Most of the coil over shock companys have a ride hieght(maybe the incorrect word) they want thier shocks set up to, call yours and ask them what static ride hieght they recommend on those shocks The first coil overe car i worked on had three inch travel AVO They wanted the static ride hieght set at 2 inch compressed on the springs Strange Engr. has their staic ride hieghts set similar for each length shock, so many inches between the centers
