We don't really need to justify the attraction of the 991 GT3; you've been reading about its near-perfect balance of handling, braking, and driver involvement since it launched in 2015. This is, without question, one of the racetrack and canyon carving all-stars of the current millennium. The owner of the car you see here, Chris Jurilla, a mortgage specialist from Yorba Linda, California, noted its naturally aspirated power delivery and 9,000-rpm redline as two of his favorite features. He also pointed out that its color, Paint to Sample Mode Grau (Fashion Grey), was another driving force in his decision to purchase the car.

The 991 GT3 is one of 30 cars available in 2015 with the choice of three PTS colors, so that makes this one very rare—reportedly one of only 10 such cars of this color in the U.S. The paint is based on, but not identical, to an original 356 color. It's been revived a few times since its inception and given a modern interpretation, but you can't deny its timeless beauty, especially on a car as potent as the GT3.

So what led him to modify this future collectible? "I know the purist will think its heresy, but I wanted to give the car a motorsport-inspired theme," Chris explained. "Most people slap on fender flares and a big wing and call it done. I didn't want the big wing but wanted to go the extra mile, so I worked with Eric Nareshni at Supreme Power Parts in Placentia, California, to find genuine Porsche Motorsport parts.

"Eric had previously built a 991 Carrera S, which was featured in european car magazine; I really liked it. He'd also worked on my BMWs, so I knew his work."

Mr. Nareshni is a man with long fingers. In this instance, they reached out to a contact in Porsche Motorsport who was able to source the genuine Cup front end. When you question Eric about the origin of the unicorn poop, he shifts around and won't look you in the eye. It's a question best not pursued. Let's just say he has developed many fruitful relationships over the years.

The unobtainium Cup conversion was then fitted by Strasse Sport in Irwindale, California. Ivan Madrigal was charged with installing the Cup front bumper, hood, fenders, fenders flares, and lip spoiler. Those ducts on the hood are intended to direct air to cool the driver, although they don't serve that function here. The car does get the Cup reinforcement bar and tow hook; a man in Stuttgart is owed several thousand dollars and a case of beer for his efforts.

Naturally, everything was expertly painted Modegrau to give it a clean, OEM+ appearance that has the non-cognoscenti scratching their heads to discover why it looks so good.

Part of the car's appeal is undoubtedly its stance. That comes courtesy of Eric, who specializes in low and wide. In keeping with the race theme, a set of BBS Motorsport E07 wheels were ordered. Eric then swapped the front barrels for wider pieces to give the car a wider track and to better fill the extended fenders.

The final element was the suspension, which was fettled by Joey Seely at E-Motion Engineering in Newport Beach, California. He adjusted the ride height, fitted Tarrett Engineering sway bar endlinks, and corner balanced the car. "He's a magician!" Chris exclaimed. "He dialed in the car perfectly. It drives so well."

Handling was further enhanced with the inclusion of a BBI Autosport Street Cup rollbar, which was custom painted Fashion Grey. By stiffening the chassis, it makes steering inputs and suspension responses more precise. It also further reinforces Jurilla's motorsport theme for the car.

As if further embellishment were needed, the interior also received a pair of Recaro Pole Position seats for reasons of both form and function. These are among the very best seats available on the aftermarket and none of us need an explanation as to why he would want them.

Finally, Chris felt the car could use a little more straight-line performance to back up its looks. After some experimentation with other brands, he would eventually settle on a set of Dundon Motorsports long-tube race headers. "I tried some others but Dundon's motorsport history and the amazing quality won the day. They gave me an additional 40 hp at the wheels and my setup allowed me to retain the factory valving, so the car isn't too loud, unless you really get on it," Chris emphasized.

The headers were mated to a lush Akrapovic Sports Cup line titanium exhaust, which will make most Porsche owners drool. There are also BMC air filters under the hood to ensure the best airflow possible.

"Having worked my way through a string of high-performance European cars, I can't believe how good the GT3 is," Chris exclaimed. "It's great for the track and canyons, but it's still capable in traffic and looks good when you valet at a restaurant."

Despite his obvious enthusiasm for the GT3, it was actually returned to stock and prepared for sale while we were writing this. The reason? A brand-new GT3 RS was too much of a temptation. "It's one of the first in the country and I'm so excited to get my hands on it," he confessed.

We can report that the RS is at Supreme Power Parts for a major overhaul, and the initial glimpses look very promising. Chris also has his eye on the next shipment of GT3s that is rumored to be arriving with a manual transmission. "I wanted to sell the current GT3 to make way for the RS and give me an option on the manual transmission cars if they do arrive," he told us. No doubt he's already scheming how to personalize that car in his distinctive but stylized way. Porsche purists might want to turn the page and try to forget they ever saw this, but the rest of us need only wait to see what he has in store.
