Yes, you can attach the gearstick lever holder, and you can do it very well. I am very satisfied with the chair. And everything is well fixed and holds what it should. Really great 👌🏻😁
I have had this seat for a few years, combined with Thrustmaster 458 steering wheel, triple pedals and manual gearbox. Never had any problems with pedals slipping away, although the Thrustmaster triple pedal is quite heavy.
