Coilovers are smaller than the original springs and shocks.
They are ride height adjustable and some come with dampening adjustable features.
Ive got coilovers on mine, the handling and cornering is much stiffer (better) than the standard springs/shocks.
Mine doesnt have the dampening feature that allows me to adjust the ride quality.
This makes it a much harsher ride.
hope that helps
