Trailing arm question

[grocerygetter]

From a nvh standpoint, being that my car is an auto, I thought about trying the stock outer bushing instead of changing it when I do the aftermarket pfadt arm package. My question is if it would act like a control arm change on a four link solid axle car...poly bushings on that car transferred a lot into the cabin. How about our cars?

Four links have control arms? None that I've seen.

My terminology is proper. GM g-body(87 GN)..I had upper and lower metco control arms. The function is different than said control arm on our cars.

I would suggest going with the poly for the outer bushings. They don't transmit any nvh. You have huge rubber bushings isolating road noise anyway but even with solid sub-frame mounts it still isn't an issue.

Please feel free to call, email or PM me anytime with questions.
