We are less in love with the droopy “Dali clocks” automated rear wing of the Porsche GT2 than we are with the gorgeous spectacle put on by the wing of the GT3. So TechArt and the client are to be applauded for thinking likewise and fitting this custom 55-inch carbon-fiber, hollow master of rear downforce. The unit is adjustable in height over a 1.6-inch range and it was set at a default mid-point for our test day. Again, the sucked-to-the-pavement feeling at speed is not to be believed. Oh, for a suitable track to really explore the late braking and stability to the hilt. Throughout it all, the mechanical limited-slip differential works full-time and we don’t necessarily need a track day to feel that.
The brakes remain Porsche’s lauded PCCB set (15-inch front, 13.8-inch rear rotors) that supply more than enough stopping power, complementing the smooth operation of the 3,185-pound hound (that’s full curb weight). And with the two TechArt heavily modified variable turbine geometry turbochargers with augmented turbo body and turbine sides for 26.1 psi maximum boost pressure, the 27 percent greater torque pounding the pavement needs these stoppers like never before. With so much judicious pedal hammering going on, we grew to appreciate all of the study Porsche testers put in to establishing just the right pedal feel under the most stressful of situations. At the same time, heel-and-toeing is easy to do and is crucial to the overall raison d’être of the car anyway.
Despite the greater flow through the stainless steel exhaust manifolds and pipe system running out the back, the famed 3.6-liter flat six still sounds like the world’s most insanely powerful Shop-Vac. We want so badly for more rumble and roar, or at least a more meaty sound, to leap forth from our Porsches, but all we ever get is a raspy forced-air hurricane. With the Sport button lit, the sound inside the car gets correct and deep, but outside little changes. Oh well, at least the sucker doth haul ass in the end, handles like there’s Velcro at each corner and sets quite the tone both outside and in. We could see acceleration arriving at sub-3.0 seconds, but the manual shifter and rear traction would probably relegate it to around 3.1 seconds in reality. Top speed on the Nürburgring Nordschleife’s Döttinger Höhe final, long straight reaches an unofficial 217 mph.
TechArt knows Porsche like no one else and it was they who originated all those years ago the Porsche catalog of Tequipment enhancements. But their interior work takes just as much center stage as does their powertrain and chassis tuning. There is a tendency these days to err on the Alcantara overkill side and, as our hosts reminded us, “The customer is king in the end.” Look at the quilted roof and even the quilted inner side of the front hood. All done gorgeously, but… c’mon. The entire interior is redone by TechArt in house in Leonberg and we could happily snooze away an afternoon in the one-piece carbon-fiber sport seats. Instrument dials are TechArt specific, as is the outer portion of the steering wheel, the re-covered gearshift and handbrake, plus, of course, all the “GTStreet RS” placards and embroidery. Don’t ask us what the customer’s “Ting & Tiger – One of One” is getting at. To each his own.
Back outdoors, the hood is in carbon fiber and works with the front fascia to guide air more efficiently for a coefficient of drag just a bit better than the standard 0.34 Cd, despite the added downforce both front and rear. The front fenders are also in carbon fiber, while the engine cover is in fiberglass. Besides the exclusivity and lightness factors, the processes to forming these panels these days in these materials is advantageous for achieving exactly the desired characteristics. To help with driveway inclines et al., the front Vario suspension fitted by TechArt to their specification has hydraulic lifters that bring that chin spoiler up about 2.5 additional inches.
This customer car was not allowed on to public roads for obvious reasons, but the artificially liberating airfield just allowed us to play to the extreme, and we appreciated the wild opportunity. The entire package is insane and a Porsche of this caliber set loose can be frightening as that front end lightens up, as it will so frequently do. But then it forces one to be the very best driver possible, drawing on every single track day instruction session and all the weekend race experience just to keep things cool under heat. As a swan song to the 997 generation of cars, TechArt has formulated a right and proper send-off. For those in the dough.
Just please try to avoid the super-saturated overuse of certain colors when you order yours.
