There is nothing wrong with the factory lca bushing design.
I can say for sure my hardware and ideas have been well tested – there are only a few of us that have real test data. Info below is from over 2 decades running lap on Watkins Glenn International Raceway 2x yr/2 days per event. Both cars are street driven and can go anywhere and are not caged -the Charger has a lot more chassis work [welding etc] and less hp than the other but both ran under the lap time “number" at the Glen for a hot full lap 2 min 30 sec. I still have the 70 Charger R/T. Old iron that runs under the number gets a lot of attention.Can your car run 140+ mph with no vibration...mine do
You are welcome to your opinion. Real world experience has shown since day one that most LCA bushings won't make it to 100k. 80K for A bodies. Been there, done that too many times to believe otherwise.
And since you brought up road racing, how were the T/A cars setup around the K member? The original Dan Gurney/Swede Savage AAR was stored and maintained here locally at R & R Racing for many years and I saw first hand how their suspension was set-up. And the LCA bushing as we know it was not a part of that. You may like the way that Ma Mopar designed that bushing, but Dan Gurney didn't. He made changes.
