A calculated drop paired with spring rates matched to the factory dampers — sharper turn-in and less body roll, without giving up a livable daily ride or requiring a coilover upgrade.
iE performance lowering springs for the Audi B10 S5 give you the stance and the handling you've been looking for. A simple install gives you a clean drop, firmer roll control and sharper turn-in, all engineered to work with your factory dampers.
These springs do both jobs: a clean drop and a genuine handling upgrade. Lower, firmer and sharper, engineered as part of the iE B10 chassis package.
Spring rate and progression are matched to the factory dampers and the car's balance — enough to reduce body roll and sharpen turn-in, tuned to keep the ride livable every day.
Bargain springs are wound to a rough universal spec giving you the wrong drop, crashy ride, and feels uneven in the corners. iE's are spec'd exactly for the B10 chassis so they sit right and ride right from day one.
