Not many but i'll tell you this. I hid my compressors and tank under a false floor. Added a second 380c compressor and also 2 water traps, hanging off the end of each tank fitting.
You can see the tank here, this was before the second compressor was added.
And you can see the controller here:
The Install manual tells you this but i'll re-interate here.. You need to bash in the area behind the front struts or you'll have clearance issues with the front bag rubbing.
Also you'll notice I have the SPL FUCA's to correct some camber.. I'm on 20's and like less than an inch from getting the front bumper on the ground because the control arms hit the inside on the fender when fully aired out. 19" or less wheels shouldn't be an issue.
