Default poly bushings?

I ordered the complete energy suspensions set from summit. Also ordered the front and rear sway bar set. Is there anything else I should be replacing when installing these? Also any pointers would be appreciated.

I've installed the bushings at the rear of my car while I've got the differential out to swap gears. The two large bushings that hold the 'bat wings' really SUCK. After they laughed at my Arbor press, they laughed at me trying to burn them out (nasty smoke), they laughed at me trying to drill them out with the drill press.

I ended up cutting pie shaped sections of the bushings out with a jigsaw. I THEN used a screw driver as a chisel to get the aluminum sleeve out. IF you're careful, you can do so without marring the aluminum of the carrier.

I have one of these kits, also the swaybar bushings. So far I've replaced:

rear camber rod bushings
rear bat wing bushings
ft & rear swaybar bushings
ft & rear swaybar endlinks

I didn't do the trailing links/dogbones, lots of folks convinced me that I needed stiffer springs or there would be compliance issues with the longer suspension travel associated with my softer 96 springs. Also the ride is said to be noticiably harsher with the poly endlinks. I have no idea if any of this is true or not.

I did decide to go slowly and change out each set of bushings one by one until I was satisfied with the improved handling (since none of my bushing were worn out). Right now I'm real happy with the improved handling I got by going poly on some of the rear bushings and all of the swaybar bushings.

Another upgrade I think helped my Vette out is the 30mm/26mm swaybars.

In retrospect, I wouldn't have changed the bushing on my camber rods, I'd just purchase a set of replacement camber rods from VB, they come with poly bushing installed.
