My speedo seems way off. I put in 3.27's in my 5 speed, and i changed the gear to a 21 tooth (red) gear. The needle says 50.....but i cant even be going 40. On the highway it'll say 85 when i'm going about 70,,,if that.... What tooth gear should I have got??

I used the black (20 tooth I believe) speedo gear in my '95 with the 3.27's and stock size tires. Speedo seems accurate, but I have not had a chance to verify it. According to the sccoa speedo gear calculator, that is the gear that you should run with the 3.27's in a 5 speed car with stock size tires.

my rear tires measure 26.6". When i plugged in my info..it told me to use a 20 tooth gear. It seems like that would only make it read even faster than it already is.
