Fiesta ST Rally and Offroad mods

[mulliganisoup]

Just a followup - I did some poking around in my spare time, and while KYB doesn't carry shocks for the Ecosport (they have a good database that includes shock dimensions), Monroe does (and also has a list by part number you can look up), and additionally it appears shocksurplus.com has included shock lengths in their catalog for the Bilstein B6 and B8 shocks. Here's what I found. The red is a guess because the Ecosport B6 rear measurements were missing, but it seems about right based on other B6/B8 shocks

The Monroe lengths, at least for the Fiesta rear seem pretty close to the measurements I've seen previously - not sure about the front. The Ecosport Bilstein B6/B8 shocks are definitely taller. 1.5" in the front and over 2" in the rear. Shock travel is not that much different - Ecosport B6 has an extra 0.5" of travel in front which could be interesting (except for the serious lift you'd end up with). While the rear shocks are taller, the travel is similar or slightly less. The damping is anyone's guess. Its interesting that the Ecosport B8 is a "lowering" shock like the Fiesta. For trucks/SUVs and other "offroad" vehicles, the B6/B8 are flipped, and the B8 are sometimes for lift kits.

To Add on to this. I was on fords parts site and the fiesta se has two front struts.

Seems like the rear gives you an imbalance if you swapped both
