Coil Over vs Torsion Bar
Well, I understood from my mechanic days (1977-1981) that rack and pinion coil over suspension is ideal for cornering whereas torsion bar suspension is better for ride stability and comfort.
I had a 1992 Camry V6 with excellent cornering characteristics. I placed a tall cup of ice on the front passenger floor and went around corners in city driving. I also went on the freeway and made cloverleaf transitions at speed. The cup stayed put. Similar results were obtained with my 2007 Charger. I have taken two day road trips with both vehicles and I always seemed to be road weary at the end of the day.
I take my 1969 Polara 500 C-body whale out for a daylong drive (I also take plenty of cash for the thirsty HP 383) and the car just floats down the road without transferring the road vibration that comes with the other suspensions. Small bumps and dips don’t register at all outside the “thump” that I hear the tires make. I don’t get road weary in that car. Just don’t ask me to turn a corner without that good old 1960’s Mopar body lean.
Each system has its advantages and disadvantages.
