Why does this thing cost $130?
$100 for the carbon?

yes carbon looks nice but its useless.
Make it out of plastic or aluminium. and maybe put some carbon foil over it.

And this is handcrafted? A CNC milling machine drills this plate in half a minute.

And a bar of leds and a 7-segment display only costs a few dollars.

Quote from CXC_Simulations :

Besides, when comparing it to other products like a £855 ($1700) force feedback wheels and £450 ($900) pedal sets, I thought £60 ($119.99) was pretty reasonable I suppose it's relative really. Rest assured though, the margins on this product are extremely low.

If this product worked on a £450 wheel then yes, a £60 addon would be appropriate. But it doesn't. It works on a £140 wheel.

Another Question - Why does it mount on the wheel? If it mounted AROUND the G25 (sort of like a ghetto dashboard) it would be more realistic for a "proper" car, could be heavier and cheaper etc...

Jack, there are 2 versions now, the one that mounts ON your G25, and one that sorta sits somewhere near/around your G25/other wheel.
