Ralliart Group N Motor Mounts
I recently purchased a set of Ralliart Group N motor mounts from Z1. Has anyone ever installed these before? I need a few tips. After looking around at the stock mounts and their location in the engine bay, I have a few concerns if they will even fit at all. I am pretty sure the top engine mounts on the drivers and passengers side of the engine bay match two of the four mounts I received. BUT the lower mounts are a different story. The front lower mount on the crossmember looks as though the Ralliart bushing will need to be pressed into the stock bushing's bracket? Is that how it is intalled? Or does the bushing just slide out of the bracket? The rear lower mount that bolts to the transfer case and the rear of the engine does not look like the rear bushing I received at all. The stock bushing is actually two bushings that are connected by a welded bracket. One side bolts to the rear of the engine while the other side of the mount bolts to the transfer case. This actually makes this mount two bushings that need to be replaced in one bracket! I only received four bushings since that is all Ralliart makes for the Evo 8. Can anyone help me out a little with this? I am thoroughly confused. I am not sure if these bushings will even fit! I have searched, but have only found a handful of threads about this, and not a single post has any how-to whatsoever.
Thanks!

I looked at the bushing thing and decided it was too big of a PITA so I put this in instead.

BMan-Can you please remove the image? We are all aware of the Weapon R Engine Dampner. This thread has nothing to do with what you posted.
I took pictures this morning of the mounts. Unfortunately, in a rush to leave I left my camera in my garage where I took the pictures. I will post them tomorrow morning I promise! I found this image though: http://www.performanceautowerks.com/...age.php?pID=32 These look just like what I received.
I couldnt find out anything about these mounts before purchasing them. I hope this thread will help everyone in the future! I plan on doing a lot more research on engine mount solutions. I will have a solution to this problem one way or another!
The rearmost mount seems to me like it is the culprit of everyones problems getting the shifter into second gear. If you're really in the know when it comes to this kind of stuff you will know what I mean. Simply replacing part of this piece will not fully solve the problem, and I plan on trying to make this mount even more solid. More to come on this!
I attached pictures from the Service Manual of the engine mounts in case anyone cares to see. The first picture is of all the mounts. The second shows the mount that I think is the biggest problem. It is labeled as 10 in the picture. You can see that the entire drivetrain will rock back toward the firewall as the car accelerates. The small bushing end of that mount is what keeps the entire drivetrain from moving under acceleration. This is the mount imo that needs to beefed up considerably.

I had Deyeme Racing motor mounts in my 3rd generation Eclipse before and they were a nice set of replacements. If you're going to set up this deal with them, make sure that they know what durometer polyurethane they will be using. I remember they used to let you have a combination of stiff and flex levels.

kmxxbadboy-Are you the guy who had Deyeme fill your mount? Or are you the guy who bought the other set of the Ralliart mounts from Z-1?
I think I have changed my mind about Deyeme Racing filling the mounts. I was under the impression they removed the stock bushing completely and fill the hole with poly. Well, they do not do it that way. They partially remove part of the rubber bushing leaving a little left to hold the sleeve for the bolt that passes through the center. I do not think this is the solution I am looking for.
Heres what I am thinking: I will use all the RalliArt mounts since they are so firm. They are actually a very hard durometer rubber. See the pictures I posted of these to see how they arrive to the customer. Very Nice! I am glad there is a replacement out there, but IMO its not a complete solution to stopping the drivetrain movement. That still leaves the rear mount with one small stock SOFT rubber bushing.
I could have a fabricator make a steel sleeve that will replace the small bushing in the rear mount. Does anyone think that would be too harsh? I dont think it will be much of an issue to me. I just think some may find it too harsh for the street. I have attached a picture of the rear mount with the part of the mount in question circled in red. The mount is labeled as "10" in the picture.
Or then there are these options: This mount could be beefed up by using a aluminum or steel sleeve to replace the bushing. Or maybe someone could CNC a nice solid mount that would require the customer to press in the Ralliart bushing at a machine shop. One end being solid, with the other end appropriately sized for the Ralliart mount. Another option would have the small end of the mount machined to accept a polyurethane bushing (size yet to be determined, but I think something close could be found here http://www.energysuspension.com/pages/sk_bsp1.html ) with the Ralliart mount on the other end of the mount. I am not sure about using a poly mount on one end with the rest of the engine mounts being hard rubber. Wont there be some kind of harmonic differences in the different materials in the mounts? I am no expert on this subject, I am just theorizing here.
There are several manufacturers now making mounts similar to what I am descrbing. See this webpage for what I mean: http://www.vf-engineering.com/ffengmount.htm These mounts use poly on both ends however.
Then there is the problem with the front lower mount's bolt. See this thread to understand what I am talking about: https://www.evolutionm.net/forums/sh...d.php?t=106238 I need to have a fabricator make a sleeve to fix this at the same time they are making the rear mount. This will greatly reduce engine movement also!
Opinions welcome! If no one cares about this then I will find a fabricator near me to make one end of the rear mount solid somehow or another along with making a sleeve for the front lower mount and be done with it. If there is a demand for these, then maybe a Vendor on the board can step up and help me out. I would be more than willing to work with someone very closely on this so that we (Evo communtiy) can have a solution to this problem.

Hey Al-DynoFlash: When you installed these did you also replace the small bushing in the rear mount or did you just leave it alone?
Personally, I think it would be a waste of my time and $ to just replace 4 outta 5? It kinda defeats the purpose of doing this imo.
I hope maybe one of the Vendors can step up here to offer a little fabrication/machine work. Is there anyone on the site that has the equipment and time to make a pair of steel or aluminum bushings/sleeves to solve the two problems I have mentioned in this thread? Theres not alot of places in my area (I think) that could do what I am asking.
Thanks!

Yeah i would like to see some better pics. I have been looking for somthing like this also but really havent found anything that pleased me. So i was going to buy some urathane and just fill the stock mounts.
If you can possibly open the packaging and take some pics maybe that can help. I got everything out right now so i can get a good idea about what you are talking about.
