noisy after control arm install

I installed my Spohn lower control arms last night and really like them a lot. Install took less than an hour for both. The problem is that the car makes these horrible squeaky noises. I noticed it the most pulling into my driveway when the rear of the car moves up and down a lot. Did I do something wrong, can i fix it, or do the control arms just make noise like that? They have the poly ends, btw, if that makes a difference. Also, it seems that there is a lot more tire noise. or a sound that is similar to that. any ideas on that one? did I not get the rear tires on quite right? thanks!

You're going to get a little more road noise with poly/poly. My BMR's came with a lube fitting to keep the poly side from squeaking. I went with the BMR's because they had a rubber/poly design that does not increase road noise. Hope this helps.

Hey Red how long is the life span of the rubber part? Also did you notice a difference with traction. I'm still debateing whether or not to go with the BMR poly/poly or poly/rubber. I called them and the lady told me to go with poly/rubber if its mostly a street car that will see the track about 2 times a month. But if the poly/poly will give better results on the launch then i rather have those.

I noticed a huge increase in traction with the LCA's. There is absolutely no road noise. I went with the chromoly steel, and they are several pounds lighter than the stock stamped piece. As far as the life, I know that they use a higher durometer rated material to ensure minimal deflection, so I would assume it's more durable.
