Ford Mustang Steeda Q750 'Streetfighter' for sale
£250k a bit too much for the new GTD? Here's one with near-identical power for a whole lot less

You’ve likely seen the headline figures for the new Mustang GTD, not least because Ford’s monstrous road-going GT3 car doesn’t exactly fly under the radar. It was obviously going to be powered by the same 5.0-litre V8 found in the standard Mustang - as made clear by countless demo runs at various events over the summer - but we weren’t prepared for the sheer amount of ponies Ford had managed to coax out of the Voodoo stable. That’s 826hp, to be precise, paired up with 664lb ft of torque and a top speed of 202mph, making it the fastest thing the Blue Oval’s made since the GT.
It wasn’t that long ago that the Mustang was on the receiving end of the usual stick about muscle cars, something we wouldn’t dream of doing to the GTD. Not only because it looks as though it’d give us a black eye if we did, but also for the motorsport-grade hardware below its prickly skin. And that’s why it costs $325,000 (or £250k in our money), which is a darn sight cheaper than the old GT, but a humungous amount for a car that used to be the poster child of affordable performance. Fortunately, there’s a way to get GTD-levels of grunt for only a fraction of the price. And we mean a fraction.
What we have here, folks, is the Q750 ‘Streetfighter’ by UK Ford specialist Steeda and it’s every bit as ludicrous as its name would suggest. From the outside, it looks like any other Mustang GT, only with a slightly more aggressive splitter, a small boot spoiler and a set of 20-inch Velgen wheels hinting that all is not as it seems. Lurking up front is the same 5.0-litre V8 that appears in every other Mustang GT, except Steeda has slapped a Whipple supercharger on top of it and thrown in some racier components (Ford Racing half shaft, Ford Performance exhaust, remap and so on) for good measure. The outcome is a staggering 800hp and 660lb ft of torque, getting you oh-so-close to the specs of the GTD.


It’s not like Steeda called it quits after fiddling about with the engine, either. There are adjustable dampers and anti-roll bars, upgraded sway bars and the subframes have been given a good going over to tighten up any loose ends. Gearshifts for the six-speed manual have been shortened for a snappier throw, too, though the brakes don’t appear to have been touched, which given the near-doubling in power should be entertaining but they have been painted bright green to at least look as though they’ve been bulked up. Make of that what you will.
Now, as you may well know, tuners have been extracting gargantuan amounts of power from Mustangs ever since Carroll Shelby got his power-hungry mitts on the original back in 1965. But most of the modern offerings come with outlandish bodykits and ultra-focused interiors, none more so than the GTD. Bonkers name aside, the Q750 Streetfighter is much more restrained. There are no badges or special decals, just a set of Corbeau seats, the Alcantara-wrapped steering wheel from the GT350 and a small plaque in front of the passenger reading ‘Supercharged Coyote’. That’s it, and it’s all the better for it.
Remember how we said it was a fraction of the GTD’s price? The seller’s asking for £39,990, or less than a sixth of the cost of the similarly-powered road-going racer. And it’s rarer, too. Steeda only built two of them, presumably because that’s how many people it could find who were brave enough to take it on. Obviously, we’re not suggesting the two are directly comparable - especially as the GTD might be the coolest Mustang since, well, ever - but if an affordable, monumentally-powered Mustang is all you crave, you need look no further.



Would make a nice daily though plenty of power once on the move and probably sounds great.
You rarely get the cost of the modifications back, but with a £40k asking price they are trying to get the list price of all the modifications back by the looks of it. There will be many more whipple charges mustangs out there at much less.
Also… I suspect that 800bhp figure was arrived at by strapping one to a wheel dyno and calculating an estimate of bhp then rounding it up to the nearest hundred, whereas the gtd figure would be from a reputable engine dyno. I’ve heard of whipple coyotes quoted anywhere between 600-800. I suspect the real output would be much closer to 650-700 than 800bhp….
These sort of adverts are adding more fuel to the fire of boosting my mustang GT given they hold their money so well. Though I'd be going turbo instead of supercharger, just to be different!

A fellow mustang owner close to me has his at >860bhp and even he says it's not great getting going but once underway very little keeps up with it.

As mentioned, a Golf R will likely drop it from a standstill, but once rolling it will be nowhere near and you get to drive round in a Mustang with some V8 supercharger noise going on.
Im not quite ready for a change yet but would definitely go and have a look if I was, obviously there will be nothing even remotely similar when I am ready.

I hope modern Mustangs are better than the ones I tried in the States. Very average build quality (typical of many USA cars) and they not lookers are they?

I viewed it as paying £40k (new) on a 5.0 V8 engine with manual gearbox, the rest of the car just came with it

My mother in law has a BMW X1 and that has nicer interior materials but the turbo just shat itself along with some other bits at 47,000 and something miles, top build quality, can touch those soft touch plastics as you wait for the AA and pay over three grand to get it fixed.
For me, I have a Fiesta, the interior is perfectly functional but can tell its built to a price, but I tend to spend more time looking out of the window, its an absolute riot of a car, an Audi A4 would have a much nicer interior but wouldnt be as much fun.
So a Mustang for me would be an interior quality upgrade, and then there is 800 odd bhp to play with in this one.
You have to make compromises with cars, and it shouldnt be how it drives over the interior plastics, unless you have a budget to cover all bases, not sure what else you can get with 800 bhp for 40 grand that is as cool as that big grey lump sat brooding in the pictures....

They were relatively cheap though.

My X5 4.8iS only had a 4.8 V8 in comparison, but at least that never felt slow to me, but it was a bit worse on fuel at 12mpg in my hands though to be fair.
All this V8 chat makes me really want another V8 in my life, and I think the Mustang is certainly a prime candidate for that job.

I have a supercharged manual 2017 Mustang (725bhp on the dyno with a generation newer Whipple supercharger), and you've gotta know the weak point between the engine and the road. I have bigger wheels and grippier tyres, so my clutch went, then after getting that upgraded the half-shafts and diff are on the way out, but once fixed, the weak point should once again be the tyres. As mentioned above, you also need to get things like the stop-the-hop kit - it's made by Steeda so I'd really hope that they've fitted it to their own car. Getting wheel hop damages the weaker UK passenger side half-shaft.
For £40k though, assuming that there aren't any underlying issues, it's a bargain.
