Have you put new tyres on your cars?
After 20 years the old ones will be past it.
Classic track does offer much better grip that the new Sport Track, but that shouldn`t stop you enjoying your old cars on modern track.
Cheers.
Try RSSlotracing for replacement tyres.

Embers right.
There`s nothing wrong with Sport Track. It is designed for the modern slot car with magnets. SCX are dropping the old Classic track & have also brought out a smooth surface track.
But if you want the best track for performance, forget your Nincos ect.
Look (very hard) for VIPTrack or go on Ebay Germany & get some Fleischmann track.
Cheers,
