Good luck getting used to the squishy, over-padded Alcantara on the BMW wheel.
Obviously there's no comparing it to to my current Sam Maxwell Momo Mod 27d wheel, but I honestly preferred the feel of the stock Thrustmaster GT rim over the Alcantara covering on CSW's BMW wheel.
Plus, the new 458 Challenge wheel is almost the exact same diameter as my Momo Mod 27d, so I am speaking from experience when I say it's definitely NOT "too small" -- the diameter on my Mod 27d is probably the optimal size for anybody who does GT, prototypes, and open wheelers. For NASCAR folks it might seem a little small, but I don't see the BMW wheel being all that much more realistic from a NASCAR perspective.
