There is something to be said about getting in a car that feels firm. It gives you a sense of confidence and quality in the car you're driving. These mounts drastically improve on Mazda's original equipment. The re-designed mount literally takes a whole new direction when dealing with torque. If you're the weekend Auto X type, expect more predictable shifting. If you're in a boosted configuration, expect less drivetrain slop or that feeling of wheel hop that occurs when your factory mounts allow your drivetrain to flex and "bounce" back into place under heavy loads.
All the way around this is one of the more noticeable improvements to the way your beloved roadster feels. We've personally destroyed 3 sets of OE and Mazda Speed mounts on our NB Miata and as usual, we're now offering our customers something that we trust.
When choosing the bushing duro keep in mind the limited amount of material that's actually being used with this design. 70D will feel firm, in fact we really recommend this for EVERY application unless you're looking for someting with extremely little to no vibration isolation.
For my performance street car build... this product is golden! I will admit the NVH is pretty unbearable at first, especially with the Miata’s already inherent rattling interior, but drive it for about 100 - 300 miles and almost all of it goes away. Moving on from the NVH (which is very much bearable, but I wouldn’t recommend it for the DD Miata’s our their), I combined this with delrin differential bushings from GarageStar and let me just say... my shifter has never been so steady in my life and the shifting... never ever dealt anything better (I’m running a Miata Roadster short throw shifter kit also)! Needless to say, if your nodding the miata for track days, auto cross events, canyon runs, or just adding more power... all the upgrades I’ve listed above should be somewhere high up on your new parts list. Love the product(s) and absolutely love the service and help I got from the guys at Fab9Tuning! Keep up all the great work!

2001 Miata LS Torsen: Daily Driver
70 Durometer Performance Mounts
The Good: These mounts feel fantastic. Shifting is much more predictable, the front end feels as solid as a brick when cornering and going over bumps. The stock mounts feel like a 250lb block of Jello under the hood compared to these.
Add some polyeurethane diff bushings and these motor mounts give the car a very responsive feel when coming on or off throttle. Downshifting and rev matching is a breeze because the motor and tranny are always right where you expect them with no rocking or movement like the stock mounts allow. More engine sound comes through the cabin and feels/sounds beefier even if you're running a stock motor. It feels like the Miata should have come from the factory with these mounts.
The Things to consider: exhaust-side will be hard to install without removing turbo piping or a long-tube header if you have one.
I had to do some grinding to make the driver-side plate fit (not much but it was enough to keep bolts from lining up).
You may have wrestle your motor an inch or so in any direction to get the new mounts to line up, so make sure you have some pry bars and/or a friend to help.
First startup is pretty harsh, had to foam tape a bunch of my dash parts to stop them from rattling. The mounts break in fully after 700-1000 miles and vibration lessens dramatically. Low RPM (~1200 RPM) still rattles my doors and hood but it's not unbearable.
The stupid: I damaged an A/C hose by rocking the motor too far in my attempt to install the driver's side mount without removing my header. Don't be stupid like I was, just remove the parts in your way and life will be much easier.
Install took about 2 hours using a 3/8 ratchet and some extentions. Using a lift and pole jack to hold the engine in place while I removed the oem mounts. Upon first starting the car there is some noticably vibration compared to stalk but it is not abrasive or annoying in my opinion. Unfortunately at idle the vibration causes my hood to rattle against my headlight but this is due to my hood being bent. The overall feeling the stiffer mounts gives the car is awesome! My oem mounts were torn in half. The car shifts smoother, feels more rigid and the front end really feels planted in a corner compared to my torn up oe mounts. I would highly recommend the product along with purchasing from fab9. They are quick to respond to emails and questions as well as shipping!
