Has anybody tried these polyurethane bushings? They look like Powerflex ones but at a much cheaper price.
Amazon.com: ADUS 648 - BMW E53 X5 Rear Sub Frame Bushing: Automotive

I'm pricing quotes between Febi and Meyle HD bushings too. RM European has the FEBI bushings the cheapest for $102.80 and FCPEuro has the Meyle bushings the cheapest for $167.80. Just a heads up for anybody looking to tackle this project soon.
