GFiveFifty

I just came across these shocks that seem to the results of a collaboration between Bilstein and some Spanish company called "4x4 Proyect" (https://vikingoffroad.com/g-class-sh...inch-diameter/). I've never seen Bilsteins for a G that come with external reservoirs. They look pretty awesome, but they're also expensive as hell. Ohlins shocks at $4,000 seem like a bargain compared to the Bilstein/4x4 Proyect shocks for $6,000. Does anyone have any experience with 4x4 Proyect in general and/or these shocks in particular? I'm curious why they cost so much and if they really are even close to worth it.
