Ok, I install the 19 mm AWR 2 way adjustment into my P5 and use the stiffest setting. I re-used the stock rear endlink and it doesn't work since it will not clear the trailing link. Then, I use the AWR adjustable endlink. Everything works perfectly except the endlinks "clunk". So, I need some help how to make the clunking noise disappeared from the endlink. I have no idea to make that noise goes away. Any idea guys? I try to put some grease but it won't help. And is it possible to use the stock front endlink since the stock front endlink is longer than the stock rear endlink? I just need a little longer from the stock rear endlink to clear the trailing link. Thanks ahead everyone
