There were numerous revisions to the suspension for the '11 - '14 models over the '08 - '10.
The PCMs were 'cracked' by '12, so its not issue with tuning. ['15+ require unlocked PCM to tune]
The other point is the 6.4 is not peaky like the 6.1s are and there's torque all the way around.
From '12+ the multi-model Bilsteins came along. The '11s use standard Bilsteins like the Scat Packs have at the present.
There more tweaks to the Tremec six speeds to improve synchronizers performance for better shift feel as well.
Keep a lookout for an '11 SRT8 - with those being 7 models years out, the prices should be coming down. Be patient in the search for the best example.
