Who has new not yet installed Sub-frame inserts in their hands?

Does anyone have Sub-frame inserts in their hands?

I need the measurement of the diameter/width of the 4 legs on each side for Rear set and Front set. And also the Height of the inserts legs until their bases

Why? Because for science. I want to see if some other material can be used instead of Poly.

If you have used OEM sub-frame bushings you can help too

EDIT:Visual inspection of images, compared to the center hole which is for a 12mm bolt. This means that the bushing holes are of a diameter of about 6mm

Can anyone confirm?

I have some that I'll measure this afternoon, you could fairly easily insert some other material into the bushings as the whiteline inserts are fairly soft.

Thank you! My goal are inserts that are a easier DIY, no subframe drop

I've wondered this as well. Since they're inserts and not the entire bushing, why not delrin or something way stiffer than poly.

Derlin, Nylon, Teflon are easy to find in rod form and they take heat & squeeze forces. The challenge will be diameter and selecting the material that wont break or shatter easily. One cant use metal because that will scratch the car underside
