Update: October 16th 2020. One of the 60A bushings exploded. Not the fault of Innovative at all, I took the set of "250hp" rated bushings and ran them at 400+, and ran them hard. Launches, flatshifts, the whole 9 yards. So my feedback here is make sure you are choosing the correct bushings for your power level, I should have left the black 75A's in.
@thecarpassionchannel same happened to me with my 220hp go getter. Talked to Innovative and they sent me a free upgrade to the blacks. Highly recommended innovative! Thanks Miata Papi 👍
Oh.. didn't see this until after I ordered a set of 60A.. hot side or cold side that exploded? maybe a hybrid (75 on one side. 60 on the other) could work? 🤔
@@Baj79 It's only going to be a possible issue if you're running above the recommended power or if the car sees heavy track use. I can't remember off the top of my head which mount it was, but there's certainly one side that always fails first. I made a couple videos prior to the Tuscon Dragway 1/4 mile where I pull out the mounts, show their condition, etc. If you have time you can scroll through that and see which side it was
@@gsisk911 Alright sounds good, luckily there's only like 100k people that watch these videos so we should be safe. Also, ya probably fly more than me these days!
OMG that's a crazy difference. 4hrs to re & re. Installed on the lowest hole. No interference issues. I use to wear earplugs with solid mounts. Every thing in the interior would vibrate. On the test drive I realized that the stereo beeps when you push the buttons. May actually be able to get the wife to come for a drive. SWEET!!!
One thing I noticed with my innovative mounts is that the brackets were actually shipped to me backwards like yours in the video. Don’t know how that happened but I spent a substantial amount of time trying to figure out why my engine would not fit where is needed to be… then I watched your video on them. So I agree, innovative needs a diagram or something included with the mounts
Running the AWR Complete Upgraded Motor Mounts, 70A. You will notice the difference from stock but running a Maruha 87mm crank with double the HP really like these.
I now have AWR's in both cars. 62's in my 260whp supercharged car, and 70's in my 500whp turbo car. They are the only mount I will use anymore, the Innovative's did not stand the test of time unfortunately
Greg, you're a legend. All that work and time for a motor mount video!! it's 100% entertainment, especially at 9:15 with the camera shake and top out-takes too. How can anyone give this a thumbs down??? ¦:¬\
I guess Im asking randomly but does anybody know a method to log back into an Instagram account..? I stupidly lost my password. I would appreciate any tricks you can offer me
@Harlan Christian I really appreciate your reply. I found the site thru google and Im trying it out now. Looks like it's gonna take quite some time so I will reply here later with my results.
Thank you Greg for the awesome review and promo code - I ordered them today, one of the first updates on my NB Miata besides all the regular service parts! You are awesome! Please keep making more Miata content, I am learning a lot!
Thank you for your time on testing these! I've been wanting new mounts as my MSM mounts are obviously worn, just wasn't sure of the higher end options. I like comfort!
Awesome review Greg! This video came out just at the right time. Just ordered a set for my Itb miata with your discount code. Pretty much covered the shipping!
Man Greg this one was a lot of work! 3 Motor mount options and I appreciated your experience and opinions! I have the AWR mounts now and the NVH is a bit too much, I LOVE the way it drives with them but the amount of vibration is just obnoxious! I'm very interested in those Innovative 60dm mounts now!
You probably want to put a locking nut, a lcok washer or at least threadlocker on the through bolt. As much NVH as the BP produces, that nut is likely to find its way onto the highway in short order. You'll likely have to go with a longer bolt if you add a locking nut or lock washer.
i currently have 80A mounts in my MX-5 and never again, i tell you. going to swap them for something more civilized when i get different set. in cold weather the car vibrates like crazy until it gets up to temp :D
IDK - I'm not a fan of these types of mounts because I feel like there is a hinge effect, where the torque axis of the motor (along the crank) forces these type of mounts, that have bushings connected by a bolt along the axis to swing like a hinge. The video sort of proves my theory because every mount showed the same amount axis rotation, but they did differ in vibration because that is related more to the actual bushing hardness. Why re-invent the wheel? Just go with Jaguar V8 bushings designed for higher torque at about 1/10th the price of these custom pieces. The Jag bushings bolt right up to the stock Miata motor mounts. A lot of racers run these.
Just a minute in, those "scalloped" holes look a little sketchy, for the tension side. Speaking of which, I'm wondering what you think of a hybrid set, using stock or "close to stock" (whatever that means...) on the compression side.
@jsr462 I used the Mazda factory rubber mounts 40% stiffer or so. It feels good at first, light increase in NVH but it fades completely away about about a week. The performance enhancement over the factory rubber mounts is existing but definitely not for track use IMO. If you autocross / canyon drive the car with factory power levels, you're probably fine with a 1.6l and the MFC rubber mounts. But IMO if you either 1) race on a road course or #2 have any power adders on your car, the factory mounts 40% stiffer didn't cut it for me personally... After about 2-4 weeks I was missing shifts again. Not as bad as before but still not great. Then I got the AWR mounts right after I boosted the car. The NVH is pretty severe but could be a lot worst. After a few months of driving on the AWR mounts, and especially this past year, I still have major trouble with the 2nd to 3rd shift for some reason... Sometimes it's even hard to find 2nd from 1st... I'm at 190wtq/220whp on a 1.9l GT2554r Also running Delrin Diff bushings with the 70duro AWR engine mounts you'd think I should be fine. But I still seem to never make 2nd - 3rd whenever WOT it misses about 9 out of 10 times... so IDK.. I'm getting to the point where I might try and custom fab a tranny mount to keep that flippin shifter where it needs to be!? Good luck out there yaw lol
So far, the 01-05 is not mounting properly on Driver's side. Dipstick does not allow the mount to sit flush on the block and will NOT bolt up. OEM bracket has notch by dipstick that allows it to bolt up just fine. Design flaw. 01-05 guys, including MSM, be aware.
I have video of me missing third gear in three different angles. The wonders of shot standard engine mounts. Replacing them is on the short list of things that need doing.
Would like to see the side by side engine bay footage between awr 70 and innovate 60s. Either way it looks like I know where I'm getting my mounts from.
havent used either one of these mounts, currently around 230wheel probably and the mazdaspeed mount are 100x better than the stock mounts...doesnt even feel like it could be better, but who knows
What's the cost difference between insert replacement? The one thing I will say about my AWR Racing Inc mounts is that the inserts are readily available through a few different suppliers. Last time I ordered replacements it was $15 for a set of 4! Which is pretty good compared to replacing the stock mounts and one of the reasons i went to full poly engine mounts.
@@innovativejoey1826 It's a shame you dont make anything for my car. The only high quality mounts available are AWR. Nothing compares for the 93-97 Mx6.
Use hydraulic pad mounts from volvo 940 turbo, my car has 550whp/700wnm and still running original stock mounts. no noises, no vibrations and they keep engine from twisting. I have 5mm clearance between my intake manifold and front strut brace and it has not been touch it. For comfort and rigidity they are about perfect? for size they should be able to fit miata with custom brackets in subframe and block
and moving the engine mounts "pivot" points more apart from eachother they will keep engine from moving around with softer bushes. in volvo the distance between mount bolts is around 65cm where the "pivot" points are.
Need to get some for my Eunos. It's only a daily but I hate the feel of the engine rocking around. Got Vibratechnics in my DC5 and are great shame they don't make kits for miatas
Did you test the awr mounts with new bushings to level the playing field or did you use the ones you've been doing 400 hp pulls on for a few months now?
Dude, not to be creepy but I noticed that you parked next to my nb miata. It’s the weirdest thing since I was just watching this video lol right by el super on university
i dont know if its fair to compare those old many times abused awr mounts with new mounts of other manufacturers, to make it fair the awr ones had to be new also..
@@TheCarPassionChannel are these the old awr bushings or the new larger design ones? because that might make a very big difference! the new ones with the larger bushing might be in a sweet spot between the innovative 60 and 75. and better rated to handle the horsepower as well

Hey i have a 1994 mazda miata and i did a compression test on it and to do this i unplugged the cam angle sensor and after i was done a plugged it back in and started the car up my rpm is half of what the car actually sounds like
6:35 haha true words ;D I tried to do the coolant reroute yesterday, when the second screw of the thermostat housing instantly snapped in half :/ Any CPC pro tips for fixing it or shall I just drill it out and tap a new thread?
Just did the innovative 60 mounts on my 1.6 miata. I can't find the torque specs for the long bolts that go through the bushings... could you give me an idea of what you torqued your to. Thanks!
Hey King, I’m purchasing some mounts at the moment and can’t find any info on them. I have a VVT 96 NA8, did you use the mounts suited to the car or engine? Cheers
Do you think the height on the innovate mount could be adjusted while on the car? Take the center bolts out, jack car up and then re-insert? Or would that be too hard to align everything?
I have those and I love them. No increase in nvh that I've noticed, but I also know I have a miata not a Bentley. Motor stays in place and makes shifts alot easier

Great channel guys. We just met a Miata owner and interviewed them on our channel which then lead us to your channel! Enjoying it.
