Has anyone tried one of these transmission mount inserts from revshift ?

If so, is it worth the $50, and do you need to remove the trans mount from the car to install it ?

also, any more noticeable vibrations ?

Thanks.

Alright, you got it. I've been putting it off for long enough. I already have it designed. I guess its time to make a real life part. There will be no competition. :D

Do you want a better toe rod option while we are at it?
I'm excited about the transmission mount. The rubber on my stock mount is starting to peel away from the metal. But the Revshift insert looks new. Any chance it'll be height adjustable (e.g. screw drive) or provide better lateral support? Also, what's the chance that you could mold some 80A exhaust hangars? The OEM rubber ones are very soft and can crack and decay.

As far as toe rods go, I think you'd have to come in with a product that's lighter, stiffer, cheaper, easier to adjust, or some combination thereof (versus BMR or Creative Steel). On the front end of the car, there's more room for improvement--we don't have light/stiff tie rods, and we have one of the world's heaviest spindles. That spindle could be swapped out (see thread) for the V2 spindles, if only we had compatible sway bars or end links. If there's anything you can do about any of that, I think you'll have some excited customers.

I'm also looking for someone to do some plastic/carbon fiber molding of underbody panels. Do you know anyone who might be capable and interested in that?

How about a 80a guibo joint? One that can be a solution for the majority of misaligned drivetrains....

Absolutely agree. I have the Revshift billet coupler, and cannot run above 21 mph with it (the driveshaft carrier bearing vibrates in a truly horrifying way), despite doing all of the other bushing modifications, and following the instructions to the "T". In my opinion, the OEM drivetrain geometry makes it impossible. I'm saving the coupler though--should be able to use it when I get the G-Force 9" IRS.

Now that would be awesome and worth every penny!

I wont say specifics right now but you will be happy with it.

There is an 80A full poly indestructible guibo in the works. We are waiting on patents. Yes, its that serious.
How far away is the transmission mount? I'm ready for one!

I know the answer is likely no but I have to ask - any ETA on the guibo? I would love to get another year out the driveshaft before going to a 9".
How long is the moonlighting period for the vibes to stop or go away when using the insert?
It's giubo! Not guibo :p lol
THe more improvements on the drivetrain I can get, the better. Keep us informed on what you are making! :)
I'm almost done installing every single revshift product they make for my V. The GF 9" rear is pretty nice but still has a clunk, although not anywhere near as bad as the stock diff.
We will see how the GIUBO works with the 9" IRS and 2 piece driveshaft (the current billet one)
I have installed new motor mounts,rear diff. bushing,trans insert and finally shifter bushings. It seemed with each replacement the shifting was better but more cabin noise and vibration each time. I was getting some serious shifter rattle and gear noise so I took out the Revshift insert the other day. I trimmed down the high spots on the top and bottom and stuck it back in there, maybe 3/8" total material trimmed off. I also took maybe an 1/8" of the sides were it touches the OEM rubber. I was basically wanting some height from the insert but not wanting it to be crammed in there. I wanted to give the OEM mount some room to move around under load if needed. So far it seems to be my fix, gears shift smooth and just a hint of gear noise under heavy acceleration. Under normal driving, no gear noise so far. I also was concerned about maybe it slipping out, after several hours of driving it hasn't moved.

Installed the Revshift trans mount over the weekend. So far so good, tad bit tighter between shifts. I have a B&M shifter which is already a bit noisy but not bad. Now under acceleration it's much louder in 1st & 2nd. Not very happy about it. May look into PISNUOFF's shifter next.

I felt the same way. It helped the shifts, but was louder.

Creative Steel complete replacement mount was the best of both worlds for me.
How does that one help with the lateral movement of the tranny on turning if just the bottom of the mount is reinforced. That has been another concern of mine with just the insert. If the factory rubber is that squished then there will be some rolling around wouldn't there?

I am looking to upgrade to the RevShift full trans mount when done. ready to ditch the last CS piece I have.

I'm sorry verywhitedevil that you feel that way, that's not what we're about. Let me know if there's something I can do to change your mind.
The more I drive around with the Revshift trans mount, the more the noise is bothering me. It's only been a few days but frankly the stock mount kept things quiet in the cabin. Seems like you need to find the right combinations of mounts to get happy results. I'll give it a few more weeks and see if things change, otherwise I'm removing mine.

I have the latest and greatest CS mount and all has been well. Made some modifications of my own to my hurst shifter to get the noise level down. I also got a revshift insert that I will try when I swap the clutch simply just for a comparison. I have had not a single issue with my Cs mount.

In fact I think CS should hook me up a diff block just so I can try it out haha.

I don't care about past comparison threads but in my car with new CS motor mounts and tranny mount. My car is solid and noise free.

Remember that every cars geometry is a little different. What works for one may not work for another. Take that for what it is worth.

----------

I might add that I have not tried a single revshift product and that's why I got the insert. To try.

I look forward to getting some other bushings from either company. My initial purchase decision will be based on general reviews and hardness of what I'm looking for. Also I appreciate great customer service.

I look forward to further enhancing my v for me . Whether it be company A or company B. Or maybe C?

Can't get any more honest than that ^^^

This about sums it up right here! I have parts from both companies, just cant find the right combo yet. Frustrating.
