    I have a JDm spec type r gauge cluster in my civic that reads in km/h. According to my gps the cluster becomes more inaccurate the faster you go.

    stock wheels???... I hope

    I cant imagine a porsche speedo being too far off though.
  7. haha no
    he is running that thin big rim ganster S***
  8. well tell him hes trying to make up for something that hes lacking.

    that is why... he needs to have his speedo re-calibrated.

    IMO You need to tell your gangsta homie to take the s*** wheels off and put the good porsche wheels back on. I will bet the porsche wheels are more expensive and better quality than what he replaced them with.

    I never understood why people do that... a porsche isnt a gangsta mobile. It is a track car... Ill bet he cant drive it right either. its kinda like seeing a hot girl with a guy you know isn't giving it right.... what a waste. Wish it was my porsche, I would take it to buttonwillow and show it some real love.... not that gangsta baller s***.

    sorry for the rant... speedo w/stock wheels should be accurate. Has to be accurate to measure millage correctly for DMV and insurance.

    I have two GPS units, and they are within one MPH of my speedo in my cars (and one car is an ex-police Camaro with a certified speedo)
