Welcome to SlotRacer shafe 
It's not uncommon to get a pair of cars with wildly different performance out of the box, even if they are identical models. It could just be the way they've been put together at the factory, one perfectly, the other not so good. Or there could be differences in the components (motor, magnets etc).
Getting them running at the same speed could be a STEM project in itself
There are loads of simple tuning tips that don't require buying more parts - you could work through these steps: https://slotracer.online/community/showt...p?tid=5204
The Carrera cars have two traction magnets, one usually below the rear axle and one in front of the motor. Removing the rear magnet will free up the cars and their performances could be more equal. You can also shim the magnets to raise them higher off the rails and reduce the downforce.
Electronically, a solution might be to introduce a resistor into the circuit - either to the lane or inside the car - of the faster car.
Do let us know more - what set you got, the specific cars and exactly how they handle on the track.
