Magnum Farce was either developing or selling a coil over setup for the 3rd gen B bodies but they seemed to have dropped off the radar. Maybe because their reputation caught up with them.
Seriously....Too many enthusiasts get caught up in the hype of these coil over setups.
It stems from their lack of knowledge and experience.
Most have likely never been in a classic Mopar with a well sorted stock based front suspension. The design isn't the problem. Bigger torsion bars/sway bars and proper shocks on a front end with good bushings and ball joints is an impressive setup. The ride can be excellent if the right shocks are used. Years ago, many defaulted to the few "performance" shocks we had to choose from including KYBs. Those are stiff and give a harsh ride when you use larger torsion bars.
I've heard it so many times.....
My car handled poorly so I bought the XYZ coil over kit .(For $6800) It performs like a new car now!
Uhhh...Well, your car had an original front end with worn bushings, ball joints, tie rods and shocks. Now everything is new (in the coil-over kit) ...and you're impressed at the difference?
If you hadn't eaten in 3 weeks, a dang baloney sandwich would taste pretty good too.
Comparing a worn out suspension to a new aftermarket design is an apples and oranges comparison.
To me, a change from the norm has to include advantages. First off, the coil-over kits can be 3X the price of a basic rebuild of the stock design.
Secondly, the change should be an engineering upgrade. In most cases, these coil-overs are not. They move weight forward and UP in the chassis. The overall weight may be less but it is moved in the wrong direction.
The changes should increase durability and safe operation. The coil-overs do neither.
The changes should be affordable, These are far more expensive.
