Hey Dave,
No doubt they are better than drums.
The drums will do the job just fine on rear. For the difference in performance VS cash it wasnt worth it to me at this time.
Front disc yes all the way.
BTW check out the roller paint job post.
Ive done a few of those all came out great.
I used one shot sign paint tho on mine.
I think the rustolem may be a better product that **** is tough as nails.

 

looks like a lot of work..but it's lookin' good!!!
