This really is a no brainer.

Yesterday I had the good fortune to meet Jim Pierce, Owner of Pierce Motorsport.
As an EX-race driver, he now has a racecar prep shop in Torrance, Ca.
It so happens that he manufactures undercar bracing for various cars.
Sense he also owns a FiST, he has made a Lower Front Stress Bar that connects the front of the lower "A" arms on the FiST.

I have used a bar just like this one but on a non-ST and had never found one that fit the FiST.
After purchasing the bar on eBay I contacted Jim so as to choose the color I wanted, then drove to his shop yesterday to pick it up.

The bars they make are of Chrome Molly, very strong and vary lite, this one only weighs 2 pounds.
Since our cars do not have any additional "A" arm support and the front mount is only a big bolt.
If you are going drive your car in a spirited fashion, I would highly recommend this type of bar.


The install is very simple and only takes about 30 minutes.
You just need a 17mm deep socket a breaker bar as the bolts are tight.
I do recommend that you do not remove both bolts at the same time but do one at a time.







Maybe we can bring Jim on as an owner and vendor.

How does it feel under hard cornering? Any different?

Nice job painting the caliper! And what RMM is that?
Thank you.

I have searched the Ford Service Manuel over and over, also I have searched many times on FordParts.com.
I have even called many dealers and have come up with NO Rear Motor Mount.
Our car just does NOT have one.
There are mounts on either side of the engine and if removed the engine can almost fall out.
Are you calling the transmission end the rear?

Is it possible that you are referring to the Roll Restrictor?
I just want to make sure we are speaking about the same part.

Is this a 4130 "Chrome Moly" (chromium molybdenum) alloy steel, GTAW welded and powder painted? What are the available colors? Does it need a longer bolt, or does the OEM bolt suffice? What is the ground clearance after installation? This looks like a well made bar. Does it increase roll stiffness? Is local pickup allowed?

Very interested in this upgrade.

Black would be great.

Is Pierce going to make more?

Almost any color is available.
This is one of the best pieces you could add to your car.

That is referred to as a Roll Restrictor in the service manual.

Mine is from Steeda.



Dave
LOL

Unfortunately, it has become a slang/term among Fiesta ST forums to use "Rear Motor Mount". Now we have "Engine Support Rod" and "Roll Restrictor". But glad to know the proper name.

Thanks for the info on Steeda.

Don't forget torque links and roll resistors. COBB call it a rmm fwiw.
