Polished and colored 96 wheels are cast Al. Polished 97 wheels are forged, painted 97 wheels are cast. P/N for 96 and 97 polished wheels are the same but the wheels are different must specify the year as well. That is what I was told when I ordered a spare set in 98. They are easy to tell apart, the cast wheels are welded between the drum and the spoke section. You want the forged wheel.
