it should still work on stock springs, the only thing is your spring rate won't be at the similar level as the shocks. that goes with the type of driving you do as well. to me there wouldnt be a good equalibrium cause theres a lot of bumps and stuff, so most of the work will be going into the struts. if you dont drive hard much then there shouldnt be too much to worry about. i went with the eibach sportline with tokico d spec and 18s. i have to go slow over speed bumps and worry about scraping and i have scraped the exhaust pipe plenty of times but im willing to take the sacrifice. also my driving isnt really that mellow either so ya.
