i fall for the same trap & do convert lots to AWD, especially for dirt races. Most are very good even with original engines… but lots are road/street cars & i like to keep cars original if possible.
Some RWD in B or A class can be excellent, even the odd S1 can be if i remember right…
It might help split up some ‘meta’ builds that are often in online races & possibly create more equal races for some people
