When you’re talking about a European-based tuner that has proven its worth building programs for American muscle cars, the first name that comes to mind is Geiger Cars. There are others, though, that are also worth mentioning, one of which is Schropp Tuning. Also located in Germany, Schropp is still trying to make a name for itself in this segment, and so far it’s done a good job at thanks to programs like the SF600R kit for the all-American Ford Mustang.

The program is actually based on the Mustang GT and questionable appearances aside, the SF600R program is actually very promising from a performance point of view. There are two different engine upgrade programs in total, one of which brings the muscle car’s output up to over 800 horsepower. With that kind of power under its hood, a Schropp-tuned Mustang can do serious damage on a race track. Fortunately, the tuner also complemented the engine kit with other mechanical upgrades, most notably the suspension and brakes. There’s a rather interesting wrap and a number of aerodynamic kits to help round out the menu of offerings that are included in the SF600R program. It’s certainly not the best tuning kit we’ve seen on a Mustang, but for a tuner that isn’t as known in the aftermarket circles as some of its contemporaries, Schropp Tuning’s SF600R kit is a good way for the company to get some attention.

Continue after the jump to read more about the Ford Mustang SF600R by Schropp Tuning.

Exterior

If you’re expecting a full-blown aerodynamic body kit here, then you’re going to be disappointed. but if you’re looking for a muscle car that’s dripping in a fancy wrap with some aero bits here and there, then you’re going to like what Schropp Tuning has to offer. For starters, that heavy, camouflage-looking, neon green wrap comes courtesy of WRAPworks, a company that specializes in creating attention-grabbing wraps. It certainly lived up to its reputation because that wrap is such an attention trap that all other exterior upgrades become harder to notice. Those who look closer will notice that the Mustang GT also gets a spate of aerodynamic components, including a carbon fiber front splitter in the front, an open front grille, and a large FM-05-R rear wing at the back.

Plenty of other options to choose from

Depending on your perspective, these upgrades can be described in a number of different ways. In some ways, it’s a lot like what London-based dealership Sutton Bespoke did when it took a stab at creating an aftermarket program for the Mustang. That kit didn’t come with an ostentatious wrap like the one WRAPworks prepared for the Mustang, but it did get significant modifications of its own. The most prominent of these mods is the aero body kit, which consists of a carbon fiber front splitter, side skirts, and even more carbon fiber pieces on the custom rear valence and trunk lid. In addition, Sutton Bespoke also got rid of the ’Stang’s traditional hood, replacing it instead with a version that features a massive hood scoop in the vein of what we normally see on the Shelby Super Snake.

In the vein of the front grille-less blueprint comes this kit from the aforementioned Geiger Cars. Unveiled in April 2016, Geiger Cars’ program for the Mustang comes with its own version of a carbon fiber-clad aero kit. Among the notable pieces include a front splitter, side skirts, a trunk-mounted rear spoiler, and a rear diffuser. It also doesn’t have Ford’s traditional grille for the muscle car and in its place is a pair of carbon fiber flat pillars.

Interior

There doesn’t appear to be any significant changes to the interior of the Ford Mustang GT in this case. There is a photo of the cabin that focuses on the car’s steering wheel. A closer look reveals that the steering has been dressed in Alcantara. There’s also a red strip at the 12 o’clock position and red stitching to boot. Other than that, don’t expect anything out of the ordinary as far as what Schropp did to the interior of the car. The same kind of expectations should be observed when it comes to other programs for the Mustang. Neither Geiger Cars nor Roush Performance developed any sort of modifications to this section of the muscle car, leaving it completely in standard guise.

One of the few exceptions though is Sutton Bespoke, which has an interior upgrade program consisting of a bespoke carbon fiber dashboard, custom Recaro sports seats, and a short-throw shifter that’s far more of a mechanical upgrade than a cosmetic one. That said, the dealership does offer what it calls the “Sutton Bespoke treatment” that uses premium materials like Alcantara, Napa and English hides, wood veneers, and piano black lacquer, among other things.

If customers intend to dress up their Mustangs past the point of its traditional look, the best way to go about it is to go to Ford directly. The automaker has a good number of add-ons, accessories, and packages that are ready to be installed on the Mustang’s interior, provided that the owner agrees to pay their cost. A good example of these packages is the California Special, which comes with Ebony leather, Miko suede seat inserts with red contrast stitching, and bespoke aluminum, among other goodies.

Drivetrain

Often times, a tuner really proves its worth in this section. The traditional formula goes, “the bigger the power gains, the better it looks to clients.” On that note, Schropp Tuning made a good account of itself with its engine upgrade program for the Ford Mustang GT. The kit itself is broken down into two separate stages. The first of these two stages is the SF600 and its primary selling point is the addition of a supercharger to the Mustang’s renowned 5.0-liter V-8 engine and an ECU remap thrown in for good measure. The end result is an output of 600 horsepower, which represents an increase of around 150 ponies to the car’s standard output of 455 ponies.

The increased output is impressive, but if customers are looking for something a little more on the “extra” side, they can avail of the SF600R conversion that puts in enough power to “guarantee major league supercar performance.” Those are lofty promises, but to its credit, Schropp did put in the work to ensure those kinds of gains. For one, there’s a new Coyote engine block with updated cylinder liners, race-grade low compression pistons that are connected to a steel billet crankshaft, a high-flow oil pump, a custom exhaust system with four branch manifolds, HJS 200-cell free flow sport catalytic converters, and three-inch diameter pipes. In full bloom and running on the right kind of fuel, Schropp Tuning’s SF600R program for the Ford Mustang GT gives the pony car an output of 807 horsepower and 700 pound-feet of torque. The tuner didn’t say how this increase in power translates to improved performance, but if you base it on other programs that offer similar power gains, a sprint to 60 mph could be accomplished in about 2.7 seconds before zooming to a top speed of over 200 mph.

It goes without saying that Schropp Tuning has an impressive tuning kit on its hands. The bad news is that it’s a program for a car that has no shortage of them. It’s not just Sutton Bespoke, Geiger Cars, and Roush Performance either. Other tuners like Hennessey have their own kits available for the Mustang, and the best part about these kits is that all of them pack power increases in the vicinity of 800 ponies.

Sutton Bespoke, for example, has an engine upgrade program that nets 800 horsepower. It accomplished that by dropping a Stage 2 Whipple supercharger and an upgraded intercooler into the engine while also adding new injectors and a larger throttle body. Altogether, the Mustang’s Coyote V-8 now packs 800 ponies and presumably around a conservative 600 pound-feet of torque.

Geiger Cars isn’t any different either in terms of its total power gains, even if it took a different route of installing a 2.9-liter supercharger to go along with a handful of new parts, including a new crankshaft, forged pistons, steel connecting rods, a cold air intake system, and a stainless steel sports exhaust system. With all these upgrades in place, Geiger manages to squeeze out 820 horsepower and 560 pound-feet of twist for the Mustang GT.

Then there’s Roush Performance, considered by many as one of the most proficient tuners of Ford Mustangs anywhere in the business. It certainly lived up to its reputation with its Trak Pak program for the ‘Stang. The highlight of this three-stage kit is its own supercharger upgrade and a fuel pump booster kit that work together to help the V-8 mill increase its output to a stout 850 horsepower.

Suffice to say, there are plenty of options to choose from here. To make things a little clearer, check out the table below to see how each tuner stacks up against the competition.

Suspension

The massive increase in power calls for equal attention on improving the Mustang’s handling capabilities. It certainly wouldn’t be a good idea for an owner to get an engine upgrade from Schropp without getting the suspension upgrades to match the power gains. The good news is that the tuner is offering modifications on this end, namely a KW 3 coilover suspension kit and a carbon front suspension tower brace. Get these two together and you’re less likely to lose control of your Mustang when you’re trying to squeeze as much power out of it as possible.

Pricing

No pricing numbers have been released as far as Schropp Tuning’s SF600R program for the Mustang is concerned. If I were to make a guess at what the figure is, I’d say that it could reach around $40,000 by virtue of the wraps, the aero kit, the wheels, and the supercharger. Your best bet at this point though is to contact the tuner directly to get a proper price quote that’s broken down to the cost of each part of the kit.

2016 Mustang Gran Turismo Tribute

If you’re looking for something completely different out of your Ford Mustang kit, you might want to take a look at this project car developed by Zero to 60 Designs. Not only does it come with a body kit inspired by the Ford GT and power gains amounting to 800 horsepower, but it made such a noise at the 2016 SEMA Auto Show that Ford’s lawyers actually got involved in investigating the kit's overall design. Ultimately, it looked as if everything was smoothened out because the aftermarket company started offering the car at the end of 2016 for around $125,000 a unit.

Conclusion

It doesn’t have the name brand of a tuner like Geiger Cars, but Schropp Tuning is going to get in that place if it keeps building programs like the SF600R. It’s got a good balance of upgrades on all sections of the muscle car and with everything in place, it should be able to maximize all of them. The only thing I don’t like is the green cosmetic wrap from WRAPworks, but I’m not going to begrudge anyone who does avail of it. It’s an acquired taste at best, but fortunately, the rest of the program is not.
