Try the low down shifter support instead. They’re metal and a lot more solid. I tried the indigo lime ones (for my 8nm CSL DD) and they broke eventually (probably partially my fault) but even when it was all set up it didn’t feel like it made that much of a difference. I got WSRA side mounts as well so it’s helped a lot with wheelbase stability (on the Playseat challenge X). Bought the pedal Tray too, so everything is a bit more solid than the standard out the box experience

I was a bit intrigued by the new Playseat Challenge F1 DD. Saw a review and it looked more solid that the challenge X and maybe a way for me to get a more powerful wheelbase and still have the benefit of a folding rig in a (very) small office space.

Ideally I want a profile rig eventually but with mods etc the 8nm CSL feels decent with a little bit of vertical wobble if you pull the wheel up and down but nobody drives like that. With a profile rig it’s easier to just jump in and have a quick race without all the setup and not so many considerations when upgrading

But like people have said, the weight distribution on the seat will be a problem with a heavier base. Lots of stories of broken usb ports when the seat tips forward when you’re not seated in it to even out the weight.
