Is it possible to replace 200MPH speedometer with 300 MPH speedometer???
I need help!
I would like to replace my 200 MPH gauge with 300 MPH speedometer.
I was assuming that of course it is possible to swap but I could not find any threads for that.
Does anyone know if it works or if I have to do additional programming?

I have a 300MPH speedo and Z06 Tach conversion from him.

The 300 speedo is the Canadian spec to read in kph
Not sure of the implication of putting it in a US spec car with a US sw package. Surely by selecting metric it would misread if it still thought the speedo was calibrated in mph?
Maybe someone can explain.
Just wondered why you need one. Planning to break the 200 barrier?

I have seen a few of the conversions, and they are cool. I wonder how much the loss of gradient when using MPH is a bother? In typical driving, do you have to look closely to tell if you're doing 55 or 65?

C'mon it is just cool and fun. I don't even have relatives in Canada so I'm clean
I found a company here in PA who possibly does calibration. Could this be something???

IIRC, no C5s need to be recal for gear changes, but the A4s need to adjust shift points. Speedo uses wheel speed like the TC system.

Where's the cool or fun part? Seems like putting your money is other places would actually add more fun when you put your foot in it-who looks at the speedo besides you?

You'll need the Canadian cluster, along with an odometer program to the canadian cluster. I may be able to help you out with the latter for a minimal fee, or I can point you in the right direction.
Other than that, they're a direct swap. I don't recommend it without a HUD projector, as it's really pretty difficult to read accurately at normal speeds. The left 2 gauges are Canadian specific and can be replaced from the back by way of 2 phillips screws each.
I will note that I have seen some canadian clusters which always default to kmph on EVERY startup, though that's not the design of the system. It should start in kmph at first, but if you change your preference, it should maintain it unless your car loses power.
best of luck!
