The springs have different numbers but probably are similar. The sway bars should be the same. The main difference is in the shocks. The adjustable and adaptive shocks on the SRT just give it a much smoother ride than the fixed shocks on Daytona. Crank the SRT to Sport or Track Mode and the shocks stiffen up and it's the best of both worlds. Where the roads are rough, I really like the default SRT street mode.
The adaptive dampening shocks in the rear are around $500 each. I noticed the price when I was looking to replace my suspension. I imagine they last a long time though.
You put 295s just in the rear BacaDon or all around? Mine came with the summer Pirellis which I imagine won't last a very long time and was wondering when the time comes whether I will stick with 275s all around or get something a little beefier in the rear.
