Cars equipped with the new Transmission Control Module have managed to out-accelerate the original spec GT-R
In addition to the change in output, which rises from 480 to 485hp, the significant change is the introduction of a new Transmission Control Module (TCM) program for the GT-R’s 6-speed dual-clutch transmission. The changes have been well documented and have come as a reaction to the monumental gearbox failures experienced by some customers using the launch control system on the original spec GT-R. Essentially, the changes are designed to optimize clutch engagement for improved drivability and improve vehicle acceleration with the car’s traction control system switched on.
Other changes to the car include an updated braking system with more rigid brake lines and brake calipers with both Nissan and Brembo labeling. The suspension also gets retuned with redesigned Bilstein shocks featuring a new valve body design and revised spring and damper rates.
The standard 20in forged aluminum-alloy wheels get a slightly darker finish and are shod with new Dunlop summer tires. Finally, a Pearl White paint scheme is now also available.
No details on pricing have been revealed but don’t expect much change from the $81,790 starting price of the base 2009 GT-R.
