I have the g27 and Logitech doesnt make wheels anymore, I think if I was you I would get it soon as possible before they run out, I got mine a week or 2 ago. Definaly amazing! From what I heard the the owners of gt5 said some stuff that gt6 would go on ps3 as the last gt on ps3 then gt7 on ps4, but who knows what happens I'm hoping it stays on ps3. As of rig. I built a wooden rig still use it! Very sweet but the chair I use can be uncomfortable at points, but I'm getting a evolution playseat for gt5 so its more comfortable, amazon said its estimated to get to me by Monday, which would be nice since then I can start fresh off during that week instead of like on Saturday or something like that.
Just some advice if I were you. See you on the track this weekend hopefully!
