What did you do to your Fiesta ST today ?

I just did this on mine over the winter break and I can absolutely attest to the fact that it's life-changing. What a difference ! Thanks @KXNGABE85

I'll have more details on my build thread soon, but the gist of it is :

80mil butyl insulation as a first layer : LINK
View attachment 65080

394mil closed cell foam insulation as a second layer : LINK
View attachment 65079

Wow! The 3.5k-4.5k RPM resonance on downshifts is attenuated to a large degree and the cabin is much quieter.

how much weight do you think you picked up?

The butyl panels were the most heavy parts of this. The thicker foam is quite light. I think I used five butyl panels overall. I'll weigh the panels next weekend and reply here.

Honestly, I think I added less than 10lbs.

Long day and semi-long evening. When I got back from my son's bday party around 6 there was an EIBACH, Amazon, and Rock Auto package in the package bin. So installed the following after running into town to grab a spring compressor from Oriley's.

New wipers all around
Cobra Radar Detector installed and hard wired in.
H&R Springs removed and Eibach springs put in place.

Tomorrow, Discount Tire should have my new tires (KUMHO PS31s to replace Lockouts with RT660s), TPMS sensors and Dekagram wheels in for install. Then I have to swing by a few alignment places and see if they can squeeze me in. Tuesday it's back to regular work.
