Have you thought about how your steering wheel is going to affect the reach to the shift paddles? Living with the loss of some button controls? Or like Rusty said have you at least looked into the seat dimensions?

We see you posted here with stuff you think you like and prices. We don't know where those ideas came from to give constructive feedback. Looks like you just made a some Christmas toy wishlist. Nonetheless you might get a Christmas tree on your dashboard.
