I have a 98 v6 mustang and want to lower it as far possible. ive already changed the 4 springs but it only dropped 2" inches at best. what else can i do without using air bags or hydraulics?
you have to prepare it for an aggressive drop. meaning this:
roll fender lips or cut them out (i suggest rolling to keep fender strength in tact)
i actually had a piece of my k-member notched in the center. seen all the scrapes and welded in a 4" piece of square tubing in that exact location.
completely get rid of your rear bump stop. it will cause violent rebound when hit by rear end.
invest in a quality adjustable shock that allows at minimum adj. for compression and rebound
the lesser the spring stiffnes the better at this point cause performance/handling spring rate is just going to beat you to death when ya delete a few coils.
also ya gotta delete the cats if legal in your town. they will scrape everything lol.
i drove my car slammed to the point of tucking some tire and actually was pretty comfy compared to some with simple 2" drops from a performance spring.
