I have a 01 sport with right at 6" of lift recently added. At the same time I installed a SYE hack and tap and 4 degree shims which put me right at 2 degrees down on the rear pinion. According to all the write-ups this is where I need to be. My vibes are happening at speeds above 40 only when maintaining frwy speeds and completly go away when I take my foot off the gas. I thought my pinion was increasing under load so I installed a MORE Traction bar that seemed to completely eliminate all axle wrap. My vibes got slightly better but are still there. Do I need to drop my pinion more? I ordered some 2 degree shims and there seems to be a huge difference between the 2 and 4s. I'm worried that this will be too much ! Any ideas ?? Please-thanks !!!!

i know how you feel I'm still working my vibes out of mine but I would go with a 5 or 6 degree shim my buddy has 5.5 inch lift and he has a 6 degree shims
