Difference between Poly bushings and rubber I am going to get BMR LCA's and other susupension components for my daily driver. Whats the difference between poly/poly bushings and poly/rubber bushings?? Also since I only see the track autocross and drag about twice a year and ride comfort is one of my top concerns, do I need chromemoly parts? Also what is chromemoly and why is it better? Any help in this would be great. Thanks.

As for the Chrome Moly, Chrome Moly is a material that has a much higher tensile and yeild strength then mild steel, it is widely used in the aircraft industry. It allows you to use thinner wall tubing allowing less weight and still keeping the strength that a thicker mild steel tube carries, or even stronger. From what you said about how you drive, the chrome moly version would just be over kill for your application.
