I have a set of the older 034 version. I only used them on my car for less than 1k. The lower arms were so free to rotate compared to the OEM rubber that they would teeter back and forth upon acceleration/deceleration and making a knocking sound like a worn out pair of arms do. I'd be curious if the newer version still does the same. The ones I have are just Spherical joints installed in a set of Meyle HD arms, the new ones look like a completely new arm design.
