ok.. i need some info on what makes a speedo off from stock.. i know it has something to do when you put bigger wheels that stock.. but not all the times.. i have a civic ex that came stock w/ 185/60/14 tires.. i have put on a set of integra gsr rims that are 195/55/15 how off is my speedometer?? and what can i do to make it more off so i can try to beat a ticket in court? a cop said he paced me and gave me a general reckless ticket but if i can get my speedo calibrated i can beat it in court my lawyer said.. need to know how to make speedo off, getting the tires to do this is no problem cause i work at tire center and can get them from the junk pile, so im not worried about buying them.. what if i put some 195/70/15?? anyone have some ideas?? THANKS

Just how "off" does it need to be? Putting larger tires on the wheels will help, but not a lot which sounds like that's what you need.

thanks everyone.. i actually found a page on miata.net that has a calculator.. http://www.miata.net/garage/tirecalc.html

i think im going to look for some 205/70/15 and that will set the speedo off by about 10mph i guess..

is there anything else i can do to make it off more??? like a speedo sensor from an integra instead of my civic one??
