Now, I’m not sure if I’m getting picky here, but InsideSimRacing have shown the install procedure of the wheel in this link:
If you’re going to have a choice, why the screwdriver for installation?
If you’re serious about spending this sort of money the Fanatec option starts to look better, with the quick release wheels.
I know what I’d rather do if I was going to switch between GTR of F1 wheels for my sim racing. Is this a mistake by Thrustmaster. I mean, how much does it cost to fit a quick release?
