For LHD vehicles, the right side of the roadway is where a majority of the salt/dirt debris ends up, therefore more salt ends up on the right spring. Thoroughly power washing the undercarriage with special attention on the bottom area of the spring will reduce the corrosion.

BTW, I've also seen the left side spring fail as well and more likely on vehicles in the salt belts. I use a good dose of QMaxx Salt on critical areas prior to winter which dramatically reduces corrosion, I hate rusty fasteners

Had this on my f25 x3 when I purchased it. Drove fine. Made a loud pinging noise when going over speed bumps because of the broken spring. Decided to just get h&r lowering springs and change all 4 instead of replacing only the rears with OEM springs.
