My wheels would have contacted the quads, even flipped. My wheels are 17X9 with 6.1" back spacing.
This topic gets beat to death, but some guys get along fine without using quads, and some guys get hellacious wheel hop without quad shocks. It all comes down to your rear suspension and wheel/tire combo, though there is no exact fool-proof method. It's a gamble.
I have Cobra Rs with 275/40/17 Nitto 555 drag radials with my quad shock on and in the stock position with no rub at all, this is why i went with Nittos instead of Mickeys, Nittos in the same size are not as wide.
and this is what it will look like
