I would like to know what the benefits are to putting a shift kit into a gn.I have a basically stock 87 with 50000miles.The car is only street driven but like everyone I like to put my foot into it.Is it mostly a durability thing or is it going to make the car faster.I have heard people say they havent ever put serious power to the ground before adding one of these kits.The one I was thinking of purchasing was Bruces.Thanks for the time everyone.
