anyways, back on topic, there's no reason for u to race a automatic...what i suggest is to abandon that granny-shifting mode of yours and learn manual. It's not that hard, shift up when the red lights appears on the tachometer. One advantage of manual is that you get alot more control of your car and increased corner speeds. Like that XRR on auto, you get that uncontrollable wave of boost on the exit... (i dunno if u know what i mean...)
