Group N engine mounts, pitch stop and 5spd transmission mount, I also have some transmission/gearbox bushings from Whiteline and have the Kartboy front and rear shifter bushings installed.
I don't vibrate in my seat at all, but I do pick up a small amount of vibrations coming through the steering wheel when stationary and the air conditioner is running.

I've personally found high spring rate coilovers to be more of a culprit of vibrations and noise.

From memory the price difference between the two is minimal, so no reason for not getting the right part from the get go.
