have no idea what S4 springs are . . . 

also they mention VW Motorsport Steering Wheel - have no idea what that is either . . 

and what are military tail lights? i do recall there being a place for another bulb in the rear lens assembly . . .

Nice cargo cage . . . since I'm getting two thule spirits on top of my vanagon,  http://www.thuleracks.com/thule/product.asp?dept_id=11&sku=689B . . . I'm wondering would it be better to mount a cargo cage in front of the thule spirits or behind . . . if the thules are in front then they'd be cutting the wind first . . . but if they are in the rear then maybe their placement would be more typical ? ? ? . . . as far as loading stuff on the cage it should make no difference if I have tube bumpers front and rear for stepping on . . . and the cage would be good for having for loading things that you might buy from ikea-like-stores when you're on a day trip and you don't want to cover the engine bay area cause you might want to take look at your engine or something and admire it . . . for example I just changed my four wheels . . . now I have four tires I have to transport . . . would be nice to have a cage rack on top to be able to transport these without needing to put the wheels inside . . . though I'm not sure if I could actually put that many tires on top . . .
