Thanks both of you for the huge help. (especially the save state tip, it's really useful)
Using your advices, I managed to find the adress that controls the Z-axis distance between drivers at the start (adress 8088B5D0 NTSC-U )
The combined code is therefore
NTSC-U:
Time Trails Start Position in VS
0488B608 46200000 //controls the X distance between racers at the start
0488B5D0 00000000 //controls the Z distance between racers at the start
However for some reason no matter the value I input in this new address I cannot make the Z distance 0, I can only shorten it. This is already major progress though so thanks a lot.
