Z1 Motorsports Adjustable Transmission Mount Coming SOON!
 

This is just a teaser of another Z1 Motorsports product that will be available very soon!

Following the successful release of both the Solid Aluminum and Urethane Motor Mounts, Z1 Motorsports is proud to announce both a Solid Aluminum and Urethane Transmission mount. Featuring a completely 6061 Aluminum Body, both the Solid Aluminum and Urethane models are lighter than their stock replacements. Just like the Z1 Urethane Motor mounts, the Z1 Transmission mount is both rebuildable and height adjustable.

Tested by both SFR Enterprises (Pirelli World Challenge) and Doran Enterprises (Grand-AM) Teams, the mounts have proven to withstand the harshest enviornments and abuse that the track can only deliever.

The Solid Aluminum mounts shave a total of 1.1 lbs off while the Urethane units weigh in at exactly 1 lb under stock weight.

A key feature to the Z1 Motorsports design is the ability to switch from either Solid or Urethane bushing materials without requiring the replacement of the entire mount. If the Urethane is too soft for your liking or you want to transition to a 100% rigid drivetrain setup, then simply swap our the bushings. In addtion, another distinguishing feature of the Z1 Urethane Transmission mount is the ability to decrease or increase the mount's stiffness. This is done be decreasing or increasing the pre-load placed on the Energy Suspension Urethane Bushings.

The 370Z has a notoriously soft transmission mount. The OEM mount can easily fail when exposed to heavy or extensive track abuse. The excess movement allowed in the driveline by the stock mount results in a loss of power delievered through to the back wheels.

As with any Semi-solid or Solid Aluminum mount, additional NVH sould be expected. The severity of the additional noise or vibration will depend on the model (Solid being the worst).

Prices will announced soon. Be sure to look for these at the 2012 Z Nationals!

Manual or AT?

G37sHKS,
Very good question! This mount will fit both Manual and Auto models of the G37 however it will not fit the AWD's due to a different mount design being present.

In

Have you been able to measure the amount of NVH? Or at least compare it to another Urethane mount such as motor mounts?

Zat_Zuma,
In terms physical data we have not. Just by going by the completely UNscientific "seat of the pants" unfortunately.

We have not compared our mounts to any competitors mounts unfortuantely.

The Urethane model will insulate the noise like the OEM bushings do. The only side affect of the Urethane is the fact that the material is fimer. This will transmite increased vibration into the chassis (driver's compartment).

The Solid models will increase ALL noise significantly. If you want the hardcore track car experience....then the solid is for you. Drivetrain noises, whines, etc. will become much more prevalent. The vibrations and unnoticable rattles will also become much more evident.

I do, I do! Maybe I will have you install them after Znats, since I plan on leaving the car there for other work anyways.

Awesome!

Saw these in person on Thursday. Very well made just like all z1 products.

Of course all Z1 products are well made :tup:

I'm just thinking that with GTM's Urethane motor mounts and Z1's transmission mount, it isn't going to matter how the Urethane transmission mount NVH is ..... it's going to be noisy and vibrate a fair bit :p ......looking forward to it

Thanks for the answer and I'll put this product on my winter shopping list.

Dustin, what's the latest with these?

I just finished a day at Laguna Seca, and these would have been nice (I want the urethane ones!)

We actually received a batch of these last week from the machine shop. Pricing is set at $198.00+S&H for the Urethane and $225+S&H for the Solid Aluminum model.

Again the models are interchangable. The only difference in the two models is the bushing material. If you choose to purchase the Solid or Urethane now and want to swap out to the other model, simply purchase the bushings and swap them out. We will have the bushings listed seperately for sell as well.

Here is a link to the Urethane Model:

Here is a link to the Solid Aluminum Tranmsission Mount Model:
Z1 Motorsports 370Z/G37 Solid Aluminum Transmission Mount

Ready for shipping! Check out Dustin's links above for more information on these items.

How much NVH should we expect for the urethane one? I installed a competitor's product And it was absurd how much the car shook! Compared to stock, how adjustable is it?

Thanks! I have high hopes:)

With our design there are a few ways you can adjust the mount to fine tune it to your liking. The primary adjustment is for ride height. If you lower the engine mounts or need to get a little extra clearance around custom exhaust/intercooler piping, you can lower the transmission. This will tilt the engine backwards unless you have adjustable motor mounts.

The second form of adjustability only applies to the urethane model and does impact the firmness of the ride quality. If you disassemble the mount and add a spacing washer inside of the Upper Bushing (between the Lower Mount Plate and the Upper Body), you can release some of the pre-load on the bushings and lessen the firmness and allow for more movement of the mount. This will incrementally return the behavior of the mount to that closely resembling the OEM Transmission mount.

I will put together some test to illustrate the differences in NVH between a stock mount and the Z1 Urethane Transmission Mount.
