Besides being a shorter shift between gears Like around an inch or so to neutral. So maybe 2-3" between 1-2, 2-3, 3-4 etc..
It is firmer than the OEM (ie. not as loose feeling)
In a nutshell it is more direct feeling.
You don't miss gears and it stays in gears. It's not hard in to or out of gear but firmer and shorter.
Good for spirited drivers, driving enthusiasts and your race car driver. (I am getting lazy)
You don't throw it into gear, you move it into gear.
Think of paddling through air and paddling through water
If you have an issue with your GB or clutch I'd dissuade you from installing as it will amplify the issue.
Hope my explanation is helpful to all
Edit: Why would I let it go? Seemed a good idea at the time when I got home. I went OEM and the GTR feels less of a race car
although I am having second thoughts - hence why I haven't bumped it up
I checked the price on the Nismo shifters to price mine - Oh my son of rajab
