13 inch rotors from GMT900

[John Cunningham]

Now from what I understand moving to a 17 wheel the GMT900 rotor will work. If your switching over to a gmt800 anyway get the bigger brakes because they make that much difference from a gmt800..so jumping from a gmt400 to a gmt 900 is what you should do if you want to change your rims.

Here is the question...2003 and up dodge Rims on an 8 lug have the same bolt circle and correct width.
17x7.5 and here is what I dont know..........whats the backspacing and hub dia

Has anybody used these wheels?..........what an easy cheap way to move to a 17 steel wheel
