Cast vs aluminum drums

[tled]

I just installed a set of vector 8.5 wide wheels and 255/60 tires on my turbo T. I have an issue with slight contact on the drivers side with the fender lip. If I go with cast drums vs aluminum that are on the car will this help? How much difference in thickness are between the two?

I have read on this site that the aluminum drums are around 3/16" thicker than steel drums. Is this true?

I thought it was right around an eighth

That sounds more realistic.... Thanks

Cast drums are .127 and the aluminum drums are .247 just in case someone wants to know. That's roughly 1/8" difference. That 1/8" did help in my case.
