Are you realy sure they are going that fast? or mabey thats why they won't tell you the setup because they aren't realy going that fast. I have a great z-06 and I'll see if I can get that low of a time tonight, doubt those big heavy dodges could do somthing that a z-06 can't.
Ok so I tried to even get down to a min flat but Those guys your talking about must be useing a game shark, My best run 1'06.999 in a 740 hp Z-06. I had r2 tires but even with soft or super soft your not going to get to a 56.000. I could help you with a good setup if ya PM me.
