Those are Ninco Pro Race wheels so they fit a standard axle, so I used the Arrow Slot axle.
However I did need to paint the wheels as Ninco no longer makes them in Gunmetal Gray, or so I was told.
All the parts on this car are lexan, except for mirrors, and wing, so it's real light.
It was a pain to trim and fit all those parts.
Indeed, how does it run? I've got one on order and I'm anxious to hear some reports about it.
I'm currently working on a car for the Pony Wars which will use urethane tires, and cars for the upcoming 2013 CanAm which will run rubber, or urethanes so I'm trying to rubber in at least one lane of my track, which I have been running sillys on.
I installed sillys on the Ninco Pro wheels for the Arrow Slot so it will be a while before I get to tuning it.
I heard it was suppose to be competition for the NSR Mosler. I did run a dozen laps and feel it will take quite a bit of tuning to get it any where near an out of the box NSR.
However before I ran it I had removed the stock wheels and tires.
So it's hard for me to tell at this point.
