i have a 1 1/4 track with 1.38 i bleieve studs? and i want to toss it on my vmax especially after my gearing and clutch because the stock one just isnt cuttin it anymore. do i have to go with the smaller drivers if so i would have to get bigger rear bogies for my zr suspension to tighten it. also does the smaller drive increase top speed if so would me dropping two teeth on top like i did be like running stock gearing? on my tunnel when my suspension isnt compressed i have about 2 -2 1/4 inbetween track and tunnel protectors with stock track with .78 studs
