2WDrifter - GO FOR IT! if this keeps you busy tinkering and shooting for a goal, more power to ya dude! But, what you are trying to accomplish is "almost" physically impossible, especially to do it consistently and in a layout. Sure you will probably achieve some bashing around type drifts but if you ever want to drift with other guys in a layout where you need to control your placement in a lane, clipping a marker and so on, you will need a tuned 4wd chassis.
But I must say I love your drive and determination!
