Car is a 98 Honda Civic EX with a B18B1. Currently have prothane poly inserts in my three primary motor mounts, but the two torque mounts towards the very front of the car on the bottom of the engine bay are pretty much destroyed. I was going to window weld the two mounts, but people have told me they are not needed with polyurethane motor mount inserts. Is this true?

 

Yes, they are. They prevent rotational movement, which is bad for your axles, transmission, and rotating assembly. OEM will do the job, but solid mounts will do it better. Solid mounts will also transfer a LOT more vibration to the cabin. Not fun for DD. Ask me how I know.

 

Lol. Are you a 90 year old man? Do you think your solid mount civic should ride like a Cadillac? I've run energy suspension inserts in just about all of my daily drivers with not one complaint. You will forget they are there after a day or two. Really not that big of a deal.

 

Has it been so long since you've driven a stock Civic that you don't remember what it feels like? Do you know what anyone on this forum besides yourself wants? Do you know the difference between solid torque mounts and poly inserts? If you want to try to act like the big man, come talk to me when you're running solid billet mounts all the way around.

OP, if you want to beat the **** out of the car on the track, get some solid torque mounts. If you just want a comfortable DD, get some OEM replacement, or HardRace torque mounts.

 

The front torque mounts are required even if you have aftermarket ones like from Hasport.
In fact if you call Hasport they will tell you that you still need to run the front torque mounts.
Avid makes a decent set not to terribly hard on the wallet.

 

I have a 100% stock 97 civic and 98 integra type r if you really must know. My previous daily drivers had inserts on the stock mounts. I am hardly trying to be a "big man" but your reply would possibly sway someone from using inserts on a dd which I think is rediculous. And no, I have not ever ran a true solid mount.

Remember that this is a public forum. With the in mind there will be different points of view and different opinions. If you aren't open to the idea that people will not agree with you all the time, perhaps you should stick to just reading posts and keeping your opinion to yourself.

 

im running avid torque mount on the tranny side, k-tuned traction bar with engine mount, innovative engine mounts, and now that the mounts have a few kms on them, the vibration isn't as bad as it was when I first installed them.

I have 1 Avid torque mount for sale if anyone is interested. They really nice quality pieces, and definitly keep your motor in place

 

A good rule of thumb is that an engineer will not design a part for a car without knowing exactly why it is needed and then they design it for the type of loads and environments that part is likely to encounter, and after that they design it to have as few negative consequences to the occupants of the car as possible.

They serve the purpose jbpnoman stated, and they also do it in a way that does not transmit large amounts of engine vibration into the passenger compartment (and really the whole car). Stiffening them or welding them solid will allow them to do their work, but at what cost? you are going to feel every vibration possible and the inside of your car will sing with rattles before too long as a result.

Even the Poly inserts increase the vibration, though they provide a service. They give a bit of compliance so you don't feel like the engine is directly connected to your body, and they also protect the factory bushings which are designed to do the job with as much comfort and noise reduction as is possible. That means in short, without poly inserts they break easily. They preserve the front mounts near indefinitely, as they cover them from even contacting air which is harmful (O3, Ozone). They will likely never fail. BUT...

The poly inserts introduce a high frequency vibration which at first (at cold start) noticeable in the dashboard, I only have my front two in at the moment and they do cause extra vibration from stem to stern.

In the end, it's all the little things we do to stiffen up our cars added up that make them ride like they're trying to vibrate your teeth out and feel like the car hit a 3 inch pothole when it only went over a freeway expansion joint.

 

Decided to go ahead and order some oem mounts from majestic honda. Does anyone know if there is a difference between the mounts on a 97 ex and a em1? They are different part numbers and one of the em1 mounts is slightly cheaper. I figured since I have a DOHC motor I might as well get the em1 mounts, but I want to make sure they will fit on my car before I order them.

 

I may even get the hard race torque mounts. How are the hard race mounts versus the oem mounts vibration wise? This is my daily so Im not looking for anything too serious.

 

I have the poly inserts on my daily and aside from a small amount of vibration, the effect is
negligible. I would assume full race mounts are going to transmit even more vibration and
might be a bit much if this is going to remain your DD.

 

I've go the whole Hardrace setup; motor & torque mounts. Highly recommended.
