Wilwood rear calipers offset help

[72Z/28]

Hi Guys

I have Wilwood 4 piston Forged Dynolite calipers and realized they are centered on the brake rotor. Both passenger and driver sides rear calipers are not centered. In fact, both of them are more towards the inboard side as shown in the below pictures.





I thought shims would help to center the calipers but I was wrong as you will notice from the second pic that the outboard side of the caliper is almost rubbing against the rotor.

I need your input guys on how to solve this issue.
