C32 vs E46 M3
The E46 M3 is known to have relatively inaccurate speedo.
E46 M3 speed limiters are based off a sensor in the differential, and not the actual speedometer. Therefore, the limiter will 'engage' in a specific gear at a specific engine RPM.
As a result, if you surpass the 'limiting speed' (i.e. 155mph) in 5th gear, and then shift to 6th, you can easily surpass 155mph. The limiter kicks in at ~6,500 rpm whilst in 6th gear.
That corresponds to ~175 mph.
Time to move on.
Either way, good run and keep the videos coming. Let the M3/C32 war rage on!
