anyone run subframe bushing inserts? (not collars inserts)

[240on430]

i'm thinking about getting the inserts from pdm or spl's collars.

which should i get? do the collars create more road noise?

Solid - for the hardcore. more work it install, more noise, Mans car!!!
slip ons - because your bushings are shot and you worry about noises.

The slip on collars are a hell of a lot easier to install. Well not too much, just save a lot of time.

Inserts have more road noise, but fuck it, its not even that loud.

Either way, inserts, slip ons, both well worth the money.

if your bushings are worn (like mine) it will eliminate the wiggle you feel when you go over bumps. like... when you go over a bump your rear will wiggle left and right a little bit b/c of worn/bad bushings. spacers will get rid of that and tighten up the handling.
