Will these tires fit on viper 20 x 8.5 inch rimS?

No. Minimum rim width would be 10 or 10.5 inches

I saw on the nitto website that it's good to use the g2's on the front and the r11's on the back. Is this better?

It is what I run on my 2018 ZL1 Camaro. I am on my second set of RII and still have the first set of G2 on the front.

Do they fit 2011 2ss camaro without spacers ?

I don't know since I am into MOPARS only now. I used to have several 1967-1973 but none of the newer ones.

Can you put them on a 9.5 inch rim

I believe the minimum recommended rim width is 10 inches. I have them on 10.5 inch and they fit and work well
