Disappointing.....my sig shows my mods on stock 18's and tires running a 13.18 @105.91. Today I go with the addition of an aluminum driveshaft and Bogart rear wheels with Mickey T drag radial and my best run was a 13.241 @105.92 with a 2.141 60ft followed by a 13.251 @105.18 with a 2.061 60ft. Im pissed at this car. Granted my 13.18 run was in 30 degree weather so I'm going to give this another shot in December but I was hoping 13's was going to be a thing of the past. Not like I can do anything to mess up either since its an auto with stock gears. What a disappointing trip, I was going to wash it this afternoon but I just put it away, I can't believe it's slower.
