Mercedes CLA Coupé C117 2WD 180CDi Automatic/250/200CDi/220CDi (Sport suspension/AMG Sport suspension) 2013-2019 20/25mm lowering springs. The AutoStyle lowering kit provides better handling, a sporty look and is the most extensive quality program in Europe.
AutoStyle lowering springs have a progressive spring rate (the flexibility of a spring). A linear spring always compresses a certain distance at a certain weight, a progressive spring does not. The spring becomes stiffer when the pressure is increased. So you achieve better handling and comfort. The lowering springs are phosphated and have a special epoxy coating to protect against corrosion.
