It is quite possible. The factory control arms aren't very durable and they do very little to keep the tires planted to the ground during wot and launches. If you are asking if these upgraded control arms are causing te noise them yes it's probably them. Whenever you add a part with performance in mind you are gonna lose comfortability and quietness so yes it probably are these that are causing the noise. I had the SR performance swaybars, end links, control arms (upper and lower) panhard bar, lowering springs, and Koni shocks and struts. My car squeaked whenever I drove over a pebble, that being said my 60ft time was almost 1.9 seconds before I added all of the suspension mods. It was a 1.59 by the time I was done giving me a 12.6 1/4 mile time with some engine work as well.
