There seems to be a bug in RBR somewhere that would seem to enable RWD without swapping the front/rear wheels.
I have the e30 m3 downloaded and works correctly as a swapped front wheel drive driving the rear wheels.
However, when I change it to 4wd the car turns into a front wheel drive (yes, no rear wheel drive at all)!!!
So there must be a bug somewhere created by my modified suspension setups (that car need LOTS of suspension geometry work). If someone could pinpoint this bug then the same thing could be used on any car to make it rwd without needing to swap around the wheels and loosing the handbrake.
Everything in the setup seems reasonable to me so I have no idea what is causing the loss of drive to the front wheels (that are in the back of the car)? |

Did some testing today. It looks like the bug has something to do with the "compatibility" between the common.lsp r_*.lsp and d_*.lsp files.
With the front and rear wheels swapped:
DriveType 3 = rear wheel drive
DriveType 1 = front wheel drive
With front and rear wheels swapped back to original positions:
DriveType 3 = front wheel drive
DriveType 1 = front wheel drive
This is quite strange.
As a comparison I tried changing the setups for a stock car and that worked as it "should".
DriveType 3 = front wheel drive
DriveType 1 = 4wd |

This is very interesting. You have now a setup which stays FWD for DriveType=1 and 3.
Did you try other values of DriveType on this setup?
I still don't understand why people didn't create RWD cars in RBR. Excepted the hand brake problem, it works really nice.
For example, take the subaru 2003, switch the wheels, disable the turbo, reduce the torque, move the center of gravity 30 cms back (-1.10 instead of -1.40), loosen the front differencial (now rear) and you get a nice driveable RWD!!
It behaves exactly as it should! |

from RBR code:
if DriveType is 1 : 4WD
if DriveType is NOT 3 : 4WD
else FWD
so in other words, only if DriveType = 3 you have FWD, any other value meaning 4WD, the code for a RWD does not exist. |
