djmr2,

I have the NSX-R, and while it doesn't have the racing wheels,
it does steer a little better than the standard DigiQs. There have
been changes to the chassis and the front wheels as compared
to the standard DigiQ chassis, so I'm guessing this is why it
steers a little better. With a standard DigiQ you sometimes
do accidental donuts or spinouts when trying to take sharp turns.
So far I haven't had that problem with the NSX-R.

Whatever you choose, make sure you get the Propo Special
controller!
