Hi. Do you think there is a way to controle these cars with an arduino while still using the existing receiver? Is there some module that can be used to generate this FSK signal?

Not that I am aware of.

currently working on an rc car https://fccid.io/G6DGGH6A, if you got the IC used by the transmitter (RF2517A) in this from alliexpress and use Deepl to translate it's datasheet, it might do the job, since this chip does everything but the external clock source http://www.semi-mixic.com/uploads/20210823/eb2b44c87855d5d30d1646176473c880.pdf .

I'm still surprised I found the datasheet tbh, as its not listed in other lists from the same manufacturer, Fills in the gap in my case left by the confidentiality request to the FCC. Anyway the IC just does the Gfsk modulation for you, and has a maximum of 1Mbd from what I can tell, which if I'm not mistaken is the same period as Concept, and My car.
