The quick rack is a simple unbolt old one bolt in new one job, but trying to find one is not so easy the quaife unit's are few and far between I believe.
EPAS is something you'll have to sort yourself, dont know of any tuners as such that fit it, Crazycage on here has done a couple but he's up north.
Same goes for the Hydraulic clutch, not that hard mate, just take a look at my guide.
