These are American made products created for the American racer. With 3 types of scales your sure to find one that fits your needs. The Pro Scale, pretty lofty statement, and not one we make lightly. When we sat down to build a scale console that we'd want to use, we threw convention out and started on a clean sheet of paper. This is the best scale that Quantum Race Products offers. Six oversized displays with multiple functions, durable cables, and easy to carry with its own case.

The One, for budget minded racers can have the same quality scales the pros use. With the Quantum One you can weigh, cross weigh and set percentages of your race car easily and reliably.

The Kart, the very serious world of karting, designed-in chassis flex is your only suspension. Adjusting that flex and wheel weights is the difference between sticking in a turn or getting past. Designed just for karters, the Quantum Kart is everything you could want in a scale system.
