This Playseat have pre-drilled holes for the Logitech G27 wheel, pedals and gearshift. It came with all the screws to attach it and it bolted on very solid. It’s a good design for me. I have been using this Playseat for a few months with Dirt 2 PC game and I am really enjoying it more than playing with the G27 wheel on my desk.
