Coil overs mean "coils over shocks". So any coils and/or shocks that came with your BDS lift will be removed. You can probably keep some of the accessory stuff that may have come with your previous lift like extended brake lines, track bar brackets, sway bar end links, etc. But some of those things may be too long since EVO coil overs are not really meant to lift that much. More like 3-5 inches.
