ECS Adjustable coil over suspension for Audi S4, Audi B5 and VW Passat B5. Common aftermarket spring and shock/strut combos can offer serious handling performance to any vehicle however they have always had one weakness, an inability to fine tune ride height. The ECS Coil Over System allows you to retrofit your existing struts and shocks with adjustable spring purchases. Ride height is infinitely adjustable from REAR: .75" below stock to over 1" higher than stock and FRONT: 3" below stock to over 2" higher than stock. (stock height refers to the ride height of the lowering spring used, i.e. an HR race spring which provides 2" of lowering can be adjusted to provide up to 2.75" and as little as 1"). *coil-over sleeves work with aftermarket shocks/struts only.
