I would like to get a set of adjustable shocks and a set of adjustable coil overs. I have been looking at the drop zone adjustable coilovers and the arosprrd ones. Which ones are better? as far as ease of raising and lowering and overall performance as well as ride quality? Do I need a certain type of shocks to go with these coilovers? I am not tryimg to spend over 300 for either set. About 500 to 600 hundred fot both sets. If these are no good what is? Also what about strut bars, what do they do? Do you need them? What about floor bars? is suspension tech. any good?
