We use these Genuine Nismo mounts in all of our builds. A great replacement for the 20-30 year old original mounts in your GTR.
Nismo transmission and engine mounts are 30-40% stiffer than stock OEM mounts to provide precise shifting at high RPM from reduced transmission movement. The included Engine mounts prevent excess movement and assure all of the engine's power is transfered to your drivetrain properly. These mounts are an inexpensive upgrade with huge improvements.
