I have had my TTR upper engine mount and RKSport lower mount in my 2001 z24 for about 3 months and the car vibrated like crazy. I have heard a lot of people on here talking about the same thing and others saying they had no problem. At first it wasnt sooo bad because it wasnt my daily driver then the daily driver died and the vibrations just got annoying then I turned on the AC and i just couldnt deal. I read about people saying that it is the lower RKSport causing most of the vibrations so I tried removing it and low and behold it was the problem. Just thought Id share my 2 cents on the subject. Id say about 90% of the vibrations are gone and what is still there is kinda sporty feeling. And I havnt noticed a difference in feel without the RKSport part either. So go TTR for a great product, I cant wait til you get your low vibration lower mount out so I dont have to deal with the vibrations again.
Dude its lower mounts period not just RKSports. I have the TTR lower mount, maybe its less vibrations than the RKSport but its still a ton of vibrations. I think most of us just dont mind. What do you idle at?
You're biggest issue is your car is an auto. If it starts viberating bad with a 5 speed, you just down shift and it mellows out. you don't have that rpm control in an auto, so you'll have a hell of a lot more vibs.

if you don't want vibrations, then you need to do ALL the mounts, engine and trans... When you only do motor mounts and not the trans too, you're holding one side of the drivetrain almost completely rigid and allowing the other side to flop around willy-nilly. Trust me, I've had the same thing happen in the Beetle and the DaFlyinSkwirl had the same thing in his cav.... Do one side, and it practically vibrates the dash out of the car, do em all and many times there's actually less vibration than stock.

To my knowledge TTR has not released their lower mount yet. im pretty sure of it. since the testing starts next week. he sells some on his site but i dont think any of them are actual TTR ones yet. Be on the look out for them though.

Actually, the one we sell now is the Prothane/RK Sport lower mount.
We are coming out with a lower mount that should have less vibs, just like out upper, yet be very firm

I stand corrected... sorry guys.
Guys.. I have done full engine mounts to my car using the upper insert, and RK's lower and I really have to say that engine mounts aren't everything they're made out to be. Having a 'better' TTR mount doesn't ensure you get more out of it. Frankly, as far as I'm concerned.. They're a total gimmick that belongs between the intakes that cost over $100, and the throttle body spacer.
I have first hand knowledge on my own vehicle to back this up:
If you have installed your upper mount insert correctly, and your stock lower mount is in good shape your engine will not move. There's no reason to get a solid lower mount if you're already being held steady by the upper. It doesn't matter how many after market mounts you install. Seems redundant to do more then you have to and after all.. They're still just an engine mount, and it's probably one of the worst ways for someone to spend money. Unless your pushing some major modifications that would be beyond the holding power of the lower mount specifically there's really no need to do more then an upper insert. Steady is steady no matter how you slice it, and since this can be accomplished by a simple insert I would advise against spending more then that.
I seriously don't understand why more people don't come out and say this.
The bottom line is that I have had both upper and lower mounts on my car installing the upper mount insert considerably reduced the amount of engine movement in the bay. So much so that by installing the lower mount there was absolutely no change. I'm not anti-vibration since I rode with the lower mount in for about 40,000 miles only because I bought it, and decided to use it since I bought it and used the resonation from the mount to listen to the engine, and gauged my shift points off of the sound. Then TTR comes out with a different mount style. What's the point? Seriously? If you've got the money then great.. More power to you I guess, but there's only one level of steady. The engine isn't going to magically reclaim more lost torque due to having a TTR mount then to use one of the solutions that have been around for years. I would consider the TTR something more like a functional appearance mod rather then a 'better solution'.

Matt - The insert over a years time allows movement in the engine. Many have found this, and the VIBS are MUCH more harsh with the insert. The TTR mount has less vibs. Also, the reason for the mount is it allows that engine movement to be transfered to the wheels. If it is a gimick, why do ALL drag cars have SOLID mounts? Same reason, as why we produce this mount.
People don't come out and say this as they realize the benifits to solid mounts, we have no idea how you can think that they do not benifit....
Again, it is not a functional appearance, it is a more functional performance modification than the simple insert.
Many love to smash products on J-Body's, do to lack of interest, wishing they had one and can't afford it, etc, and all you are is hurting the support to these cars, as manufactures are not going to show support to these cars. Instead they will support car groups that respect them, and put support into items they produce.

So, If the vibrations are bothering to people, get the TTR mount for less vibrations. That makes sense.. But stiff is still stiff the only difference between the TTR upper, and stock insert is that the TTR is of course better built, to allow for longer upper mount life. Aside from that, there's still no additional performance benefit. Do you see what I'm saying?

ALL drag cars have SOLID mounts because they have major modifications that would warrant solid mounts.

I didn't say that solid mounts don't benefit.. That's common sense, that they would but what I was saying (perhaps poorly worded) is that solid mounts = no engine movement. So if you can get no engine movement without 'solid' mounts what's the point to solid mounts if you aren't surpassing the holding power of the stock lower mount, and upper insert?

All I'm doing is hurting support? By asking questions, and giving my thoughts on common sense? That's profound.. I hope you've got motive to back up that statement and proove that I would benefit somehow from harming the after market support of the J platform. The same platform that I have been supporting for 8 years. You mean manufacturer's aren't going to show support to these cars if we ask questions that need to be asked? Instead they will support car groups that 'respect' them, and put support into items they produce. AKA just buy every part that rolls out, and don't question it's validity from one person's setup to the next? If I am somehow able to singlehandedly drive away after market manufacturer's then they shouldn't of been producing parts for the J platform in the first place. WE have all had a part in creating the after market support for these cars. It takes love and dedication to the J platform to see past it's original insignificant economy car designation. We should have manufacturer's that share that kind of bond making parts for the J, not some bean counter in a back office showing on a chart that it's economically viable. There would not be a J platform after market without us. I love my Sunfire, and that's why I continue modifying.

I have all the mounts possible. I have the TTR upper, Soon to have the TTR lowe, Control arm bushings, Solid Trans mounts. and everything.
Yeah the TTR parts look good. But in my opinion they work too. I went from bone stock to the prothane lower. still had wheel hop like a mother fu.. the lower alone cut out some. then i got the upper which eliminated all of my wheel hop pretty much. then i got hte solid trans mounts, and control arm bushings. this made all my bushings solid and or poly bushings.
I auto x all the time and for me, wheel hop is bad, engine movement is bad, solid front end is good. so i have everything on there solid. and my lower was like $40-$50 or something. i know i have spent more money on some more stupid stuff. and if it helps me that little bit then its worth it. plus pretty much anything is better than factory GM. Most of us know that.

This one says it all, there is an issue with long term use of the insert, many have found over the years, not only are the vibs bad, but it DOES get sloppy and has movement in the engine drivetrain.
Our improved mount over the insert, has less vibs, has less movement, even after the years, as they have been now out for over 2 years.
In recap you agree solid mounts do provide benifit, and the benifit on these cars are keeping wheel hop down, keeping exhuast down pipes from cracking, and having a better throttle responce as the engine doesnt shift when you step on it.
The insert is a good start, the get the job half done mod (IMO) where we believe the TTR mount benchmarked that unit and surpassed the function of it.

The last 2 posts in this thread have spurned more facts regarding the benefit to solid mounts then I have seen for a while. Minimizing or eliminating wheel hop is an EXCELLENT sales point. Avoiding cracked exhaust pipes, not so much but still factual. I really don't mind solid mounts being available, I just hate it when things get oversold.
I have had my upper mount in for over 4 years now with no sloppyness. How long are people using them before reporting sloppy performance?

i have the insert and lower mount from Carcustoms and have an auto. vibes were bad at first espically when it was cold out.
but now i hardly feel a damn thing. neither does anybody else that rides in the car.
Im a Xbox 360 fanboy...and damn proud of it!!
^^ They don't notice any sloppy play in the insert UNTIL they put in the TTR mount and realize it did have play. We hear this comment ALL the time.

I would say from my personel experience that I consider the roughly $100 bucks I paid for the both RK mounts well worth it. Both my 5spd 01 and 02 z24's have both engine mounts. It made the car feel more solid and sporty. They also made the launch much more consistent and predictable and helped alot with reducing wheel hop. I do not see how you can say it is a gimmick. I have absolutly no vibration that the guys with automatics mention. Perhaps if I had an automatic and had to deal with the vibration I would feel differently.
By the way I bought the RK ones before TTR started making theirs otherwise I would have bought the TTR ones.

Do you actually realize that these mounts cant be oversold as its one of the best mounts EVER made for a Jbody in terms of price, construction, and over quality. Plus the customer service is 2nd to none.
Yes, i do not own this mount but have rode in and drove cars with them and let me tell you wheel hop is eliminated just from this mount.
I have purchased an RK upper insert for 2 different cars now, my first one is going on about 4 years of use in a v6 car - and it's worn out and sloppy. I'll buy another for it because they're cheap, and the TTR mount won't fit... (you guys should mod it to fit the 92 - 96 Lbodies - especially since FFP discontinued business - we need some love).
My Z24 also has the upper insert, but is going to get the TTR mount. My Lbody would too if they made it just because it doesn't wear out. It's also pretty hot looking, so make it fit the Lbody too and I'll buy a couple.

If you can get us the OEM mount assembly we can make it happen, we would like to see about 5 interested though.

What I meant
wasn't that after market mounts are a gimmick and don't work. What I did mean was that the TTR in comparison to say.. The upper mount insert was a gimmick since at the time of that posting my understanding of the TTR mount was just that it was a different way to do the same thing for a lot more money. Which I'm still not completely convinced isn't true since for me there's only one level of steady. If you can achieve that with a cheap upper mount insert it would seem to give the same result as as solid TTR mount that holds the engine steady.
Since that posting we have come to the conclusion (even me) that based upon actual user feedback of the TTR upper mount it does reduce wheel hop, apparently has a better lifespan then an upper mount insert, and does hold the engine more steady in the bay which seems strange to me since mine is solid without the TTR, but to each his own.

Actually, I do realize that the mounts can be oversold. If they are sold as a strict performance gain add on it would be oversold since the price per HP/TQ is high compared to what you actually receive. All be it, nobody is quoting gain numbers since it would be different for every vehicle it would be impossible to say that it reclaims 5HP, or 7TQ so I do give them credit for not outright lying to customers. But as long as you go into the purchase realizing that your buying a solid mount for the balance and suspension benefit, and not necessarily 100% power gain then that's ok. If people are buying solid mounts and adding x number of HP/TQ to their personal power counter they may as well go out and buy a throttle body spacer, tornado intake insert, or AIT resistor mod.
Anyway most of what I've replied to has been settled between me and Turbo Tech Racing either by one of us conceding the argument, clarifying our statements to our individual stances, or just plain giving the benefit of the doubt. I understand more throughly they're intended purpose of the mounts, and I think they understand my concerns. Either way, it's cool for us to hang out together now.

I know they were never meant for as a HP adder. They are parts made to help put down the power better... I now understand what you were trying to say.
its like a posi compared to a one wheel wonder. it doesnt add hp, just puts the power to the ground better.

When I swapped over to the Prothane upper/lower mounts, it was when the engine had 140k miles. At that point, the lower mount had degraded to the point of being unsafe. It seemed a logical choice at the time to go with the poly lower mount.
As mentioned, wheelhop also decreased significantly in my car going with those mounts.
Vibes are actually on par with my Cav w/ stock mounts/bushings.
I'm sorry to bring this back, has anyone installed the polyurethane transmission mounts, and rksport lower mount, without replacing the upper mount. would that cause excess vibrations?
