Im looking into getting rear control arms for a better launch but they all look the same. Any input as to which ones are better.
Ditto here. I have already bought and installed the chromoly upper and lower control arms. I could tell a very big diference initially but after about four days it settled out. Before the CA's I was running steady 2.3s now I have ran 7 out of the last ten launches in the 2.1's. I don't feel like I have changed my driving style at all as I am trying to tell the difference in each mod, and as you can tell I'm not the best driver in the 1320I plan on getting the entire UPR rear suspension setup
