What is the fastest top speed you have achieved in your B58?

Not just BMW. Every single car manufacturer. There is always a deviation and it always in the same direction (indication higher than actual).

Most likely done to conservatively avoid penalties / legal suites for speeding.

The deviation on my Audi is even bigger (> 10 km/h for speed above 200 km/h)

Yes mine speedometer 100 km/h > 97 GPS, 200 > 195 GPS, 257 > 250 GPS, 290 > 281 GPS

I think with tailwind 300 Km/h on the speedometer is possible.

It's amazing a non M car can reach those kind of speeds, that was super car territory not so long time ago.

I hit 140mph every time I run logs in 4th gear. I've just never felt the need to shift and see how much faster it can go

Actually 160 MPH (257 Km/h) is 155 MPH (250 Km/h) on the GPS, BMW are intentionally increasing their speedometer by around 3%.

How to remove that speed limiter please? I have BM3 St1 and with that can go only 162 per speedometer.

I think that speedo stops at 300km/h. I reached 300 on the clock and RL showed 298
