- roll cage does stiffen the chassis significantly = much better handling.
- race seat = lighter weight. 50-100lbs easily.
etc...

there is no way the new street viper gonna get close to this time.

factory-designed roll cage :
makes you safer, not any faster

fuel cell :
makes you safer, not any faster

race seat :
makes you more comfortable when the car jukes around, not any faster
(unless you happen to lose your composure in the race seats that the ACR already has)

a few carbon pieces to save weight : (@3300 lbs)
makes you faster, but the "srt-10 carbon" edition is even lighter than the ACR-X anyways... (@3200 lbs, -100 lbs)
so the options are out already there to lighten the base ACR even more than the ACR-X

front canards :
makes you faster, the 4 little pieces on the bumper could be made stock with the 2013 ACR.
Or simply a new 2013 splitter/bumper design could out-perform the ACR-X canards.


Basically :

If,
The 2013 ACR has more power than the "ACR-X's power with modified exhaust"

Then,
The only thing holding back the upcoming 2013 ACR from being faster than the ACR-X is a few street legal changes.
The only non-trivial change being the uprated suspension.
