Project Ford Fiesta ST – Improving the Handling With ST Suspension


The rear suspension is looking good.  The twist beam has no adjustment for alignment so we are all done.
When getting ready to do the front suspension we noticed this unusual box bolted to the front strut.  We were curious about what it was.
When examining it we saw that it was really heavy and had a moveable weight inside.  It was a large mass damper placed to reduce NVH.
Since we are not super anal about NVH and more interested in getting rid of a couple of pounds of unsprung weight we tossed it in the trash.
As you can see here the Suspension Techniques front strut is much shorter than the stock Ford part.  Again this is done to preserve bump travel in a lowered car.
A problem with the Fiesta ST front strut towers is that the strut tops will not allow access to the camber plate adjuster bolts.  If you want to make the adjuster easily accessible you are going to have to cut the strut tower out.  We used a hole saw to do this.  If you don't do this, the strut will have to be unbolted from the car every time you want to adjust camber. 


  1. What class is this being built to “race” in? Asking because I noticed you did not go as large of a brake kit as I would have thought (or that we went to) to truly upgrade the system. And I don’t see any brake venting. Are you not having heating issues with your brakes? We put the Wilwood kit on my son’s ’16 and are now working on ducting for it. After melting the stock caliper seals and dust boots twice, he decided to go with a larger rotor and caliper that gives him much more pad area. I must say I love the new brakes. Let just hope they last better then the factory ones did with Hawk pads.

  2. I am really glad I found all your articles on Fiesta ST race build as I am building an ST for rallycross here in the UK. Lots of great tips and things I hadn’t considered before. Thank you.
