Rim backset on 68 Ghia

[rwbs04]

I recently updated the brakes on my 68 Ghia from 4-lug drums to 5-lug disc since I rebuilt and regraded the engine size. Also lowered the car 2" in the rear & 2.5" in the front.

Now my rear wheel rubs the wheel well toward the rear top corner. I even got a 5 x 205 rim with 5" backset but it still rubs. I'll running 165's in the rear. IRS suspension

I then thought maybe I lowered the car too low in the rear so brought it back up the 2" and sure enough, it still rubs.

Are there thinner or more compact 205mm disc I can get? I don't want to run any smaller tire in the rear but running out of ideas.

Any suggestions would greatly be appreciated

The wide 5 disc brake kits that are available have a range of offset options. Did you buy a zero offset disc brake kit?
