NEW engine mount products from AWR for the 2016+ MX5. Note there are THREE options: Bracket ONLY, Engine Mount ONLY, or combo with BOTH.
First item in the product picture: Steel Engine Upper Brackets that replace the factory cast aluminum brackets. These bolt to the side of the engine block and extend to the engine mount, see label in the product picture. We have seen several cases of cracked factory aluminum brackets and these steel units eliminate the chances of that failure. These upgraded steel Upper Brackets can be used alone to bolt between the engine and factory engine mount, or can be used along with AWR's upgraded engine mount (details below). Price is for a pair of brackets, both Left and Right.
Second item in the product picture: steel/polyurethane replacement Lower Engine Mounts that replace the factory aluminum/rubber engine mounts. These replacements are constructed using AWR's new larger barrel design with large diameter polyurethane bushings. This design holds the engine in place much better than the factory mounts, and the larger diameter bushing allows more squish than the old smaller diameter bushings, allowing more squish in the bushing to minimize NVH. These mounts can be used alone, bolted to the factory subframe and factory aluminum engine brackets, OR can be used along with AWR's upgraded steel engine brackets detailed above. Price is for a pair of engine mounts, both Left and Right.
These mounts dramatically reduce motor movement for much more precise operation of your shifts and much more direct application of power to the ground....and your transmission will live a much longer life too!
- These mounts have been updated with some minor tweaks so they now fit both ND1 (2016-2018) and ND2 (2019+).
- If you get the FULL set of both upper and lower brackets, the package will also include a heat shield to protect the passenger side bushing from exhaust heat. Important if you have an aftermarket header.
- New design also feature a nickel plated finish on the passenger side upper bracket, for better heat resistance from an aftermarket header than powdercoat.
NOTE: Some pictures show the original prototypes in orange, but production brackets/mounts are powdercoated in silver.
Bushing Durometer choices:
62 durometer is the extra soft option for lowest NVH. This will still come with a minor increase in NVH over stock mounts, but not considerable.
70 durometer is the go-to stiffness for all-around high performance use. Will provide a massive improvement in keeping the engine in place compared to stock mounts, with only moderate increase in NVH. Great for a mixed use street/autocross/track fun car.
88 and 95 durometer are RACE ONLY
Note: if you select that you want the UPPER mounts only in the drop-down menu, you must then select NO BUSHING in the drop-down as well, since there are no bushings in the upper mount. You can only select a bushing durometer in the drop down menu if you're getting the lower mounts which house the bushings.
BRIAN'S APPLICATION NOTES: Note that polyurethane mounts take about 500 miles of use to break in. Even a 'soft' 70 durometer is a big increase in mount stiffness and expect a few vibrations in the dash at idle.
My OEM engine mounts were both broken during an on-street collision that jolted the car. The OEM aluminum ones have a weak upper bracket that can easily crack with too much lateral force. I purchased these mounts and brackets and found them to be MUCH stronger and more substantial than OEM. They are pretty easy to install, aside from two bolts on the driver side that are a bit difficult to reach. The result is noticeably less engine movement and worry-free track driving.
