GT DD Pro on a Playseat Challenge 

FYI, I upgraded to the trophy, playseat challenge can handle Elite v2 pedals but with limitations, even the trophy has its problems. I guess aluminum profile rig is still the end game for sim racers. Challenge was perfectly fine for me until I no longer satisfied with brake force setting at only 15…

You can try to search for Fanatec V3 pedals adapter and play seat challenge reinforcement. I’ll ask the store where I got them see if they have shop on Alibaba or other platforms that ships internationally.

I think that is what you’re searching. and it’s a totally free STL file

It depends on if you have drilled new holes on the base plate if the base plate is closer to you, you need less weight. Anyway, 2.5 kg x 2 should be enough to stabilize it.
