Dave's explanation of the weight requirements for DMOD is correct with one exception. For those of us with 1800cc's or less the minimum weight is 1280 pounds, plus the 40 pounds for the modified tub, for a total weight of 1320 with driver. Tom
For those of you with those HUGE 1801-2000 cc motors, you pay a penalty of 100 pounds bringing your minimum to 1380 plus 40 for the modified tub, so 1420 is your minimum weight. :_deadhorse:
