The Mopar front suspension was designed as part of the unibody package of the Mopar. It places a lot of the stress under the firewall area, away from the front end. Whether the front end can withstand the added stresses of having all the duty of supporting the front half of the car is a question for an engineer; which I am not. But I would be one to not even think of taking that chance. The fact is that may use the coil over systems. And I know that they are not all the same. How much research was put into each of these systems is another matter to consider. What roads you drive on, how often you drive, and any number of other parameters will enter the picture, as to how long your vehicle will remain safe, structurally sound and operable is a question that would be very difficult to answer. It is not a matter of conjecture, however, that the fact is - and this is a big caveat ... w/o adding additional support to the front engine area unibody - the car's structure will become fundamentally fatigued using the coil overs. Others have commented on how wonderful these systems make the car feel. But, even if that is true, I would stay away - unless, as stated above, you add support to the front unibody. A well set up (good parts and good alignment) front T-bar suspension works very well.
