Discounting the weight of the car, in most cases an auto trans is a must for drag (bracket) racing. It is much easier to perform consistently with an auto than a standard trans. On the other hand, if you're looking at a Lenco or Liberty or other gear grabbing box which are technically "4-speeds". that's a different story. If you want to be consistent, it's easier to get there with an auto, unless you got serious skillz with a stick.

Two cents,
