Oftentimes, achieving a lower, more aggressive stance on today's performance cars requires dumbing-down the factory suspension; accommodating the advanced functionality of modern suspension designs is out of the reach of most manufacturers.

The KW H.A.S. height-adjustable, progressive rate springs for the E9X M3 allow for .5" to 1.2" of lowering at the front and .2" to .5" of lowering at the rear, while retaining the advanced Electronic Damper Control (EDC) system functionality so critical to balancing comfort and aggressiveness according to driving conditions.
