That's pretty disappointing. And the vibration with the A/C on or near 1000rpm is pretty terrible. As bad as a solid front mount I would say. And you can feel it through the entire car versus just the steering wheel for front mount only. The car sounds like a plane under highway cruising. Constant booming sort of noise. I'm definitely going to try filing down the mounts so its not a very tight fit. If that doesn't work I'm ditching these.

 

I'm not getting this dreadful vibration, but I am using a Torque Solution 70A front rather than the Innovative front Mount. I could also have a much higher tolerance for vibration after years driving a Civic with 85A Innovative's.

 

After ghetto installing the front mount for like 3 weeks I finally "fixed" the fitment last weekend. Before that I didn't have the spacers, the back bolt had that much gap. Terrible I know but I had no time and needed my car on the road without exception.





Thats 7 spacers in the back and 1 in the front. I think the spacers are like 5mm thick each. But at least now the hole lines up rather well without effort. Makes taking that crossmember off much less of a hassle. I also filed down the urethane on the side faces so they're more or less flush with the metal sleeve in the middle. Now it slides much easier in and out of the holder (before I needed a rubber mallet) and I felt it cut down on steering vibes.

Btw driving around with that loose rear bolt was a bad idea. It caused a split on one side of that black fork that holds it to a block. And the bolt holding the mount to the fork was completely loose when I went to take it off.



You can see the bottom edge of the split better in the next pic.



Nothing a good weld won't fix. These mounts are terrible fitment though. Probably next weekend I'll take out the side mounts and file the urethane down on them too. I have a feeling it will go a long way to control the bad vibes I'm having. Although I'm getting used to it....I still would rather not have it. And theres enough of a difference in shifting feel compared to my blox front mount and stock side mounts that I still actually want these mounts in place.

 

I haven't noticed the shifting feel outside of the fact that has brought to my attention the rear diff is moving and clunking way to much compared to the engine. I wonder what rubber is next to be changed out

 

I'm just about done changing all the bushings I would ever dream of changing. Motor mounts, rear diff carrier and mustache mounts, driveshaft carrier bushings, rear toe arm bushings. Last one is rear trailing arm. Only the engine and rear diff mounts posed any kind of tradeoff but those are the ones that made the biggest improvements.

 

Did you notice no reduction in understeer from the rear toe bushings? That's the big claim there right? Did you use the Whitelines and set the alignment afterwards?

I've got a 100k mile car that's got a nasty case of the drivetrain lash so I'm trying to figure out what all to tighten up w/o killing DD ride.

Is there a good bushing review thread I've not found?

 

I noticed no difference in understeer/oversteer with those toe bushings. What I did notice is that under heavy braking at the track with track pads and sticky street tires my car wagged its tail less. It was more likely to brake in a straight line. It probably made it more predictable through the corners too but I'm usually too busy to notice.

Most of that drivetrain lash can be killed with a front mount and rear diff carrier bushings. Especially the rear diff bushings, although that introduced some noise. The front mount introduced steering vibes at idle with A/C. I'd recommend you stop there. Everything after gives diminishing returns. I have a thread on the diff bushings if you look up my threads created.

These innovative motor mounts SUCK! I don't recommend anyone get them. They're cheap for a reason, they suck. Terrible fitment, low quality bushings, and I can't even pull my damn trans side mount off because the mounting plate literally bent. Sledge hammering it off was literally stripping the threads on the studs. After I figure out what motor mount set up to go with I'm going to have to cut them off. Such POS.

I drove foxbear2277's car I'm very disappointed in my motor mount setup. His car is quieter, less vibes, more civilized and yet less engine rock! And perfect fitment. He has the torque solutions side mounts, stock rear mount, and buschur/ams crossmember with the solid mount I believe. It was barely worse than stock but worlds better in terms of drivetrain movement control.

 

Thanks for the great feedback deeman. I just ordered a BLOX front mount.

Here's the links to rear bushing threads; all good stuff. Thanks for the warning about the whine.

Did you get around to installing a PSRS or Energy Front Lower Control Arm rear bushing? On my Nissan FWD it made a huge difference in all things front suspension related. Wheel hop, turn in, steering feel, braking stability...

 

No problem. This forum is meant for this kind of stuff.

I had the blox front mount. It didn't really tame the engine rock as much as I wanted plus had the bad vibes at idle with A/C on. Its ok though does a decent job all around.

I didn't do the LCA bushing yet so can't help you out there. But from what I've heard the stock bushing is already a pretty nice unit.

 

Innovative makes really decent products from my expirience, i had them on my S2000 and loved em.

 

So i'm bringing this thread back from the dead, as I'm in the market for some new mounts and I used the 60A ones on my RSX. Aside from the front mount fitment which was eventually revised and fixed, they were awesome.

Anyone else try these in the last year and a half?

 

Still using the side mounts inconjuction with a TS Front, still living with what I find to be an acceptable amount of NVH with very little engine movement.

 

I switched to TS all around with the rear mount as stock. Much happier, less vibrations, and more controlled engine movement.
