The quality is excellent. I didn't find any defects in the welds or the stitching. It was easy to assemble and doesn't feel flimsy at all.I was pleasantly surprised at the weight the frame, I knew being steel it would be heavy. But this feels like industry level steel that isn't gonna bend or flex at all which is nice...
My only issue is although the extra 8mm bolts allowed me to hard mount my G920 wheel, my Fanatec CSL Elite Pedals only have through holes, and the Fanatec nuts and bolts are slightly too big to fit through the holes and slits in the pedal plate.
So if you have CSL Elite pedals, (or any Fanatec pedals) make sure you have some M8 (8mm) nuts laying around.
Additionally non of the holes and slots on the pedal plate allow for more than secure points, I'm sure with the sturdiness of both the CSL Elite pedals and the Playseat frame 2 bolts will be enough. But it'd be nice to get 3 or 4 bolts in, for ease of mind.
