Abs increases the distance to stop in a situation where you need to stop right now, I’ve almost been in a few accident caused by absThe rationale given for disabling ABS isn't persuasive to me. But to each their own.
ABS is a safety system. Disabling it will likely disable Stablility Control as well. That may seem like a good idea to you as well. You also may want to cut the seat belts out and remove the air bags as well. Cutting out the roll cage would probably save some weight.
