suspension thoughts

how would i go about converting to a cobra irs, 2002 mustang v6 auto?

i know it will fit, but has anyone done this on a v6 before, also was thinking of useing 3.31 or 3.55 gear in the rear end, maybe even 3.27s not sure would need to know about this first, before i really get into,

so i guess more or less looking for what it would take to make the change over to the irs, and ruffly cost, have more plans for the pony, but wanting to sort out suspension and brakes first off, before going into making more power, any help would be great?

not fear to the v6 crowd, not fighting just saying my piece

:OT: sorry for other day, i have bi-polar, and it' was just a way-off day for me i read to much into the threads i was reading, i am sorry, i know i should have logged out before typing in the above, as i really need info of the project i want to try, i will try harder not to have out burst like the above again, but please someone anyone gives me thoughs on the topic i did start above that one, again very sorry for out burst. this is my first mustang ever, and i'm into street rally, i know the irs style suspension set-up would be helpful in that, but also need to keep a street type daily driver, the car i found is all stock, with about 108k on it, so i already know i'm looking at some work there, but also know i'm going to need some people with more knowledge of these cars. So again sorry for the other day, but have a change of heart an give me your thoughts of this kind of build up.
