Porsche  ended production for the 997 Turbo Cabriolet  back in 2012, having replaced it with the current generation 991. But, even if it has been close to four years since we last saw the 997 Turbo Cabriolet, German tuner Wimmer RS still took time to build an impressive kit for the previous-generation 911. If you think about it, any kit that promises up to 840 horsepower of performance is incredible, even if the model has been gone for a long time.

That’s what we have here with this kit from Wimmer. It’s not one of those overblown kits that come with a grocery list of aerodynamic components and interior upgrades. In fact, it has neither of those things. But, anybody who does avail of this program will have no trouble accepting the absence of these items because the engine upgrade that it does have has the capacity to bring the car’s performance capability to a whole new stratosphere.

Think this Wimmer kit is dated? Let me be the first to tell you that you’re not going to feel that way once you step inside a 977 Turbo Cabriolet with this program firmly entrenched in it. On the aesthetic side, it even has a unique body wrap that’ll ensure that all eyes will be glued to this 977 Turbo Cabriolet when it’s on the road.

There are a lot of things to like about this program for the 997 Turbo Cabriolet by Wimmer RS. I’m sure those who end up getting it will have no problems agreeing with that sentiment.

The exterior modifications on the Porsche 997 Turbo Cabriolet are limited to just a gold body wrap that gives the sports car a nice shine and a new set of wheels. The car looks especially glamorous at night, especially when the lights bounce off the body wrap, creating this shimmering look that really brings out the aesthetic appeal of the sports car.

As for those wheels, Wimmer R.S chose a set of 19-inch O.Z.-Ultraleggera rims shod in Micheline tires measuring 235/35-19 in the front and 305/30-19 at the back. Wheel spacers measuring 0.98 inches on the rear axle round out the wheel-and-tire modifications on the car. Other than these two additions, the exterior of the 997 Turbo Cabriolet remains in stock configuration. No changes were made to the interior of the 997 Turbo Cabriolet so don’t expect anything out of the ordinary when you step inside the cabin. Fortunately, Porsche already put in the work to make the interior as classy and as luxurious as it can possibly be.

OK, so the rather muted upgrades on the exterior and interior aren’t worth bragging about. That’s ok because whatever it lacked on those two fronts, Wimmer RS more than made up for in the engine and performance department. That’s right. This program for the 997 Turbo Cabriolet is all about adding more muscle to the car’s 3.6-liter, flat-six engine. On this end, the German tuner added a pair of turbochargers and worked on optimizing the electronic makeup of the flat-six mill.

Other updates like the new spark plugs, reinforced pressure tubes, and a more powerful fuel pump all contribute in improving the sports car’s output from the standard 480 horsepower and 457 pound-feet of torque numbers all the way up to an incredible 840 ponies and 642 pound-feet of torque. Simmer also added a stainless steel racing sports exhaust system with electronic valve command and sports catalysts to help accommodate the increased power coming out of the flat-six engine.

No performance numbers were announced, but considering the massive horsepower improvement of the car, this 997 Turbo Cabriolet could sprint from 0 to 60 mph in under three seconds to go with a top speed that could reach in excess of 210 mph. Those numbers aren’t official by any means, but one can only imagine that this 997 Turbo Cabriolet is capable of unspeakable fury on the road with that much power under its hood. To accommodate the power gains of the Porsche, Wimmer RS also added a few suspension improvements, including the KW variant 3 coilovers.

With the amount of power Wimmer RS was able to get out of the 997 Turbo Cabriolet, it’s safe to say that availing this package comes at a steep price. Well, that’s exactly the case, because the German tuner is charging €39,000 for just the technical optimization program. That’s about $42,400 based on current exchange rates. Oh, but that’s all. You know the upgrades on the chassis and suspension, as well as the new wheel and tire offerings? Those are going to cost an extra €7,500 ($8,150), bringing the total cost for the entire program at €47,150, or around $51,271.
