Starbuck Posted March 24, 2011 Share Posted March 24, 2011 Got myself a set of these dials. The ones that have keep the MPH to match the KM/H dials, so you don't need a speed convertor.I have installed them and i have used my GPS to see how accurate it is. Now i know GPS's aren;t exactly to the nose accurate (depending on your model i guess) but i have noticed that the GPS compared to dial can be out as much as 6/7mph towards the end of the scale. At lower speeds its pretty much spot on but after 35 ish its starts to go out.Could it be i just need to install the indiglos a little better and to expect some difference due to the nature of the dials and GPS?Thanks Quote Link to post Share on other sites

GTnomez Posted March 24, 2011 Share Posted March 24, 2011 The actual OEM speed dial cluster is not very accurate itself. Quote Link to post Share on other sites
Starbuck Posted March 24, 2011 Author Share Posted March 24, 2011 that can be due to your wheels/tyres.was your normal speedo out that much? it could of been?what wheels/tyres are on your starlet?It was pretty much ok before hand. 14" TOMs new actions 185/60/14I think its probably the indiglo dial slighty off and just needs pivoting up a tage on the right. I shall try it again and if its within 2mph i'll be happy with that i think. Quote Link to post Share on other sites
Raz Posted March 24, 2011 Share Posted March 24, 2011 In my JDM diesel starlet i can adjust the speedo needle my self. Match it to your GPS. Easy. Quote Link to post Share on other sites
Foggy Posted March 24, 2011 Share Posted March 24, 2011 The factory speedo is usually set to about 10% less than the speed you are doing. Quote Link to post Share on other sites
