I have used OEM, Energy and now Whiteline bushings in my LCAs they all seem to have their pros and cons and I drive hard, very hard, autox, track, etc.
The OEM bushings are pretty durable but are probably best for low maintenance on a daily driver and NVH is the best. The pros are they are cheap, easy to replace if you have a press and last a long time as long as they are torqued correctly. Cons are loss of precision/feel compared to the more firm options. On a DD they are probably the best bet for comfortable ride. New ones will probably work wonders if just replacing neglected ones.
The Energy bushings are ok, they are hard and cheap with increased NVH which is not necessarily good or bad. But, I had a problem with the right rear popping out of the LCA and eventually a catastrophic failure of the right front one at the track, I had to limp home, it basically shredded and fell out leaving me with a very crappy drive home. So pros are firm and inexpensive, easy to install if you have a press. Cons are they are not bonded like OEM, can be prone to failure and require constant inspection and lube. Maybe ok for a DD with some spirited driving. I don't think they are designed well enough for repeated hard driving.
Whiteline feel softer than Energy and they are pricey, but firmer than OEM for sure. The rear is partially bonded (only to the outer ring, an important distinction) so less likely to need constant maintenance for that one BUT the front bushings are very similar to the Energy ones with the exception that the inner surfaces seem engineered to retain grease a little better. For the price, I feel like they aren't that much of an improvement over the Energy ones, I already cracked the left rear one and the center hole seems to be expanding as they wear, I have had them less than a year. The right front is already damaged too, because of how the LCAs are designed the poly bushings will be cut by the LCA by routine use. Like the Energy bushings, these require constant inspection and the front ones need lube.
For me, I am going to get a set of the Mevotech aluminum units from Rock Auto and see how they do. Maybe best bang for the buck for me is to put OEM bushings back on the OEM steel LCAs in front but also maybe try the Prothane ones in the back, might be a good combo for me for spares I can swap at the track. Or maybe even get a new pair of whitelines for the rear, maybe my cracked one was a fluke.
What I'd like to know is why the price difference between 20204AG011 and 20204AG01B. All my spare bearings are marked AG011, even the ones I bought as AG01B, makes me wonder what I am missing or why people are paying a premium for basically the same $12 bearings.
