The new 5-door progressively-wound springs from Mountune and the U.S. domestic market 5-door Ford Fiesta ST will be here soon!
Today, I had the lucky occasion to experience the new springs in my own FiST! These are a subtle change over the Euro-spec 3-door Ford Fiesta ST, and a nice change in the stance over our stock units! My FiST sits about 1" lower now.
In this case, we're looking at a modestly stiffer spring-set than the stocker. Here are some #s for comparison:
Front Stock: 30 NM
Mountune: 19-30 NM, progessive
Rear Stock: 24 NM
Mountune: 10-25 NM, progressive
Frankly, the ride isn't much different than stock. You'll notice a lot less body roll, and stock wheels and tires have no rubbing issues of any kind.
My extra-wide 225s barely rub the plastic liner on extreme cornering, but actually fit without issue for normal driving.
It should be noted that despite lowering the ride height about 1", we don't gain any noticeable negative camber. I haven't had the car aligned yet, but will do so soon. This is expected to give me another 1/2" or so clearance -- and allow even my 225s to clear!
Overall, these are a nice improvement to handling and big improvement in the appearance of the car's stance.
Here are a couple photos of the car from today:
