Speedo gear and rear gear

What the hell fun is that?
As if anyone knows who I am or where I am, I don't think you really follow what I am doing but thanks for the response.

Thanks Nigel, I got off my butt and did the math shortly after I posted that response.
The 43 tooth showed up today.

No problem... Check your math... 43-teeth? Either you are running wheels off a Mini Cooper S, or your diff ratio is like >4.00:1, I'm not trying to be a smart arse, but I dont think that's correct...

Thanks for the sanity check Nigel.
It's correct if you want the speedo to read 50 MPH when the car is doing 65 MPH.

this is all good but your speedometer can be out quite a bit too.
And that percentage changes with speed.Being out 4 mph at 50 may be 5 at 60.
Use your gps for your different cruise speeds to check.
