet?
