A month ago I installed the H&R Spring lift kit for my Bronco Sport BB, its a small lift, just 1.2 inches (3cm), but a perfect complement to the larger (245/60R18) tires I had installed earlier. It rides the same, my wife says smother. No problems and no fuel penalty.
Got my Bronco Sport Big Bend this Monday! Very happy with how it drives and overall quality.
First two mods were to up grade tires to BFG Trail Terrain 245/60/18 and wrapped the roof in graphite/silver & hood in matte black.
