for stanza struts, you will need stanza control arms and such, which will end up increasing the track width a bit
in standard form stanza brakes are alot better than 120y ones, but depends if you are going to upgrade to bigger brakes

you can use landcruiser 4 piston calipers on stanza struts, then just need to find some discs to suit

main advantage of 120y struts is that they will bolt straight in and you keep the same track width, if it was me using 120y struts the brake upgrade would be the first thing on my mind

im using stanza struts, well was, now using 200b struts pretty much the same but shorter (need to change spring perch also)
and will soon be running the landcruiser 4 spots, but ive changed brakes 3 times without driving the car, i just want big brakes
hope that helps
