This write up is pretty short, because there is one main question everybody asks about the solid aluminum mounts…
Q; “How much does the car vibrate with the solid mounts?”
A; Its not as bad as you would think-
On a scale of 1-10, one being the same as ‘OEM’ and 10 being ‘extreme vibrations’…
-At idle there isn’t much difference between OE and Alum. (Scale rating-1)
-Under normal acceleration you can tell the car seems more in tact, like an undercover race car. (Scale rating-2.5)
-When you are accelerating fast..aka flooring it it’s solid, not crazy vibrations, but enough to make you a little giddy (Scale rating-7/8)
-When drifting, it feels smooth while in motion but stiff, it was a little different initiating at first because you can really feel everything. (Scale rating-RACECAR)
Things that I wasn’t expecting before these were installed-
The biggest unexpected difference was the noise. It transformed the inside of the car to sound like a cockpit of a racecar. It was noticeably louder as if I had swapped exhaust.
The engine sounds echo’d quite a bit more also, I thought something was mechanically wrong at first. All the noises that I was used to before weren’t the same. Since the vibrations used to get absorbed into the rubber engine mounts, it would mask the noise. Now that that vibration has no where else to go you can really hear it…it’s awesome.
The solid transmission mounts made shifting feel sturdier also, more precise than before.
I WOULD recommend the solid motor and transmission mounts to anyone that wants to stiffen up their Z, anyone that wants to really feel their car, and any Z enthusiast.
I WOULD NOT recommend these mounts if your looking for comfort and an ultra smooth ride… if thats what your looking for, get a Lexus.
Information from Z1 about these mounts;
Solid Aluminum Transmission mounts;
A direct replacement for the OEM Transmission mount found in both the Nissan 300zx and the 240sx, the Z1 Solid Aluminum Transmission Mount is THE LAST transmission mount your car will ever need! Machined from 6061 Aluminum, the solid transmission mount will never sag, wear out, tear or rot. By installing a solid aluminum transmission mount, 100% of the engine’s power/torque is channeled into the drivetrain and suspension. This equates to improved performance on both on and off the track.

Both lighter than stock and much more compact, these solid aluminum motor mounts are available at a fraction of the cost of New OEM Nissan Motor Mounts.
