Coil Over vs Torsion Bar

It seems like everyone is intent on determining or trying to make the case of one system being better or more advantageous over the other; you can definitely find benefit and fault with both systems, but let's throw some ideas out there for anyone who isn't as familiar with suspension systems as some (as a caveat, this discussion is focuses on Mopar platforms, not vehicles in general);

TORSION BAR SUSPENSION
PROs:
- Already present, no fabrication required
- Time tested, proven to work
- Decent amount of T bar sizes to be had to modify the suspension as required
- Easy to adjust

CONs:
- Takes up room under the vehicle
- poor T bar selection (or replacement) could result in very poor handling qualities
- Removal/replacement requires vehicle to be lifted

COIL OVER SUSPENSION
PROs:
- Very adjustable via springs and shock selection
- Does not obstruct anything under the car (headers/exhaust)
- Time tested, proven to work (if installed correctly)
- Replacement/adjustment/removal easy to do

CONs:
- Requires a considerable amount of fabrication or replacement of factory components
- limited space for shock travel
- Can be expensive to obtain/install
- Incorrect installation, poor component choice could result in significant issues

So as I look at this issue it stands out that from a simplicity stand point T bars are the way to go, however cars (especially hot rods) are seldom built with simplicity in mind, rather they are an expression of the owner and thus not subject to reason/common sense at times; in other words we build our cars because its what we want regardless of what other may think. It is not that coil over is better or cheaper, its that it is different and in some cases it may be necessary depending on the selected drive train (although pretty much every common engine/trans combo has been successfully installed and ran using the T bar system).

Coil over is neat because the cars didn't come that way and for some this is all the reason required to change, however T bars have proven themselves completely capable of meeting all of the demands required of it ranging from NASCAR to street car and everything in between. I've already explained why I am going to do one, but if the car was not as altered as it already is I probably would be sticking with the T bars.
