Good Improvement! I bought this car used and when I did my first tire assessment I quickly realized that Ford made the wrong choice with the nuts! They were plated with chrome and as a result swelled from the heat and became a nightmare to take off! They arrived quickly and fit my 20" OEM factory wheels perfectly! They appear to be well made, screw on well and shouldn't bulge like normal ones! They've only had them a week so I can't comment on the structural strength and durability of the finish. I can only recommend it because of the price.
