I have a set of white face gauges for a 99 cobra that I want to put on a 02 gt. They are pretty much identical except for the redline mark on the tach (no big deal), but the speedo on the cobra set goes up to 160 and the stock one goes to 150. Does anyone know how much, if at all, this will throw off the accuarcy of the speedo reading?

 

As long as the 150 matches with the cobras it shouldnt matter because they are just overlays.
