speedometer off
 

my speedometer is off by about ten miles per hour (speedo says 45mph= really 35mph) i have stock wheels on but i dont knwo about any gears beeing changed. what would cause my speedometer to be off

thanks

things that cause incorrect speedo are

**incorrect speedo gear for the given rear gears
**diffrent OD of tire size than b4

Find out how much its off at 60mph. Thats what it is basically calibrated for.
Then pull the speedo cable out of the tranny. (piece of cake with one nut, and a c-clip...).
Then go to the dealership and see what they recommend.
