I just installed a Ridetech 4 & 6" kit. When I let off the accelerator @65mph I am getting a "roaring" noise and as the speed drops a couple of mph it goes away. I am thinking that I am going to have to add a 2 or 4 degree shim. Has anyone else experienced this. BTY, I have a rcsb. Thanks in advance!
