This time the customer wanted our stage 1 upgrade and also added a first gear kit and a stronger shift fork. The stage 1 kit consists of Gear Lock, Mechanical circlips 1 and 2, additional magnets for the oil tray, oil pump upgrade, better oil and a clean of the solenoid pack. This is a very good investment to make sure the circlips won´t fall off and cause damage to the box. Get in touch if you want us to upgrade the gearbox in your GT-R.
