I had a spool in a tubbed , 14x32 , 406 vega,drove it on the street for a couple of yrs. u could tell it, but wasn`t near as bad as people let on. drove it in the rain a couple of times back from work 28 miles each way. more problem from hydro planning the M-T`s than w/ the spool. (Don`t try this at home!) unless u have a lot of experience .
