Received the Eibachs, 5100's and diff drop a couple of weeks ago and finnaly got around to installing them! The front suspension feels great!
Only issue i ran into was the diff drop came with standard bolts instead of metric, so i couldnt use the OEM Flange nut. Also they didnt come with grade 8 nuts so i had to buy some.
Other than that, I am more than happy with them! Only thing i would suggest is a good spring compressor for the Eibach's.
(by the way, i sold a guy on the setup while i was on a trail. You should be hearing from him soon)
