I'd start with the CAI/tune and 3.73s. Look thorough the 2011+ forum here and you will see 3 or 4 threads with dynosheets on my mods.

Don't worry about the clutch. It will handle more than you can throw at it till you throw boost at it. My stock clutch has about 50 passes on it and it is good as new. Some leaving at 6 grand on DR's. A few 1.6x 60 fts in there, too. Never slipped once.

As far as the suspension there are lots of options. I have the Roush UCA, Steeda springs, and Koni yellows and wouldn't change a thing.
