Caltracs work, I have assassin bars but on my car they havent been tested yet.
slapper bars on 2 cars I had, I would say they were for looks lol not for function.
Charger and dart did better without slappy
Imo, ALL depends on the quality of the current springs on the car. T-bars would have helped my 40 year old slant six springs, my ss springs?.... not so much. (But ANYthing is better than a pinion snubber, worthless weight!).
