That design is definitely better than traditional rubber/poly bushings... but when I saw "bearings", I was thinking bearings like a real roller bearing or something.
The del-a-lum bushings or "delrin" have been around for awhile, most suspension companies offer them, PTFB has them in their lower A-arms... Im helping a friend with a pro tour type build on a 73 formula and I steered him towards the PTFB stuff with coil over front springs/shocks and the delrin bushings. I want to change to them on my 72 firebird that has OEM rubber bushing on the lower A arms & rear springs. Good to hear they ride better than factory bushings.
