NA / NB engine drop mounts
Thought that some of you guys would be happy to know that we're working on engine drop mounts for NA / NB.
Should drop the engine right around 1/2"-9/16" which sets the oil pan right about flush with the bottom of the subframe, we'll have them available in the standard durometers of 70A, 88A and 95A.
PT racers will be happy to know that this is a ZERO points mod
Should have pics of the prototype in the next couple of days.

Yes.
We used the stock mounts as a base line, then yanked them out and fabricate our own.
Not sure if there's a difference on the NB, but we typically wouldn't advertise fitment of a part before we had a chance to verify it.
I have seen slammed / stanced Miatas breaking oil pans, never seen one that actually broke on track or autox...

Blackbird Fabworx NA / NB engine drop mounts
First look at our prototype drop mounts -
This is the low mount standard 70A bushing version, actual production version will be slightly changed because we actually found more weight to remove.
The mounts will be powder coated in the same pearl Gunmetal Gray shown in the pic and we're more than likely to stick with the Black bushings (for all versions).
Driver side installed -
Passenger side installed -
We're also working on another version of the mounts which will lower NVH (most common complaint), pics coming soon.
The mounts are going to be available to order within the next 2-3 weeks, final pricing TBA soon.

I've had my motor lowered for years now. but I just slotted the engine mounts to do it. This is a better solution. I also have the engine moved back now but that requires a lot more modification including shortened drive shaft, PPF, modified hole in the tunnel for the shift turrent, modified center console, and low profile back of head stuff to avoid modifying the firewall.

Yeah, moving the engine back in itself is not that big of a deal, simple repositioning of the mounting bracket flange will easily take care of that part.
It's the _many_ other pieces that have to be customized in order to accommodate the repositioned engine that cause all the headache...
At any rate, this provides the community with an easy bolt in solution that can be installed quickly.

Well aware of it, I was commenting about the relative change if you kept everything tight as you would do if you were just replacing the motor mounts themselves, a half inch drop nets a quarter degree difference at the pinion.

So forgive me if i'm missing the obvious here, but is the only (or main at least) benefit here a lower CG? I've been tracking an S197 mustang for the past few years and just recently swapped to an NB so i'm just reading and learning all i can. Not sure if this is fixing a miata specific issue of some sort i'm not aware of, or if its just better CG. Thanks.

The drop mounts are meant to lower the CoG, but the design offers more than just that.
One of the most common issues you'll run into while driving hard is that the OEM motor mounts (and the replacement "competition" mounts from Mazda) allow the engine to move A LOT.
This in turn causes the engine to torque over so much that when you're trying to shift, the next gear is just not there, causing you to miss the shift you're going for.
By stiffening the mounts you're keeping the motor and trans where they should be, and with the added benefit of lower CoG, it's a win-win situation
