As of yet, none of the information was confirmed by Nissan and we're not sure if the same rules would apply to USDM versions, but if true, it would only mean that every tuner shop would be hiring the best nerds out there to hack into this system. If anyone can make a fool out of Nissan by getting inside that impenetrable ECU, it would be Top Secret. After all, if they can make this GT-R so nice on the outside, they can make it equally fresh on the inside. Top Secret is known for turning supercars into very super-major rides with all the toppings, and a side order of coffee. It's really amazing, the horsepower they've managed to pull out of cars like the Toyota Supra and the early model Nissan Skylines. It's even equally amazing how sexy they make all their cars look.
The body kit used on this GT-R is made by Top Secret, featuring a carbon-fiber front lip, carbon-fiber front grille and an aero catch. These aero modifications may be trivial to any other stock car, but on a car that's already producing 525 hp at 6,500 rpm out of the box, these changes can make a huge difference at high speeds. The only engine modifications that Top Secret managed to put in their GT-R was their own Super Premium exhaust system and an HKS EVC, which surprisingly, didn't force the factory ECU into shutdown mode. They lowered the car using a combined set of Top Secret dampers and Swift springs. This system rides on top of a set of 20-inch Volk Racing GT-C wheels, wrapped in Bridgestone RE070 tires. The only upgrade inside are the Takata harnesses, which look somewhat weird resting on the factory seats. But it seems the overall interior doesn't need much modifying, unless you plan to make it a full-out race car.

It's for these reasons that we call this ride subtle. The GT-R's signature technology and overall high-performance attitude is still noticeable, and with the inclusion of some Top Secret science and style, the potential of the GT-R has never been more captivating. It'll be interesting to see what the future holds for this car, and we're sure that Nissan's restrictions are mere speed bumps on the road ahead.
