dont really look at coilovers as an easy way to drop the car for corners.... yes there is ride height adjustment ability, but its more for finetuning then casually rausing and droping it... remember every time the height changes, so does the camber... thus the need (recommended) for an alignment every time. its more or less to dial it in to where it needs to be, then leave it alone...
coilovers reduce unsprung weight, allow for stiffer ride with softer springs (think angles and location) and faster more stable movement of the parts. I will be getting front coilovers, but think i will be leaving the rear seperate.
from MM when i E-mailed them last: subframe connectors, springs, struts/shocks, CC plates, LCAs, PHB, Torque arm (i think i will be using the evo tri link though) and then move to the front with coilovers, A arms, k member + k brace/accessories, then fine tune with swaybars.
the standard black and white answer from MM comes down to subs first, period, fix the rear, then go to the front. I did it out of order and went springs/dampers first, now going subs and swaybars (already purchased, or i'd get LCAs and PHB) then LCAs, PHB, Tri link, coilovers (front) A-arms K member and all the needs (tie rod ends, endlinks, look at MM k member package to see the rest)
i will be getting the whole gambit as i am not nearly happy with my springs and dampers... so i'll re-evaluate after my subs, swaybars, LCAs, and PHB are on and see then if i need to move to the front (100 bucks says i feel i need to) so, its horridly addicting... i've done power mods, but i got the handeling sickness over the power hunger... so, i hope i have offered some insight from MM, as well as my own.
on a side note i really like
www.stangsuspension.com for awesome prices. thats where i got my bilsteins and HR race springs. noticed a good difference in handeling, almost no sacrafice in ride comfort (thanks to the bilsteins), but i still wanted more. personally, i'd go the same route, but getting subframe connectors first, then step into LCAs, and the PHB, and sit it out for a bit to see if you want more, and where that more needs to come from. actual handeling is a math/science game, not just tossing on eibachs and calling it a day. I dont claim to know everything, but Tom does
