I had a DD plastic quick release on the Mclaren V2 start slipping in a week. Never overtightened and not a lot of force. The G Pro quick release is eons better than anything Fanatec offers .
That Plastik QR on the VR has a different issue. In a phone call the tech support told me that all Plastik QRs would have the same issue:
It's not actually "clamping"! It's slightly holding inside the moulds for the metal QR balls but mainly the rotational slip is blocked by the plastic strips at the top.
Normally they should be a bit too wide and push against the edges of the slot but instead there's a gap and there's some rotational play.
You can do 2 things about this:
1. Fold some paper (I'm using 3 layers of 80g DIN A4 printing paper).
Put it around the strips strips/into the slot with a few cm sticking out to hold it with your hands.
Then carefully slide the wheel onto the shaft while keeping the paper in position.
When it feels better, cut off the sticking out paper.
This basically makes the strips a bit thicker/wider while also damping the rotational slip.
I can't feel it anymore.
2. You can take out the end stop for the tightening screw and simply screw it further until it's tight.
This clamps down the balls into the moulds and it seems to work.
There are videos out there but I didn't try that since it voids the warranty and I didn't see a way to get the end stop out and back in without clear signs of it, might the support take a look...
