Mmm, maybe different roms? Or rom vs dsk? If so offsets may change...
Original ROM crc32 is 94FC9169, and after patch it must be 7327FB11. There are 32 (20h) bytes to swap per sprite plus the color one.
You still have to find the data that makes up the car when the car jumps from the springboard otherwise, it's weird to see the car spring back to its original shape when jumping.
How do i check crc32?
You can use HashCalc https://www.slavasoft.com/hashcalc/ if you use Windows.

By calculating it with the mentioned program, it gave me 459aff82 as a result.
It's Car Jamboree ROM file, not DSK anyway. Have i done something wrong?
Hmm... If your ROM size is 32kB, remove the last 16kB of it.
