Transmission and Motor Mounts?
 

I just had a question for those that have upgraded their mounts to polyurethane mounts like offered from Z1. Did you notice a difference in power transfer and was there added noise after the install? I was thinking of getting these, but wanted to hear thoughts first. Thanks.

Id also be interested in an answer to this!

The answer is obviously YES.

There will be more NVH transfer into the car and less driveline slop.

I'm ordering both of those this weekend. Along with another long list of mods. I'll have to see who carries all that I need. Unfortunatly one shop does but the communication level is nonexistent.

I have all new Z1 polyurethane mounts installed even the transmission mount to and yes there was a noticeable difference in vibration but when I step on the gas the flexing of the motor is almost non existent now. I love the mounts. Just my thought on it. I recommend them to anyone.

Does the shifter still move under acceleration with these mounts or does it stay in one place better?

I'm sure if any it's very little. Think racecar.:tup:

It will stay more stationary, but this would be basically the worst reason to buy them. For the record.

I am sorry I can't answer that I have the 7at. I love these mounts and swear by them and every car should have these mounts. Trust me you will see a difference in everyday driving. The noise and vibration is not so bad to the point it's irritating its actually just right and when you take corner and launch that's when you see the performance of the mounts come out. I love theses mounts in my car

I keep thinking about these. The problem is, I put hardened engine and tranny mounts in my last car. I loved them for the first year or so. Sixty thousand miles later I was kicking my own ***.

You kick your own a$$ after 60K miles? Sure is a long time to make a final judgement?

I just ordered solid motor mounts and the poly trans mount.

Yeah, after driving it to work for several more years, I could have done without the hardened mounts. Mainly when the ac was on.

Drop Engineering also has some very nice looking mounts. I believe they only use a 70A durometer bushing which isnt TOO terribly stiff, but will make a world of difference in the power transfer through the drivetrain.

Just another option for people to keep in mind.

I had the Drop transmission mount and it was WAY too stiff for anything other than a race car.

I now have the Z1 Urethane trans mount, and it's fantastic. Yes, it does transfer more vibration and noise into the cabin; not so much that it's obnoxious (it passes "the wife test" for me anyway), and as it breaks in it normalizes a little bit. I daily drive my car, and I'm pretty happy with it.

The increase in system throttle response is definitely noticeable. I regularly track my G37S Coupe, and the benefits really shine at the track. I highly recommend it.

Were these the ones that a forum member bought and they self destructed almost instantly?

Yes, http://www.the370z.com/engine-drivet...ion-mount.html

I have the Z1 mount. Can't say enough about it. Over time and use the oem mount with become more soft. The Z1 mount gives a sharper response over the oem. NVH is little but passes the girlfriend test - as in she didn't even notice.

The motor or tranny mount? I'm very tempted to grab the tranny mount, but the motor mount is apparently a bitch to install with turbo plumbing in the way.

Tranny. Easy install too once you get under there.

Definitely thinking about new motor mounts . . . I noticed Z1 has both the polyurethane mounts and solid aluminum mounts . . . anyone recommend one versus the other? I'm thinking that the aluminum should have awesome power transfer, but excessive vibration . . . . the polyurethane seems like it would be a good compromise . . . . anyone have any insights? Thanks!

I have the poly. All the 370Z race teams use the poly. So that made it a easy decision for me.

I really like my Z1 transmission mount! Smoother shifting since there is less movement of the tranny.

I have the Z1 Urethane Motor/Trans (7AT) mounts in my car. There is a noticeable difference on how the car plants the power now.

The car will not shake its self to death after the install. However, the car does tremble a little bit at idle. I really don't mind because it makes me think that the car is shuddering with power and ready to spring alive.

Bottom line - Would I do this again? Hands down, yes.

Who makes the most narrow solid engine mount for 370z? I have Z1 semisolid now but need something even narrower? Need to clear some things in current build so need narrowest solid mount I can find. Any ideas on existing mounts? I guess worse case I can have some aluminum custom machined but buying existing set would be nice. Are the Z1 solid mounts more narrow than their semi solid mounts?

As much as I hate to even suggest such a thing, GTM's mounts for their SC kit may be what you need. Whether you would get them after placing the order is a whole different question.

I've done solid diff mounts, nothing has changed. feels and sounds the same. But in a WRX I did poly motor mounts and cold start up would knock your teeth loose. If it means anything I plan on poly motor mounts again but solid tranny.

yeah full poly Z1's here motor trans and poly diff and yeah it's loud, cant wait to do the subframe and make it even louder yay

Polyurethane mounts always > rubber POS OEM mounts...
Why is this even ???? :confused:

GTM (GET THAT MONEY). Get no product.

What the benefit of the Engine Mount and would it be a better suit when the car is Forced Inducted?

Less worry about it failing, less movement if your turbos are close to the frame, quicker and more efficient delivery of power to the wheels by eliminating drivetrain misalignment and twisting that absorbs hp. In some cases it can actually make the car stiffer by using the engine to brace the crossmember

Thanks for the response 1slow370. However I am Twin SC. Would that make a difference? I am asking as I've purchased the set from Z1 (Poly Urethane Engine Mounts) and I was looking to have them installed this weekend in my G37x AT.

Mind you it is pricey to install the bit** cost is comparative to installing Headers. Do you think it is worth it?

I think u are awd and u have different mounts and they wont fit

Well just so you know the Z1 Motorsports 370Z/G37/R35 Urethane Motor Mounts fits the AWD model.

I just want to know if this is a worthy mod to invest in and
does it help to Put the power to the ground more effectively?

If you have a manual transmission the biggest benefit from stiffer trans mounts is that your shift gates are consistently in the same spot each and every shift whether under load or not. This makes it much easier to shift smoothly especially when on a track. In The bmw e36 crowd this was one of the best mods to help prevent the "money shift".
