Is Gps speed reliable

[tweakskater510]

Hello,
im using a gps to calculate speed
it says im hitting 33mph but when i ride next to my freinds car it says 36mph
so wuts more reliable

probably the gps... does your friend have aftermarket wheels or tires?

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.

haha no
he is running that thin big rim ganster S***

 

[cabinfever1977]

well tell him hes trying to make up for something that hes lacking.

haha no
he is running that thin big rim ganster S***

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***.

yeah but idk he aint no gangster he is almost 40
i dont like the rims i admit....my dodge ram 2001 still has stock wheels and rims
and i had it for almost 8 years suprisingly not much wear on the tires
ima check it with my truck tomarrow cause its kinda late over here
