I like both Clint and Chuck. I had ER Polybronze on my race car for 5+ years plus other ER parts. They worked fine for me. The only issues I have with the ER Polybronze bushings was I kept on losing the Zerk fittings whenever I greased them. They pulled straight out. Very frustrating when you pay that much for a product.
I hate to say it but after 5 years, I was surprised of how gritty/dirty they were inside when I removed them. They were not smooth functioning at all. It seems that the grease compounds the problem, it's letting dirt/grit get stuck in there. You could hear the "grittiness" when you rotated them. I greased them regularly and it was nasty looking inside. I wonder what a street car's looks like after seeing rain/etc. Yes, my car is a race car, but it only saw "Hours" on the track each year, not 10K-15K miles a street car can see. I just makes me wonder.

So thats why I decided to go with Rebel Racing RSR bushings front and rear. Time will tell if those will get all gritty, but I know one thing- I don't have to grease them (or loose a Zerk fitting each time). Plus Clint will replace the bushing material if I ever have problems. +1 for me.
