ok, want to make sure i am buying the right parts here. car has a t-5 w 245/45 17's on bullet rims(785 revs/mile), 3.55 gears. do i need a yellow 7 tooth drive gear and a pink 19 tooth driven gear to make my speedo accurate?
also, after doing the math (drive teeth x 3.55 x 785/1000 =19.50)
should i get a 19 toothe or a 20 tooth driven gear? wich one will make the speedo read more than it should be?
