If you are talking about the bushings in the control arms for the rear axle, then the advise I was given was to retain the factory rubber bushings there as that helps the bind under corning loads. Basically it allows more movement in the axle. I did replace the watt link bushings with poly, but left the stock ones in the control arms and it works great.

I'm currently running PB&J mod tests on the upper bushings... I will say it definitely loosened it up even past the rubber bushings as the bushings wouldn't even stay in the housings without the inner housing... they just popped out. When I installed the lower poly bushings, they were very tight and went in slightly tough... the uppers not at all because they compressed so much easier. I am going to post about my test results later but here is what I did. The softer outer bushings I put 1/8th holes around and the middle bushings is substantially stiffer so I put in 2 sizes up from that. Here are some pictures of the work... I would say this is a good alternative to rubber bushings but will only have conclusive results after the car is finished.

Yes, because the fronts are just a couple small bushings, but the rear's include a heck of a lot more parts since it is for all 4 link corners. Lots of people buy 1 rear kit then only use half of it for the lower links and sell the other half to someone else for their lowers as well.

Nice job on the paint work Sam. What kind of paint/primer did you use? Some of those pieces you've painted, I could have powdercoated for you instead. :)

I have a very nice silver metalflake that would would really set off the engine bay and add some bling bling, lol.

well the rear end is in the car and so are some of the part, sorry i don't have pictures of it in the car but here it is all assemble and some more stuff ...
