Arguments for solid vs poly?

The subframe full bushing replacement is exhausting but worth it. I did the whiteline diff bushings and Voodoo 13 solid subframe bushings at the same time. I have not noticed

The subframe full bushing replacement is exhausting but worth it. I did the whiteline diff bushings and Voodoo 13 solid subframe bushings at the same time. I have not noticed any real increase in NVH from the subframe bushings but I can imagine there will be some whining if both are solid.

Some how my Z1 diff cover has survived 1.6 second 60ft launches on 28x10 bias ply slicks. Thinking about swapping out to solid with a diff brace for next year though.

Good to know the poly mounts can handle that. Why are you considering switching to solid though?

I won’t be doing anything that severe with my car. Autox launches and future track days shouldnt torture the car like launches with slicks lol

I don't want to test my luck any further with the single stud cover, if i get the Z1 brace that's solid I may as well remove the movement the poly bushings will have. That's my train of thought anyway
