Porsche`s 911 GT2 provides one of the most
Porsche’s 911 GT2 provides one of the most addictive, accelerative and awe inspiring experiences you can have behind the wheel of a 911, but Oakley Design has moved the game on with its new range of tuning products for the scariest 911. Story: Stuart Gallagher Photography: Andy Morgan (action) and John Colley (studio) he moment the first non-Porsche employee extricated themselves from the carbon fibre framed Recaro bucket seat of a 997 GT2 I doubt he suggested that, with 530hp and 507lb ft of VTG produced grunt, it needed some extra shove. For not only is the current GT2 (which is sold out in the UK, incidentally) the most powerful 911 the company has ever produced, it as also one of the most gut-wrenchingly exciting, scary T 46 WWW.GTPURELYPORSCHE.COM and ferocious cars it has built, too. But like the first water-cooled GT2, the 2001 996 variant, the current GT2 is neither an easy beast to tame, nor one that you can instantly get on with and feel relaxed enough to get all 530 Stuttgart ponies out of the toy box to play with all at once. Unless, of course, you can trace your bloodline directly to anyone with the surname Rohrl. First name Walter. Areas that required concentration beyond your regular defacto 911 driving settings include stability under high speed, three figure braking, and trying to get the thing to turn-in when the entry speed is a good 20mph higher than the motorway speed limit and the corner has a tighter apex and exit than its more open entry point suggested. Call on the standard PCCB ceramiccomposite stoppers when the top of fourth gear has just been well and truly stretched and the degree to which the front end dives into the asphalt can unsettle the rear as the weight lifts off the rear axle. If it’s even slightly damp the previously sticky Michelin Pilot Sport Cups begin to fight for purchase, too. Ironically, when it comes to high speed corners you’ll be craving some of that front end weight transfer as it takes a couple of bites to get the front end hooked up with the line you’d like. Basically, there is a hint of old school 911 about how this thoroughly modern 21st Century 911 behaves in some very specific circumstances. And this is what the new boys of Porsche tuning, Oakley Design, has set out to address. We first came across Oakley Design when it presented us with its 997 GT3 back in issue 77, and its latest GT2 demonstrator features a near identical makeover. Carbon fibre splitters and aerodynamic aides designed in the MIRA windtunnel replace the original factory items, but still use the original mounting and fixing points, and the carbon fibre wheels are now forged for extra strength. Behind these live eight-piston Brembo callipers with Pagid yellow pads and 400mm carbon-ceramic discs at the front, 380mm discs and six-piston callipers at the rear. Mounted to all four corners are titanium four-way adjustable spring and damper units by Intrax and there is also a carbon fibre anti-roll bar for the rear. FEBRUARY 2009 47 oakley design GT2 Silverstone isn’t far off such a vehicle’s pace. Approaching Stowe corner at the end of the Hanger Straight you start to ask if this car isn’t too quick. And this is while pounding around the home of the British Grand Prix! The thought only occurs because you’re sitting in a road car that still has a full carpet set, air conditioning and a radio and weighs 1400kg. Through Stowe it’s just mega. As the exit of the corner tightens you can still keep on the power to get the drive down to Vale and there’s no push from the front end or waggle of the tail, just an organic and mechanical movement out to the edge of the circuit. The Vale complex highlights that even the wonders of Intrax’s finest can’t dial out the GT2’s natural tendency to understeer when you’re trying to be smooth with the throttle but at the same time get through a 90-degree greasy right-hander as quickly as possible. Into and out of Abbey sees a short-shift into third to let the torque push you through the long, never-ending corner, with fourth snatched on the exit before the big braking moment into the tighter left-right before Bridge. This slower complex highlights not only how well Oakley has set this car up for the big speed corners such as Copse and Stow, but how it has retained a level of compliance and damper control for you to take a rude amount of kerb while still opening the throttle for a quick run under Bridge before diving into the entry to the Luffield complex. Into this big braking area the GT2 maintains its composure, with less dive under braking and a rear end that feels nothing but planted to the surface. Through the Luffield complex you need a sharp, direct and grippy front end to get through as quickly as possible for the fastest possible exit on to the start-finish straight, and this GT2 delivers, again. There’s no need to fight with the helm and the encouragement this gives you to get on the power early is one of the big differences between this car and a standard GT2. When the time comes to pit there’s a disappointment that we can’t have more time in the car (and not only because someone else is picking up the bill!) because, believe it or not, this 620hp 911 GT2 is the perfect place to be when you want to move your fast driving skills up to the next level. No, really. The level of composure, feedback and reassurance that this GT2 instills in you results in your confidence building and your willingness to carry more speed in, through, and out of corners. Where you expect it to bite it puts an arm over your shoulder and guides you through every step of the way. The 911 GT2 has, in the past, been the beast you step into when you feel you’ve mastered the 911, but this example from Oakley feels the perfect companion in which to learn how to drive a 911 quickly. Really, bloody quickly ● Oakley Design offers a full range of tuning products for the 911 GT2, including windtunnel honed aerodynamic kits, carbon fibre wheels, a titanium exhaust and 622hp engine conversion, Intrax adjustable suspension and Brembo developed carbon fibre brakes. The results are simply stunning and build on all the GT2’s standard ability and performance As with its GT3 upgrade package, Oakley has also made a couple of mechanical upgrades for the GT2, too. The first of which is the fitment of its six-speed sequential gearshift system. When we tried this on the GT3 we were blown away by its simple mechanical action, the everyday usability of it and greater control – and confidence – it provides when you’re on track and the last thing you want to be worrying about is swimming around in an H-pattern full of neutrals. Oakley has also played around with the GT2’s heart. The pair of VTG turbochargers have been replaced with more traditional KKK units, the exhaust system is manufactured from titanium, the turbocharger’s headers from stainless steel and there is a factory boost pipe kit, performance air filter and a new map for the ECU. The result? 620hp produced at 6065rpm and 593lb ft of torque developed at 4805rpm (the standard GT2 develops 530hp at 6500rpm and 501lb ft of torque between 2200-4500rpm). Silverstone’s Grand Prix circuit is the venue for our test as we gatecrash one of Gold Track’s last track days of the year, and while it’s November the temperature is mild (in the early 48 WWW.GTPURELYPORSCHE.COM teens) and the early morning dampness around the circuit has all but evaporated. Everything feels immediately familiar in the GT2’s cockpit, except, of course, the beautifully crafted aluminium gearshift that looks strangely like a radio mast as it towers above the radio controls. Engage the clutch, pull the lever back for first and, aside from the heavier twin-plate clutch testing your thigh muscles, it’s business as usual. A couple of sighting laps stoke the memory banks as to how natural the sequential shift is to operate, with it dropping easily back for every upshift, but requiring a firmer, more dedicated push through the neutral gate when dropping down through the ratios. These early laps are also useful to get to know the colossal power unit sitting beyond the rear axle line. Drive in the engine’s mid-range and you ride a crest of torque that will still deliver you to highly illegal speeds with next to no effort, but after a couple of laps it feels only right to ask Oakley’s GT2 to do its best. Third, fourth and fifth gear demolish the start-finish straight and a firm shove of the middle pedal and a single push on the gearlever delivers you into Copse’s apex not only at a pace that would have your buttocks clamping the seat’s fire retardant material in the standard car, but with a front end that sticks to your chosen line like no other GT2 we’ve tried. The Pirelli P Zero Corsa rubber Oakley prefers, over Michelin’s more track-orientated Cup tyre, develops an immense level of grip, with the outside front feeling like it would need a small nuclear explosion to dislodge it. The power can be unleashed the moment the apex has been met and as the lock winds off you can climb into the power band and explode along the small straight up to the Beckets/Maggots series of corners. Again it’s the grip that overwhelms as you scythe through this left-right-left-right sequence, and on the second and third circuits the confidence is there to carry such speed through this complex that it is slightly bewildering if you’ve only ever driven here before in a road car. A GT2 is far from a lithe, slick shod, motorbikeengined track car with a number plate stuck to its Le Mans-style bodywork, but the pace achievable by the Oakley GT2 around FEBRUARY 2009 49
