For those who are paying close attention to the aftermarket industry, this years SEMA Show might always be remembered as the year RAUH-Welt became a household name. Well, maybe just among car nuts.

RAUH-Welt Begriff or RWB for short, is a small Japanese tuner known for its wildly customized air cooled Porsches, with big fender flares and even bigger spoilers. To the best of our knowledge, no RWB has ever been on display at SEMA, and to make these cars even more special, they are the first to be built in America.

The light green car (above) sits as the main attraction at the Falken tires booth, while the white car (below) belongs to former 0-60 Magazine editor-in-chief Brian Scotto. Scotto now works for Ken Block, managing his new Hoonigan brand and so we’re certain the car has plans beyond just the SEMA Show.

We expect to see numerous other RWB Porsches at SEMA next year and there’s already evidence the trend is catching on. We spotted a few similarly-styled German sports cars and have included them below. Enjoy responsibly.

If you’re familiar with German Porsche-tuner Gemballa’s modified Carrera GT, the Mirage GT, stop reading.

No really; just shuffle through the gallery of photos below and be done with it. We’re the first to admit that there isn’t much new with Gemballa’s Gold Edition of the car, but it sure is worth a look.

In standard trim the Mirage GT gets plenty of carbon fiber bodywork and a slight power boost, bringing the 5.7-liter V10 engine to 670hp. This is good for an improved 0-60 mph time of 3.7 seconds, versus a 3.9 for the stock car. The top speed also gets a bump from 205 to 208 mph.

What makes this particular model the Gold Edition is, well, all the gold. The Mirage GT sports gold center-locking wheels, gold painted side skirts, a gold air intake, gold trunk lid, gold brak ecalipers, gold brake vents and gold mirrors. Even the engine bay gets the gold treatment. And don’t forget the interior. There you’ll find gold painted air vents adn even the HVAC and shifter surround.

Not being overly stuck on tradition, Gemballa also tossed the birch/ash shift knob (used on the Carrera GT in homage to the Porsche 917) in favor of a carbon fiber unit.

Gemballa says it will build just five of these Gold Edition model to retain their exclusivity, but we bet they only build one. Still, we have to hand it to Gemballa for pumping out this many versions of the Mirage GT, especially considering Porsche only ever built 1,270 Carrera GTs.

No pricing has been released but knowing Gemballa we’re sure this special edition Mirage GT costs about the same as its weight in gold.
