Hi all,
Hope everybody O.K.got a question for you, i need to replace the Upper Control Arms on the old girl (e43 B10) and was thinking about going for Urathane bushings instead of rubber. Has anybody got thoughts on this. Pros & Cons much appreciated.
Cheers

Urethane is stiffer than OEM rubber. It has a hardness of about 80~95 on the duro A scale. Whereas rubber is somewhere between 20~80. Translate that to slightly better handling with less flexing with urethane.

What I do know is that urethane bushing for the anti-sway bars does require constant care and lubrication, cos it in direct contact with the moving bar. Rubber is almost maintenance free until, of course, it hardens and starts cracking.
