Are 1 43 scale slot cars compatible with 1 40 scale slot car tracks?

Answer 1

The short answer is maybe...some will and some won't. The only company that made 1/40 scale cars and track was Carrera; Profi, Car Racing, and Servo140 slotless. The biggest issue will be with the guide pins of one manufacturer being too wid to fit in the trakc of another manufacturer. I think the Artin guide pins are too wide for Carrera, but the Carrera cars should work fine on Artin tracks. But since the Carrera cars are slightly larger they may not fit side by side on Artin track.

My advice is to stick with the scale you currently have, you'll save money time, and headaches buy going with what you have. Artin is easy enough to find here i the US. But if you're stuck with the Carrera 1/40 stuff you will have to shop eBay Germany to get the parts you need. Prices are cheap, but shipping can be astronomical. Be sure to get a shipping quote before you bid; sometimes the people will inflate the shipping costs to cover the inconvenience they feel for shipping internationally.
