I want to upgrade to the ad22vd brake setup, What year nx should i get it from and should it be abs or no abs. Ans also what other parts are needed besides calipers............... Thanx very much..........:)

Just order it by part# :
Caliper(pass. side) : 41001-54C03RE
Caliper(driv. side) : 41011-54C03RE
AD22VF rotor : 40206-54C01
Brake hardware kit: 41080-54C26
OEM pads: 41060-54C88

These are all Part# for Nissan OEM

Here are some more part numbers for the NX brake calipers that I got from the SE-R mailing list archives:

NAPA Rayloc

342-60266

Wagner
L126784
L126785

Pepboys

40-57442X

Carquest/Western Auto

Raybestos

RC10156

These are numbers for loaded calipers (left and right side) and come with the torque member bracket and new brake pads. For rotors, you could either get them from Courtesy Nissan (www.courtesyparts.com), www.nissanparts.cc, or Mossy Nissan in Oceanside, CA (www.mossyperformance.com). OEM Nissan NX rotors are about $55 each.

cheap NX rotros can be had for $28 from www.brakeco.com. Made in China. Yes they're just fine.

Thanx for the help everyone.... Really appreciate it....
