On my 92 vert, it's an AOD with stock 2.73's in the rear. Car has Full Eibach suspension except for rear sway bar, if that makes any difference. If I have the tranny in Drive, I can't spin the tires from a stand still, unless i'm in gravel or the road is wet. But in reverse, if I stomp on it, then it roasts rubber. Is the engine lacking power, or is this normal? Or, did the Eibach kit actually improve forward traction? Traction is good .... but sometimes I just wanna smokem.... don't we all... lol it's a Mustang..
