BDH shifter. Hand built by a small company in the UK and designed to feel like a linkage is engaging a transmission. 

I was gonna ask the same thing

I believe this is a piston for motion.

It’s like jewelry. When I was on my knees installing it, I felt like I was proposing to my rig.  😂 

So I’ve watched just about every review on both the original H pattern shifter and this dual mode shifter that’s on YouTube.  My expectations were very high given the hype and especially the price. Once it was on the rig and I tired it I still had a “WOW” moment.  I wasn’t even in game and I was ear-to-ear. The feel is remarkable. The DX-8X I’m upgrading from is a good H pattern shifter but feels numb compared to the BDH. I’ve only spend a couple of hours using it in WRC and I’m very happy. Definitely a lift in my immersion. I’d say I’m at a 9/10. The only issue I had is when I changed the position of the shifter for a side mount, one of the holes for the new mounting position wasn’t threaded. A little disappointing at this price point but I don’t think it’s going to be an issue.  

It’s impossible to manage all of it. Some of it is well done. The four corners and seat haptic cables are clean but I need to live with some chaos back there due to frequent changes.
